Tactile sensor - Smart, individual, simple, extravagant, futuristic - touch sensors, also known as KNX buttons, like to attract admiring glances and their modern design alone suggests to every user that this is more than a conventional light switch. Rockers, glowing LEDs, small symbols or even LCD displays give an idea of the numerous functions hidden behind many an installation. In addition, there is often a very noble selection of materials such as high-quality metal, acrylic or glass, which always exudes a touch of extravagance. But why are multifunctional touch sensors needed and how do you use their potential optimally? We give you a brief insight here.The basics in a nutshellTouch sensors are multifunctional control elements for the smart home.The design and function selection is huge, from a single button to a control center with 12 or more buttons, everything is possible.You can use it to control, for example, the light, its dimming, blinds, heating, entertainment center, door opener and all other devices in your home network.The button functions can be assigned individually and can be easily reprogrammed if necessary.Integrated LEDs or other displays often show the respective operating status or provide information about errors.   What is a touch sensor or a KNX button?You can operate the end devices integrated in your smart home network with a touch sensor or a KNX button. This can be blinds that you can raise and lower - light that you dim - the heating that you regulate or completely individual, user-defined scenarios. Depending on the model, operation is optically individual. In general, it is operated using a different number of buttons or rocker switches and/or even displays.The different types of KNX buttonsUsing a KNX universal button interface, you can basically turn any conventional button into a KNX button. These interfaces are installed in a deep device box behind the standard button and thus take on the task of the binary input, which converts the classic switching processes into KNX signals.Which doses are suitable?To do this, use a branch switch box with 4 screw domes or a deep switch box or an electronics box. Use our eibabo® search to quickly find the right item.This solution is particularly suitable for the standard application 'basic lighting' per room (see: 'What are standard applications?') or for the modernization of existing installations as well as for inexpensive and functionally manageable system extensions.'Real' KNX tactile sensors are much more complex and range up to control elements with elegant touch displays. Temperature sensors, LED displays and background lighting are often already combined in one device. In contrast to the simple interface variant, there is often the option of providing each key with additional functions, which are then triggered, for example, by a long press, double-click or even triple-click. TIP:We recommend planning well in advance so that you can later fit all the functions you need into your keypad. While some KNX push-button sensors require a separate bus coupler to which they are plugged, the bus coupler is already integrated in others. The eibabo® technology store also has both complete KNX pushbuttons and pushbutton sensor modules. The latter is 'only' about the technology and you can choose a matching design cover yourself. The possibilities are diverse - you can choose exactly what suits your project.The advantages and disadvantages of tactile sensorsThe central control of a large number of actions on different end devices is certainly the greatest advantage. The plus in comfort is combined with the flexible options for changing and expanding a well-planned setup. The disadvantage is certainly the slightly higher acquisition costs of a smart home solution compared to a conventional electrical installation. In the case of units with many keys and each assignment with different control variables (print, double-click), the overview of all the functions and their control can easily be lost.Unusual application examples in everyday lifeWe have already mentioned a few classic use cases. In the course of our more than 25 years of work, we have also been able to implement 'very special' projects. It starts with the smart opening and locking of the cat flap in the basement, continues with the choreographed lighting of exterior facades and doesn't end with the automatic pool cover, the fully automated aquarium or the heated driveway in winter.  You want to know more? We answer frequently asked questions.Nobody knows everything and sometimes there are small ambiguities that prevent us from correctly grasping connections or from deciding on one or the other product. You may also find an answer to your question in the following topics.How are the KNX devices programmed?Many interested parties are quickly startled by the term 'programming', but it's not that difficult at all, because it's not actually programmed with the 'ETS', but assignments and parameterizations are carried out.What does ETS mean for KNX?The term ETS (Engineering Tool Software) means that it is programming software for commissioning the KNX devices. The tool is more of a software for parameterization and basically also suitable for laypersons with an interest in the logic of the KNX.No programming knowledge or programming language is required. If you are interested in the rather simple logical connections of the KNX bus, you are in a position to create a project. Of course, more complex projects require a certain amount of experience. We always recommend having the basic project created by an experienced system integrator. This allows you to easily change important parameters yourself later on, since many things change in the life cycle.Which touch sensor or KNX button should I buy?Well, we can't give a general answer to this question, but we can perhaps provide some impetus for decision-making. KNX push button sensors are available in a variety of designs. The manufacturers offer solutions for every taste. However, you should not only be guided by the optics. In addition to the optics, eibabo® also recommends checking the applications (parameters and functions) provided by the manufacturer for the ETS (Engineering Tool Software). Significant deficits can open up here in the course of a project if the beautiful button were not able to control the necessary actions correctly. Plan exactly which requirements you place on the respective push button sensor and then select a suitable model accordingly. NOTE:ETS is standardized software for commissioning the KNX devices and can be obtained from www.knx.org. With regard to the design, you should also rely on optics that have a positive effect in the long term and not follow every short-term trend, only to realize a few years later that the brightly colored displays and the LEDs for various status messages on the buttons in the wall were a bit too much of a good thing. It makes sense to ensure that displays can be dimmed or configured in different brightness levels and status LEDs can be configured and switched off. A timeless surface design, for example, has simple elegance, looks classy, is durable and has no playful rockers that could quickly gather dust.How do I recognize whether a touch sensor already has a bus connection?Some touch sensors already have a bus connection. If you're not sure, a look at the back will clarify.Image: KNX push button sensor - Jung 4047TSMA touch sensor is equipped with a bus coupling if it has a black and red (or gray and red) terminal for the bus on its back. This 4-wire terminal with plug-in terminal connection serves as a distributor for up to four KNX lines.How do I keep track of the individual functions of complex touch sensors?We would like to encourage you to think: Imagine you come into a room and have to press the small second rocker from the top left on an 8-way pushbutton sensor every day to switch on the basic lighting. It can quickly happen that you accidentally set the pressure point on the adjacent rocker and unfortunately operate the blinds at 11:00 p.m. Not to mention how a guest or child is supposed to cope with it.So it can indeed be a bit difficult to always steer correctly. But: The advantages of the KNX lie in the intelligence of the system, which is implemented by the system integrator based on their experience and your functional requirements. For this reason, you should arrange functions logically or thematically and, if necessary, group them on easy-to-use buttons. If necessary, it is advisable to divide standard applications and detailed circuits into different buttons at different mounting heights.What are default applications? What is the best way to implement this into the system?The first switch box is usually placed on the 1.05m upper edge of the finished floor. At this point you should mount a conventional double button and connect it twice to the bus via a very inexpensive KNX button interface. Of course, you can also mount 2 or 3 double buttons and integrate a 4-way or 6-way KNX button interface. A deep switch box or electronics box is installed as a flush-mounted box in order to be able to place the small button interface behind the double button.Here you save!Combine a KNX button interface with a conventional double button.With the conventional double button, you have more choice in the design of the switch range and, in the event of defects or design changes, you can obtain a lifetime replacement without having to reprogram. You can assign the most important and most frequently used basic lighting to this button or parameterize the button or the button interface with light scene recall. A beautiful flat switch is also very easy to use for guests and children.What is meant by detailed switching on the KNX button?You should mount detailed circuits of the certainly many functions in a room on the 1.60m upper edge of the finished floor and call them up from a room controller or multiple push-button sensor with an optionally integrated room temperature controller (see also our multiple control unit catalogue). A room temperature controller already requires this mounting height for optimal control. At this user-friendly height, you can then carry out all additional controls for additional lighting, blinds, roller shutters, entertainment, etc.Touch sensors wear out very quickly! Is that correct?Like all other technical components that are used more or less every day, tactile sensors and control points in general are subject to a certain amount of wear and tear. However, this is no different than with conventional buttons or switches. It is possible that individual parts that have been in use for a decade are then worn out.Does it make sense to control the heating using touch sensors?Definitely, as a rule, individual room heating controls are also required for KNX installations. In terms of value for money, the combined buttons with room temperature controllers are the best choice, also in terms of user-friendliness.Which manufacturer offers the most beautiful and best KNX buttons?Beauty is in the eye of the beholder, we won't take a position on that. In terms of quality, however, all brands perform very well. There is no such thing as the 'best' touch sensor. Each manufacturer has its individual strengths in terms of applications (parameters and functions). eibabo® offers switches from all brand manufacturers (from ABB, Berker, Busch-Jaeger, Gira, Hager, Jung, MDT, Merten to Siemens). Select KNX push-button sensors in the following versions: KNX push-button sensor, KNX sensor unit, KNX wall sensor, KNX room control unit, KNX push-button sensor module, KNX push-button sensor extension module, KNX push-button 1-fold, KNX push-button 2-fold, KNX push-button 4-fold, KNX push-button 5-way, 6-way KNX button, 8-way KNX button, KNX control panel, KNX button with bus coupler, KNX button module, KNX touch sensor, KNX button sensor plus, KNX glass button.  Catalogue content:In this eibabo® catalogue Installation bus systems > Touch sensor for bus system you will find items from the following product groups:Item overview:Adapter frameBuilding controlBus couplerBus technologyButton couplerCabel CanalColor displayContactlessControl elementGlass buttonGlass sensorGroup button bus couplerLight scene touch sensorsNickel metallicOutdoor areaPendulum fanReceiving sensorRemote controlRemovable fanShutter buttonSingle rockerSplash proofTactile sensorsTemperature sensorTitle blockTouch sensorWireless pushbuttonWireless solutionfrom the following manufacturers:Manufacturer overview catalogue Tactile sensor:ABBAVM ComputersystemeBerkerbticinoBusch JaegerEatonElsnerESYLUXGiraHagerIssendorffJungLingg & JankeMaicoMDTMertenRopagSiemensTheben
Bulb socket - Of course, if you want to mount a new lamp, make sure that you use the right socket. There are, however, a large number of different versions, all of which have special or individual properties. Which socket you need can depend on the one hand on the amperage and on the other hand on the space available in the lamp. We will introduce you to the differences and similarities and support you in your purchase decision.Basically, the selection is huge and most of the differences are clear. Inexpensive plastic frames are available in the eibabo® shop as well as versions made of high-quality ceramic. You will also find models with different diameters and sockets into which the bulbs are screwed or clamped. Speaking of light sources: Last but not least, the choice of light bulb also determines which socket must be used. The counterpart to a socket is the so-called base of the light source. Proper functioning of the lamp can only be guaranteed if the base and socket fit together. TIPThe frames offered here are attached individually. Choose from models with screw holes, screw lugs, spring clamps, threads or mounting brackets. However, there are also distinguishing features, the purpose of which often only becomes clear at second glance. At this point we give you a small overview.Which lamp holders are the most common?The base is an indispensable element of any light source, since it performs the function of fastening and power connection. By connecting the base to the lamp socket, the lamp / illuminant is fixed to the light and supplied with energy. Of course, the lamp base and lamp socket must be of the same type, otherwise the connection will fail. Now one would think that this is self-evident and does not pose a problem in everyday life.Yes and no: Because the times when there were only lamp sockets with a thread are long gone. The modern world of lamps is now so diverse that the market for base types and the required lamp sockets has become very confusing. The manufacturers of modern lighting are constantly developing new variants. With a spontaneously bought lamp, you quickly acquire a surprise in the form of a previously unseen lamp socket. It's good if the first lamp is already there. But nothing lasts forever. Sooner or later it's time to replace a burned out lamp with a new one. We present the most common forms of lamp holders. Essentially, these are divided into screwable and pluggable sockets.E40 - screw socket for lamps with an output of more than 200 watts at 230 volts (use in the industrial sector or with conventional street lighting)E27 - classic standard screw socket for household lamps up to 60 watts at 230 volts with a plastic socket, up to 200 watts at 230 volts with a ceramic socket (usually used for Edison bulbs, energy-saving lamps, filament and LED)E14 - screw socket for lamps with an output of up to 60 watts at 230 volts (usually used for Edison light bulbs, energy-saving lamps, filament and LED)GU5.3 socket for simple plug-in pins with a spacing of 5.3 millimeters (often used in low-voltage spotlights with reflectors)GU10 sockets with bayonet lock, into which two solid pins are inserted, a quarter turn establishes the electrical connection (often used with spotlights with reflectors)G4 - receptacle for U-shaped plug pins with an average spacing of 4 millimeters (found in small halogen glass lamps or LEDs)G5 - Bayonet jack for fluorescent tubes with a pin spacing of 4.75 millimetersG13 - Bayonet jack for fluorescent tubes with a pin spacing of 12.7 millimetersG9 - receptacle for U-shaped plug pins with a mean distance of 9 millimeters (found in halogen glass lamps or LEDs) And that's by far not all. Here in the eibabo® shop you will also find sockets with the designations E10, R7s, 2G11, GX5.3, GZ10, G23 and around a dozen others.The 'E' in the screw sockets stands for Thomas Edison, the developer of the corresponding socket thread. The following number describes the diameter of the thread in millimeters. The 'G' is used for plug connections, with the following number indicating the mean distance between the two plug pins in millimeters.Image: Houben 102599 E27 lamp holderWhat material should I choose for lamp holders?When choosing a lamp holder, you often have a choice of different materials. You can choose from different metals such as aluminium, steel or brass, several plastics and ceramic/porcelain sockets.What is Bakelite?Bakelite is a thermoset phenol-formaldehyde resin that is easy to form during manufacture and has high resistance to electricity, heat and chemical attack. It was the world's first commercially successful plastic. It is rarely used today because once a product has hardened, it cannot be melted down and recycled.The main difference between these materials is their ability to withstand certain temperatures. For a rough estimate of which material is right for you, you can use the following information: modern plastic frames can withstand temperatures of up to around 210 °C, Bakelite is resistant up to 190 °C, ceramic frames and metal frames tolerate 230 °C and more. The higher the wattage rating on the bulb, the more heat is generated. For high heat output bulbs or special heat lamps, metal or ceramic sockets are usually the best option.How is the power connection to the lamp socket?Another difference is the type of cable connection. Here we distinguish between a detachable and a fixed connection. The fixed connection is usually made by soldering. In these cases, the lamp socket only has the contact pins required for this, to which the wires of the cables must be soldered. More often you get lamp sockets with detachable connections. These are made either via a screw connection or a plug-in connection / clamp connection.Whether you should opt for a lamp socket with a plug connection or a screw connection essentially depends on the type of cables you have. Modern lampholders offer special connection points, where the wires are fixed just by plugging them in with a spring mechanism. To loosen this connection, the tension on the spring is usually released with a pointed tool. This method of assembly is simple and quick. However, you need stable wire ends for this. You only have this for cables with solid conductors or when using ferrules. With flexible lines (finely stranded cores, strands) you cannot establish a secure connection in this way. If you have flexible cables, you should use sockets with screw connections. This method is a little more time consuming, but you'll attach the wires tightly and securely. Solid conductors can also be easily connected using the screw method.  Catalogue content:In this eibabo® catalogue Accessories for lighting > Lamp holder you will find items from the following product groups:Item overview:Adapter socketAluminum frameBuilt-up versionBulb socketCeiling mountConnection lineConstruction versionFestoon holderHanging versionIllumination plugInstallation setJunction boxLamp baseLamp holderLamp socketLighting holderMiniature versionPendulum socketPlastic framePorcelain settingRecessed socketRubber plugScrew socketSealing ringSmall versionSocketSocket adapterThrough socketfrom the following manufacturers:Manufacturer overview catalogue Bulb socket:BachmannBJBBrumbergEVNHoubenIDVKleinhuisPaulmannRenzScharnberger+Has.SchuchSignify LampenSLV
Antenna socket - Regardless of whether they are received via cable, satellite or terrestrial, radios and TV sets can be found in almost every household. And to establish a connection with the corresponding signal transmitter, one typically uses the classic antenna socket, which is actually present at least once in all modern apartments. Simple versions have the so-called Belling Lee socket for the television on the left and the Belling Lee socket for the radio on the right. More modern multimedia sockets can offer additional ports for connection. The well-known F-socket with the thread, which can be used for connecting a satellite receiver, for example, is widespread. Inexpensive antenna sockets with two, three or four connection options are available here in the eibabo online shop.Catalogue content:In this eibabo® catalogue Antenna and satellite technique > Antenna socket you will find items from the following product groups:Item overview:2-fold junction box2-way through socket3 hole through socket3-fold junction box4-fold junction box4-way through socketAntenna socketAntenna socket boxBK antenna socketBroadband socketData socketEnd socketEnd socket for antenna technologyFilter boxJunction boxLoop-through socketModem boxModem socketSAT double-pass socketSAT junction boxSAT pass-through socketSingle doseSingle/end boxSocket outletThrough socketTWIN branch socketTWIN end socketUniversal boxfrom the following manufacturers:Manufacturer overview catalogue Antenna socket:Astro StrobelBerkerBusch JaegerE+P ElektrikElsoGiraHagerHirschmannHomewayJungKathreinKreilingLegrand BticinoMertenOBOPehaPROTEC.classSiemensSpaunTechniSatTehalitTelevesTriaxWisi
Earthed plug - Electricity is essential in all areas of daily life these days. Whether household appliances, entertainment or even driving a car - nothing works without electricity. But not only the use of electricity is important, the secure connection of the electrical devices is also crucial. SCHUKO plugs are used here. These plugs are reliable and guarantee a stable connection between the devices and the mains. SCHUKO is the abbreviation for protective contact and a system of plugs and sockets. The SCHUKO plug is part of this plug-in system, which can be plugged in and unplugged under electrical voltage or load.What is a SCHUKO plug?SCHUKO is a system of mains plugs and sockets of the CEE 7/4 standard. These are also known as Type F connectors. Type F plugs are used, for example, in Germany, the Netherlands, Portugal, Austria, Spain, Sweden, Finland, Norway and many countries in Eastern Europe.Already knewThe grounded SCHUKO plug in its current form was patented in 1929 by Siemens-Schuckertwerke AG. This was preceded by a patent by Albert Büttner, who designed the basic shape of the plug and held all the necessary parts together with just a single screw.SCHUKO plugs and the associated sockets are usually equipped with a protective earth and are intended for use in 230-volt networks with a current of 16 amps. SCHUKO plugs and sockets are unpolarized. That means: outer conductor and neutral conductor are randomly connected. In addition to the outer conductor and the neutral conductor, the system has a green-yellow protective conductor, which takes over the protective earthing with two flat contacts at the top and bottom of the plug. When plugged into a socket, the SCHUKO plug closes the connection cavity of the socket and thus prevents contact with conductive components when making contact. First, a ground is established between the flat contacts of the plug and the grounding terminals located in the socket. Only then do the phase conductor connections and the neutral conductor connections come into contact with one another. And it is precisely this fact that is special about the SCHUKO system and gives it its name: the protective contact connection diverts dangerous voltages as soon as the electrical circuit is closed by the other two poles. This design with leading protective contact ensures that there are no dangerous voltages on accessible parts of the device.Additional lateral guide slots in the socket are required for reasons of stability. These enable the use of large and heavy SCHUKO plugs, for example with a built-in transformer or timer.Image: Mennekes 10837 Schuko plugBasic information on the typification of plugs and socketsThe plugs and sockets that exist worldwide are numerous and correspondingly different. Their design and structure is often historical and adapted to the conditions of the power grid in the respective region. Worldwide, we distinguish between two standards for wired AC transmission. On the one hand, this is the 230 volt standard with a frequency of 50 Hertz / 60 Hertz. On the other hand, it is the 110 volt technology with a frequency of 50 Hertz / 60 Hertz. Based on this, individual countries and manufacturing companies began to offer their own connectors. This led to a high degree of individualization. The introduction of a globally standardized plug system failed on the one hand because of political sensitivities, wars and conflicts and, of course, because of the two already established transmission standards. Because there would be a risk of devices being damaged or short circuits or fires occurring if a device were connected to a network with a voltage other than its nominal value. As a result, the development of adapters and transformers was accepted instead to achieve cross-system international compatibility.NoticeThere are currently 15 plug / socket standards worldwide, referred to as plug types A to O. Here in Central Europe, types C, E and F are used, some of which are also compatible with each other.The Type-C plug is an unearthed two-pronged plug that used to be standard in most European countries as well as in the countries of the former USSR. This type is considered the forerunner of today's French type E and the German type F. Type C plugs are still often found in the form of flat plugs on many devices such as fairy lights, floor lamps, razors, hair dryers and other small household appliances. In the international CEE system, this plug shape is referred to as the CEE 7/16 standard. Type C plugs fit perfectly into a Type F SCHUKO socket.With the French type E plug, there is a grounding contact for the protective conductor in the center above the pins for the phase conductor and neutral conductor. The counterpart to this is a pin that protrudes from the French Type E socket. Classic plugs of this type are usually round and do not fit into the Type F SCHUKO socket because the lateral guide grooves and the recess for the earthing contacts attached at the top and bottom are missing. However, these are only very rarely found and are increasingly being replaced by CEE 7/7 plugs, which fit both type E sockets and type F SCHUKO sockets.The German Type F SCHUKO plug is widely used throughout Europe, as well as in Russia, Belarus and Ukraine. This is characterized by the grounding clamps at the top and bottom and by a guide groove on the right and left. In the international CEE system, this plug shape is referred to as the CEE 7/4 standard and is not compatible with the French Type E socket due to the lack of a recess for the grounding pin. This is why it is now considered obsolete. In the course of a homogenization of the European market, this plug is often replaced by the CEE 7/7 plug, which is a hybrid E/F plug. The CEE-7/7 SCHUKO plug is therefore the current, grounded and universal continental European standard:with grounding clips on both sides to match with Type F socketwith a socket contact to accept the ground pin of the Type E socket  by the wayThe socket of the SCHUKO socket is set back by 15 mm so that there is no risk of electric shock if the plug is partially inserted. Both the SCHUKO system and the French counterpart are designed for a nominal voltage of 230 volts at 50 hertz. All components are designed for 16 amps as standard. At 230 volts, this corresponds to an output of 3,680 watts.What is a contour plug?In connection with SCHUKO plugs, we often hear the term contour plug. A contoured plug is a two-pole (i.e. unearthed) plug that has the necessary recesses for the German grounding clamps, the guide grooves and an additional hole for the French protective conductor contact on the rounded edge of the plug. The plug thus fits into both systems, but does not use the protective contacts.At eibabo® you will find not only classic SCHUKO connectors, but also 2KT SCHUKO connectors (for difficult conditions), duroplastic connectors, flat connectors, flat cable connectors and flat connectors. Rubber plugs and PVC SCHUKO plugs as well as assembly plugs, angled plugs and wall plugs are also available for the SCHUKO system. In addition to the protective contact plugs of the SCHUKO system, we also carry protective contact plugs of the Swiss system and the English plug system. Please noteSCHUKO plug connections are not always compatible with other safety plug systems. SCHUKO plugs from all approved and well-known manufacturers are offered here in the shop, including ABL Sursum, Berker, Bachmann, Merten, Mennekes, Gira, Busch-Jaeger and Apsa.  Catalogue content:In this eibabo® catalogue Domestic switching devices > Plug with protective contact you will find items from the following product groups:Item overview:Angle connectorBelgium clutchBelgium plugConnectorConnectorsDevice connectorElamide connectorEuropean plugFrance clutchFrance plugFrench plugHousehold plugProtective contactRubber plugSafety plugSchuko plugSocketsSolid rubber plugfrom the following manufacturers:Manufacturer overview catalogue Earthed plug:ABLBachmannBalsBerkerBusch JaegerE+P ElektrikElsproGiraHartingHirschmannJungKleinhuisLegrand BticinoMennekesMertenMeyerSchulteWalther
Bell transformer - The ringing, ringing or humming at the door, whether with a gong or a melody, keeps us in suspense. Who will be standing outside? In order for the doorbell to work reliably, correct installation is mandatory. Since the classic doorbells mostly work with voltages between 8 and 24 volts, you cannot connect them directly to the 230V voltage of the house. A bell transformer ensures a voltage reduction and prevents burnout as soon as current is applied via the bell button. Roughly speaking, such a transformer diverts excess current from one coil to another coil on the input side and thus ensures the correct voltage on the output side. You can find a large selection of high-quality bell transformers from various manufacturers here in the eibabo online shop.

Actuating drive - Do you want your heating systems to offer the desired living comfort while working efficiently? Then it should be equipped with durable and high-quality actuators that optimally control the flow of the heating medium. Find out more about actuators, their function and use here. Actuators are required to open and close the water circuit of a heating system or cooling ceiling. To do this, the drives are screwed or snapped onto a valve. Efficient heating of buildings has become a challenge. It is no longer just about warming the residents, but:adjust the temperature sensibly to the function of the roomusing as few resources as possibleto ensure a long service life of the systemto enable convenient operation All of these lead to money savings, environmental protection and a better quality of life, and depend in part on the heating system installed in the building. In this eibabo® catalog you will find conventional actuators for 24 volt systems or 230 volt systems. Depending on your needs, choose normally open or normally closed models and installation accessories.What are thermoelectric actuators?Thermoelectric actuators are general purpose actuators designed to provide on-off control of a variety of control valves. In private use, these are typically the valves of underfloor heating, but can also be used in industry for other heating systems, ventilation systems and cooling systems. The devices regulate the flow of the heating medium (e.g. hot water) in a circuit and thus ensure that the temperature in the building is controlled. Thermoelectric actuators can be used on the heater valves as well as in the heater manifolds and the floor manifolds.Please noteSome actuator models only suitable for certain valve inserts. Please read the product descriptions and pay particular attention to the dimensioning of the attachment on the valves and the type of power supply.Modern actuators work together with room thermostats and heating actuators and can be integrated into the building management system.Should I buy normally open or normally closed actuators?With actuators, we distinguish between NC (normally closed) and NO (normally open). Which variant you choose depends on your personal needs. NC drives are always closed and open when power is applied. In the case of normally open NO actuators, the current ensures that the valve closes. Please take this into account when planning your heating system. But what are the advantages or disadvantages? In the event of a power failure or defect, NC drives close. If it is a heating season, you will quickly notice the malfunction. It's getting cold in the house. NC drives therefore only consume electricity when they are being heated. On the other hand, drives that open without current are more efficient during the heating period. However, in the warm season you must keep the drives closed using electricity, otherwise you may heat your building unnecessarily. In such a case, switching off the pump by the heating actuator or manually after the winter season would be advisable.How are thermoelectric actuators installed?Thermoelectric actuators (valve drives) are snapped or screwed directly onto the upper part of the valve used in the house. This connection with the valve spindle is usually made directly in the heating circuit distributor. You can use adapters made of PVC or metal to compensate for the manufacturer-specific distance differences between the drive and the upper part of the valve or the thread and the mount. In this way you ensure correct implementation of the manipulated variable.Why are there no KNX actuators?With a decentralized installation, for example in the heating circuit distributor, you can use heating actuators with L and N connections for direct connection of the actuators. You can find more information in our 'Heating actuator' category. Contrary to widespread opinion, thermoelectric actuators are not wear-free and must be replaced every year. This is why earlier versions of expensive KNX actuators (i.e. devices that combine the KNX actuator and actuator) have not caught on and are increasingly disappearing from the market. It is therefore a question of long-term cost efficiency to separate the technology from the positioning drive and the actuator. The actuator is parameterized using the Engineering Tool Software ETS. TIPThe ETS parameter 'Flush' helps to minimize wear on rarely used valves. This function prevents the heating valves from calcifying too quickly. This KNX software is manufacturer-independent and is required to develop and configure individual controls for building automation. That means: The actuator opens and closes the actuators according to the programmed specifications.What should I look out for when buying an actuator?Reliable working actuators are the key to the correct and efficient operation of the entire heating system. When selecting thermoelectric actuators, you should pay attention to the following points:The drives must be compatible with the rest of the heating system. Check that these match the valves. An important parameter here is the so-called stroke, which is usually specified in millimeters. The stroke of the actuator must match the closing dimension of the valve. If the stroke is too small, the actuator will not fully open or close the valve (depending on the NO or NC variant).Decide on a normally open or normally closed variant.Pay attention to the power supply. Here we distinguish between 24 volts and 230 volts.The power consumption of the drive should be as low as possible and not exceed 5 watts.Opening and closing a valve takes time. High-quality equipment offers opening and closing times of less than 3 minutes.The actuator should have an easily recognizable status display so that the current status can be easily read. Image: ABB TSA/K 230.2 thermoelectric actuatorIn addition to thermoelectric actuators, we offer you the following products:radiator valve drivesActuators including binary inputselectromotive actuatorsRadiator control drivesWireless actuators with and without room temperature controllerRadiator thermostatsstraight valvesvalve adapterReceiver for heating actuatorsand many more Well-known brand manufacturers in our range include ABB, Busch-Jäger, Eaton, Gira, Hager, Heimeier, Issendorf, Lingg & Janke, Merten, MDT, Siemens, Somfy and Theben.  Catalogue content:In this eibabo® catalogue Installation bus systems > Actuating drive for bus system you will find items from the following product groups:Item overview:ActuatorBattery poweredBus technologyContinuous controlControl valveEnergy efficientHeater driveHeating controlHeating controllerHeating technologyRadiator thermostatRetrofitRoom temperature controllerRoom thermostatTemperature controlTemperature controllerThermostatTime profileValve driveWax cartridge drivefrom the following manufacturers:Manufacturer overview catalogue Actuating drive:ABBAVM ComputersystemeBusch JaegerEberleEltakoFKRGiraHagerIssendorffJungMertenRademacherSiemensSomfyThebenWindowMaster
Combi i/o device - Combi IO devices are essential components of complex building automation. Find out here how to use the high-quality IO devices and what options there are for your installation. In any case, these devices increase the efficiency of your installation. Learn more about these modules and why it is so important for them to work properly.What is an IO device?An IO device - also known as an input-output module - enables communication between a computer system and a peripheral device. This type of processor communication between devices increases a computer's capabilities. The operating system is enabled to connect to the outside world. Communication and interaction takes place through sending and receiving information. Possible input information are, for example, signals from user inputs or binary inputs. Output signals are sent by the system or converted into actions as manipulated variables by actuators. With the use of a multifunctional input module, the work can be carried out more efficiently and accurately. Typical IO devices include:KNX universal interfacesKNX universal controllerKNX switching actuators with integrated binary inputsKNX button interfaces with outputs for LED controlspecial KNX room controller with a variety of special functions  TIP:An IO device can interface with a large number of bus protocols, for example PC Cards, USB, PCI, VMEbus and FireWire. In this eibabo® category you will find, for example, KNX devices with multiple functions from top manufacturers such as ABB, Berker, Busch-Jaeger, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens and Theben.What are the most important functions of an IO device?An IO device is an essential link in the control chain and closes the gap between your computer system and the external devices. It can perform multiple functions including:Communication between the devices in the systemAn IO device assumes several functions within the scope of device communication. This includes the transmission of status messages, the sending of commands and the transmission of information.communication to the processorFull communication with the processor includes recognizing its own IP address, decoding and accepting commands, and reporting status updates.error managementAn IO device detects different types of problems that can occur between the computer system and a peripheral device. These can be mechanical problems, such as a used printer cartridge or errors that occur during data transfer.Image: ABB IO actuator 8-fold IO/S8.6.1.1timingIn order to be able to correctly manage the flow of information between the system and the external device as part of time management, the IO device accesses the internal resources of a computer.data bufferingOne of the most important functions of an IO device is managing the transmission speed between memory, processor and other external devices.How and where can IO devices be mounted?There are many options for mounting IO devices and they depend on your existing installation. Choose from the following options:Panel mounting - the unit is bolted to a chassis or attached to a panelRack mounting - the device fits into a standard housing, such as a 19-inch rack or similarInstallation on DIN rails - the device is attached to one of the common DIN rails or G-railsfree installation - the device has a stable housing and is set up in a freely selectable placePrinted circuit board assembly - the device plugs directly into computers or is attached to the case What advantages do IO devices offer?Depending on the IO device involved, each can play a significant role within an effective operating system. In a programmable logic controller (PLC) and other operating systems, these devices offer the following advantages:a compact design saves space in almost any assembly environmentthe installation can be done remotelyHardware and associated costs can be savedthe wiring and cable setup is simple and clear What are the properties of the inputs and outputs on the IO devices?As a rule, IO devices offer digital channels, analog channels or a combination of both variants. The digital inputs and outputs handle low-level on-off signals. Analog inputs recognize signals such as current, voltage or frequency. Devices with combined channels often process the signals using analog-to-digital converters.The input channels of a device are differentiated as single-ended (SE) or differential (DI). Single-ended inputs consist of two contacts, one of which carries a voltage. The other is connected to ground. Such installation is simpler and cheaper than differential signaling. However, the inductance of the signal line and the difference in ground voltage between the transmitter and receiver will cause noise interference. Differential communication uses two mutual signals on two paired contacts. The difference between the two signals represents the meaningful signal value. Common-mode rejection prevents noise interference. Differential inputs respond to the voltage difference between the two contacts. These are therefore suitable for low-voltage, long-distance and high-resolution applications. The type of input channels your device has can usually be found in the product description. For example, if you have a 16SE-8DI device, it offers 16 single-ended and 8 differential inputs.isolationCertain areas of the electrical system can be isolated from others. This avoids unwanted current flow or signal flow between the areas.For isolation, please distinguish between channel-to-channel isolation, isolated analog input, isolated analog output, isolated digital input, and isolated digital output.  Catalogue content:In this eibabo® catalogue Installation bus systems > I/O device for bus system you will find items from the following product groups:Item overview:Blind controlCentralAccessControl deviceControl elementControl panelControl unitDrive elementDriver moduleEngine control unitHeating actuatorHome serverInput moduleInterfaceJunction boxLight actuatorMixing moduleMulti-controllerOutdoor areaRadio systemSecurity adapterShutter actuatorSmartphoneSun protection actuatorSwitching actuatorSwitching outputUniversal interfaceWireless solutionWireless switching outputfrom the following manufacturers:Manufacturer overview catalogue Combi i/o device:ABBBusch JaegerGiraHagerLingg & JankeMetzSiedleSomfyWaremaWindowMaster
Wall-mounted housing - Do you have a prefabricated concrete garage and want to install a socket in it? Or do you need a light switch in the woodshed? In these cases it is not possible to lay the electrical installation in such a way that it runs inside the walls. Here you only have the installation on the wall. As a result, light switches, sockets and other end devices must also be mounted on the wall. There are special surface-mounted housings for this, in which socket outlets or various switch inserts can be accommodated. Depending on your needs, you can get the surface-mounted housings in different colors and designs in the eibabo shop. Some of them are specially designed and therefore also suitable for damp rooms or for outdoor use. Simply browse through our catalog and find the right product for you. We guarantee you a secure payment process and a short delivery time.Catalogue content:In this eibabo® catalogue Domestic switching devices > Surface mounted housing for flush mounted switching device you will find items from the following product groups:Item overview:3-fold surface-mounted housingAbutment spacer ringAP capAP frameAP housingAP mounting frameBuild-up housing 1-fold flat versionConnectors for hose fittingsDistance pieceHousingHousing for built-in deviceOn-wall frame 1xOn-wall frame doubleOn-wall frame tripleSpacerSpacer for special frames with 19 mm edgesSurface frame with clamping ringSurface mounted frameSurface mounted housingSurface mounted housing for flush mounted switching deviceSurface mounting frameSurface mounting housingSurface-mounted housingSurface-mounted housing 1-way flat designSurface-mounted housing 2xSurface-mounted housing for built-in deviceSurface-mounted housing for flush-mounted deviceSurface-mounted housing, 1-fold high designfrom the following manufacturers:Manufacturer overview catalogue Wall-mounted housing:ABBABLAssa Abloy effeffAstro StrobelBerkerBrand-RexBusch JaegerComelit GroupCommScope EMEACommScope/AMP NetconnCorningDätwylerEberleEFB-ElektronikElsoESYLUXGiraGrotheHagerHartingJungKathreinKindermannLegrand BticinoLegrand SEKOLeoni DatacomMaicoMertenMetzOBOPehaRademacherRutenbeckSiemensSomfyTehalitTelegärtnerTriaxWaremaWisi
Install. box - device install. duct - Device installation trunking is very often used where a lot of communication technology is required in a small space. The ducts themselves are wall mounted by default and include plenty of power and data cables. You can discover such installations in authorities as well as in car dealerships or supermarkets. However, the ducts are not only used to hide the cables, they are also potential connection points for power supply or network connections. The sockets, telephone and network connections required for this are installed and fastened in the ducts using the duct installation sockets. Depending on the requirements, the channels of the different manufacturers are dimensioned differently. eibabo has a range of high-quality, low-priced installation sockets for all trunking dimensions from the most common suppliers and will deliver them to your construction site quickly and safely.Catalogue content:In this eibabo® catalogue Installation ducts for wall and ceiling > Junction box for wall duct you will find items from the following product groups:Item overview:1-fold can2-fold can3-fold canAccessory mounting boxBuilt-in boxBuilt-in installation boxCEE built-in boxCEE built-in installation boxCEE installation duct boxConnector socketData socketDevice installation systemDevice socketDouble canDouble socketDuct boxDuct installationEnergy canInstallation box for device installation trunkingInstallation channelInstallation duct boxJunction boxJunction box for wall ductMounting frameSingle boxTriple canTrunking boxUniversal data socketfrom the following manufacturers:Manufacturer overview catalogue Install. box - device install. duct:KleinhuisMetzNiedaxOBOPROTEC.classRehauSchneider ElectricSpelsbergTehalitTelegärtner
Heating actuator - A comfortably warm bath after getting up or a cool bedroom at night - automatically. Who does not want that? Modern building automation makes it possible. The interaction of room temperature controllers, heating actuators and valve drives offers almost unlimited possibilities. The setup can be set up in all rooms according to the needs of everyday life.What are heating actuators?If you want to regulate the temperature in the room, in the apartment or in the entire building automatically, heating actuators play a central role. In principle, these are switching actuators. However, these are not equipped with mechanical relays. Thermoelectric valves (low ohmic loads) work here, which use electronic circuits (Triac) to ensure closed hot water circuits or chilled water (chilled ceiling). As a result, these devices are noiseless and wear-free.How is room temperature controlled via a heating actuator?The control difference determined by a KNX room temperature controller, i.e. the difference between the setpoint temperature and the actual temperature, is converted into a command value telegram. It is sent to the corresponding channel of the heating actuator via the KNX bus. Connect the thermoelectric (conventional) actuator to the duct using a suitable cable (e.g. NYM-J 3x1.5). The heating actuator can switch directly (1 bit) or independently process a received 1-byte command value signal internally. With the latter, the KNX bus is relieved because there is no flood of control telegrams from the room temperature controller to the actuator. Only the calculated control difference is sent to the actuator as a 1-byte command value telegram (0-100%). This converts the information into switching signals (on/off) directly to the assigned heating channel. This is called pulse width modulation (PWM). TIP:Make sure there are enough control channels on the heating actuator, ideally at least one per room. This creates maximum flexibility when controlling. The following small example illustrates the rough functionality, not the actual, manufacturer-specific control algorithm:The current temperature (controlled variable) is 20 degrees Celsius. The desired room temperature is 25 degrees Celsius and represents the set value for the controlled variable (command variable). The difference between the desired room temperature (set value) and the current temperature (actual value) is the control difference. The control difference is 5 degrees Celsius and is used to determine the manipulated variable that influences the room temperature. Assuming the manipulated variable is 20%. This value is sent to the heating actuator in the form of a 1-byte telegram (0-255 = 0-100%). The value 51 is therefore transmitted to the actuator. The time for opening/closing the actuator is stored in the parameters of the actuator using ETS. You can find this time in the properties of the respective 230V AC or 24V DC thermoelectric actuator. For example, the actuator takes 2 minutes to fully open. With a command value specification of 20%, the actuator would switch on the valve drive for 24 seconds (20% of 2 min.) and switch it off for 96 seconds. This process is repeated until the room temperature controller calculates and sends another command value specification. Depending on the manufacturer of the actuator, you can integrate several actuators per channel.How do I find the right heating actuator?The selection of a suitable heating actuator is linked to certain requirements. Answering the following questions will help you make a decision:How many heating circuits does my system have?How many actuators do I have per heating circuit?Do I want to install the heating actuator centrally or directly in the heating circuit distributor?Do I want to protect the power supply of the device via a connection for auxiliary voltage?With what voltage do the actuators work?Which functions should the heating actuator have?Do I prefer a certain brand?and many more The range of functions of a heating actuator in particular can differ depending on the model. Things to keep in mind include the following:Is it controlled with 1bit (switching/PWM) and/or 8bit (continuous) control values?Is direct control with a temperature value possible via the KNX bus?Does the device have an integrated temperature controller?Are the setpoints saved in the event of a bus voltage failure?Is there an emergency operation if the cyclic command values fail?Are different operating modes available (comfort, night, frost protection, summer mode or winter mode)?Is there a short-circuit detection and a voltage failure detection?Does the device have a pump shut-off? High comfortDepending on the model, it is possible to set a minimum comfort temperature for the underfloor heating. An additional sensor measures the temperature of the floor and keeps it at your comfort level. This is very pleasant in barefoot zones such as a bath.Depending on what value you place on the individual properties, the range of products can be limited to just a few models.Can I connect a heating actuator directly to the actuators in my heating circuits?In the case of a decentralized installation, for example in the heating circuit distributor, models with L and N connections can be used for direct connection of the actuators.Are KNX actuators really bad?Thermoelectric actuators are not wear-free and should be replaced every year. That is why expensive KNX actuators, which combine the KNX actuator and actuator, have not caught on and are disappearing from the market.Image: Jung Triac 2336-REG-HZR-HE 6-fold KNX heating actuatorHow are thermoelectric actuators installed?Thermoelectric actuators (valve drives) are snapped or screwed directly onto the upper part of the valve used in the house. This connection with the valve spindle is usually made directly in the heating circuit distributor. You can use adapters made of PVC or metal to compensate for the manufacturer-specific distance differences between the drive and the upper part of the valve or the thread and the mount. In this way you ensure correct implementation of the manipulated variable.How do I prevent rapid wear and tear on my valve drives?The ETS parameter 'Flush' minimizes wear and tear on valves that are rarely used, for example in summer or in bedrooms. This function prevents rapid calcification of the heating valves. Good to knowWith actuators, a distinction is made between NC (normally closed) and NO (normally open). NC drives open when power is applied. In NO actuators, the current closes the valve. Please bear this in mind when planning your heating system, as it is ultimately your personal decision. In the event of a power failure or defect, NC drives close and you quickly notice a malfunction. These drives only consume electricity when heating. On the other hand, drives that open without current are more efficient during the heating period. In this case, switching off the pump by the heating actuator after the winter season would be advisable. Otherwise you would continuously use electricity to keep the heating closed by means of the NO actuators in the warm season.Who are the leading manufacturers of KNX heating actuators?The leading manufacturers of KNX heating actuators at eibabo® are, for example, ABB, Berker, Busch-Jaeger, EIBMARKT, Elsner, Gira, Hager, Jung, Lingg & Janke, MDT, Merten, Siemens and Theben.
