Binary input - What interesting possibilities does the use of binary inputs in building automation offer you? Learn more about differences, use cases, and things to watch out for on this page.What do you need a KNX binary input for?KNX binary inputs are used to convert conventional alarm messages, fault messages, operating messages or status messages (generally analog signals) into digital signals and connect them to the KNX bus.Image: KNX binary input universal - Hager TXA306 for KNX building automationWhat should you know before buying a KNX binary input?Take a look at your project and ask yourself the following questions:Is it a new installation or do I have to consider the properties of existing devices (e.g. switches)?Which signals or voltages should be recorded?What is the distance between the signal transmitter and the receiver?Do I need additional cables and lines?Should the control only be wired or also possible via radio?Which logic functions do I want to implement?and much more The answers will help you to make the right choice for a suitable binary input. Among other things, this results in the number of channels that your new binary input should have, which manufacturer supplies an application (software) suitable for the project and whether the binary input must be suitable for potential-free devices or not.What is the difference between the individual binary inputs?The binary inputs are often provided in the variants 20V, 24V, 230V and potential-free. Which one you need in each individual case depends on which signals you want to activate. Notice:The addition potential-free, 20V, 24V or 230V does not refer to the binary input, but to the signal to be recorded. potential-free binary inputsPotential-free means that no external voltages (potentials) may be connected to the inputs at these binary inputs, since the contact voltage (usually 10-20V) is already provided by the binary input itself. The potential-free variant is typically used for buttons, switches, door contacts (magnetic or reed contacts), window contacts (magnetic contacts) or auxiliary contacts. Magnetic contacts may often only be assigned a maximum of 20V DC. However, the maximum cable length that can be connected is often limited to between 50-100m, see the description of the respective potential-free binary input and can also be negatively influenced by inductive or capacitive loads in the area around the routed cable. Devices with wires that have already been brought out should generally not be extended at all, eg button interfaces (a button interface is also a binary input). 20V and 24V binary inputsModels with 20V or 24V are used when devices cannot switch potential-free. These are, for example, presence detectors or differential pressure monitors for stoves that work with 24V technology. 230V binary inputsThe 230 V version is often used to connect existing 230 V AC signals to the bus in order to evaluate them. For example for conventional 230V outdoor motion detectors, buttons, switches or other messages from other systems. Fuses can also be monitored in order to immediately notice critical changes in large building complexes, for example. What specific applications can be implemented with KNX binary inputs?The possibilities are diverse and depend entirely on your project. A KNX binary input detects a status change at its input. Depending on the parameterization that you carry out using the software (ETS), a telegram is then sent to the KNX bus. This information can then be integrated into other desired functional logic, for example:Open windows = set heating to standby/frost protectionLevel reached = open valveTo evaluate a conventional 230V motion detectionFor activation of conventional buttonsTo capture status or operational messagesEvaluate error messages from connected devicesand much more Or you use the information for displays on displays, for touch functions or for visualizations for evaluation purposes.What is ETS?ETS is the abbreviation for Engineering Tool Software. This is used to assign and parameterize certain actions, relationships or functions within the building automation. So you determine what a binary input should do with an incoming signal. Programming skills or learning a programming language are not required. If you are interested in logical connections and can imagine the later function in the building based on an abstract scheme, the creation of a project should be a solvable task for you.We recommendIn the case of particularly complex projects, it can be advantageous to hire an experienced system integrator to create the basic project. This is typically much faster than doing it yourself and you will receive a tested, error-free basic version of your system. Later you can easily change, add or remove individual parameters yourself.You can think of the configuration as similar to the folder system on your Windows PC or iOS computer. You create your own structure and save files in it. In addition, you create shortcuts to other files and folders based on certain conditions. In the ETS, the 'folders' are floors or rooms, for example, and the 'files' in them correspond to sensors and actuators that you can relate to one another.Can consumption also be recorded and evaluated with KNX binary inputs?At eibabo® you will also find KNX binary inputs to record counter values. You can order almost all conventional water meters, electricity meters, gas meters, heat meters and many more including an S0 interface (pronounced: S-zero interface). This is used to transmit measured consumption values for further processing in the building automation. The interface sends an impulse via a contact, which corresponds to a certain value of the measured medium. The pulse value is always the responsibility of the meter manufacturer.An example: If you buy a water meter with an S0 interface, the pulse value is on the meter or in the product description, for example 10 liters = 1 pulse. That means the contact closes and opens again (rising/falling edge, 30 ms = t_ON = 120 ms 30 ms = t_OFF) as soon as 10 liters of water have been consumed. Simply put, the signal is similar to when you press a button. You can evaluate these contacts using a KNX binary input with the application provided by the manufacturer for counting value acquisition.As a rule, potential-free 20V or 24V binary inputs are used for this, as the contact voltage may be a maximum of 15V (S0 interface class B, short transmission paths) or a maximum of 27V (S0 interface class A, long transmission paths).Are long distances critical for signal transmission?Pay attention to the technically required maximum cable lengths between signal detection and binary input contact, especially with 20V, 24V and potential-free. These are often a maximum of 100 meters and should be routed in a protected manner without inductive or capacitive cross-influences. TIP:Please refer to the manufacturer information for this. The individual brands and the different variants have individual limit values. This applies in particular when critical states are to be monitored, such as counting for billing purposes (LIYCY lines, cables).How are KNX binary inputs mounted?KNX binary inputs are available with eibabo® for different types of installation, for example for installation in an electrical distribution board. These devices are referred to as modular installation devices (REG). There are also binary inputs for flush-mounting (UP) or surface-mounting (AP) and for integration in ducts or similar (EB).Which manufacturers of KNX binary inputs are recommended?In this eibabo® catalog you will find everything on the subject of KNX binary input, binary input device, binary input module, button interface, universal interface, input module, button coupler and evaluation unit.

Socket - A socket is much more than an inconspicuous power supply on the wall. Find out here which sockets are available and why you can never have enough of them. In addition to buttons and switches, sockets are among the most important products of all manufacturers of switch programs. A socket is installed either permanently on a wall (surface-mounted socket) or recessed (flush-mounted socket). Sockets can also be part of a mobile line coupling, such as table or multiple sockets. There are also sockets on extensions that are intended for mobile use. A socket is mostly used for the power supply. There are also sockets for telephone / telecommunications and for the data transmission sockets. Devices are usually supplied with single-phase alternating current (in Europe 230 volts) or three-phase alternating current (three-phase current with 400 volts) via classic sockets. There are also standardized sockets for 12V direct current. There are separate socket systems for the supply of higher voltages and currents.Basic information about sockets - in a nutshellA distinction is made between the flush-mounting and surface-mounting types. With the flush-mounted variant, sockets are mounted in switch boxes, which in turn are embedded in the wall. In the 'surface-mounted' variant, sockets are attached to existing walls, usually with dowels and screws.Double sockets are usually nothing more than two single sockets. They obtain the energy from the same supply line. Flush-mounted variants can be optically connected to one another via the frames of the switch range. With surface-mounted devices, both sockets are supplied in one housing.A socket insert is a device for installation in the switch box. It is either attached using claws (clamp connection) or by screwing the base plate of the insert to the screw holes of the switch box. The insert must be supplemented by the frame of the switch range.High-quality moisture-proof sockets usually have a self-closing cover and a rubber seal around the base. They are used in bathrooms, kitchens or utility rooms.Outdoor sockets must protect the current-carrying cables from rain and snow. Their housings are often particularly stable in order to prevent damage from mechanical influences.The degree of protection is a determining variable for the place of use. The best known is the two-digit IP protection class (IP = International Protection / Ingress Protection). The first digit stands for protection against contact and foreign bodies, the second digit for protection against water. The higher both digits, the safer. Planning of sockets - there is no such thing as too muchIf I were to build a house again, I would do many things differently.' You hear it very often like this or something similar when you talk to builders. Not infrequently, the planning and implementation of the electrical installation is one of the things that could be better. It is often the insufficient number of sockets that makes everyday life unnecessarily cumbersome. For example, if there is no socket in a dark corner of the room, you must lay an extension cord for the lamp. You probably won't connect very many electronic devices in a bathroom. A living room is usually equipped with many devices and is occasionally rearranged. Many sockets offer flexibility here. TIP:Sockets are very cheap to buy compared to the whole building. Do not plan too tightly, but generously. But positioning also plays an important role. Plan ahead with the layout of your home, the furnishings, and the purpose of the room. Think about the different uses throughout the year. For example, the following are often overlooked:Sockets in the window reveal to supply the Christmas lightsSockets at ceiling height for extractor hoods, infrared heaters and the likeSockets in the attic (for later expansion)the right sockets in hobby rooms, if necessary for devices that require three-phase currentOutside sockets on the balcony or terraceOutdoor sockets near a cistern or water barrel to feed a pumpOutside sockets in the carport or near storage areas for wood and the likeOutside sockets on the property line / driveway The Schuko sockets in the eibabo® online shopThere are many types of sockets. The so-called Schuko socket is the standard in Europe. The abbreviation SchuKo stands for 'protective contact' and is a designation for the German-speaking area. Internationally, these devices are referred to as type F sockets. Cables with three cores are connected to sockets of this design, one of which serves as a protective contact. This derives leakage currents. The matching plugs (e.g. on electrical devices) are also constructed according to this principle. In this catalogue, we present you with high-quality sockets from over 30 manufacturers, including Gira, Jung, Merten, Hager, Berker, Legrand BTicino, Busch-Jaeger and Siemens.How much load can a single socket withstand?A classic 230 volt household circuit is usually protected with 16 ampere fuses. This results in a maximum load capacity of the circuit of 3680 watts (16 amps x 230 volts). This means that you could theoretically draw 3,600 watts of power from a standard household socket. NoticeWhen it comes to electrical installation, it is advisable never to push individual devices to their capacity limits. In practice, about 2500 watts should not be exceeded at a socket. Based on Central European standards, 200 watts to 300 watts per individual socket is assumed in everyday use. With double sockets it is up to 500 watts. You should take this guideline into account when planning the maximum number of outlets per circuit for your installation.Does eibabo® also offer sockets of other standards?eibabo® is an international online mail order company and offers sockets that are common outside of Europe. The best-known form is the NEMA standard, which is not used in Europe (with a few exceptions). NEMA stands for National Electrical Manufacturers Association and describes a whole range of different sockets and power plugs. These are commonplace in America, such as the United States, Mexico, and Canada. Type B (NEMA-5-15) single-phase AC power is most commonly used in the United States. The regular operating voltage is 120 V, the mains frequency is 60 Hz. NEMA-6 series connectors are intended for heavy loads such as electric ovens. The NEMA system is also in use in parts of Asia, including Japan and Thailand, China and the Philippines. In addition, at eibabo® you will find sockets according to British Standard, Swiss Standard or Australian Standard.How do I integrate a standard Schuko socket into the smart home?An existing socket can be easily expanded in terms of functionality using a WLAN socket. As a rule, these are adapter plugs that you plug into the existing socket. These represent a link between the end device and the socket. An associated application (software) enables the connection to the home network. But it doesn't have to be WiFi. Other models use Zigbee, Z-Wave and Bluetooth as radio technology. If your electrical installation is just being planned, we recommend reserving a few sockets for your smart home. Then you have the option of using the corresponding flush-mounted sockets. These look visually appealing like classic sockets. You no longer need an additional adapter plug.Already knew?At the beginning of the electricity age, sockets and light switches were considered status symbols. Those who were self-respecting presented the electrical installation of the house 'surface-mounted' and clearly visible to everyone.The advantages of such sockets are, on the one hand, that the devices connected to the sockets can be disconnected from the power supply quickly and easily via the smart home system. In this way, the devices do not run on standby and save electricity. On the other hand, you can operate the sockets when you are not at home. If such a device is compatible with Apple HomeKit, Google Assistant or Amazon's Alexa, you can use it to control it.What is the difference to a socket with increased contact protection?At first glance, a socket with increased contact protection can hardly be distinguished from a classic socket. Some manufacturers mark such a model with a small symbol on the case.Image: Gira 045327 Schuko socket outlet with child protectionSockets with increased contact protection have an additional internal safety device that can vary depending on the manufacturer. In some models, this consists of rotary vanes. These open when both pins of a connector exert pressure on them at the same time. With other systems, the central insert can be rotated. So no object can be inserted into the holes of the socket. The installation of such sockets is recommended, for example, where children may have access to them. In other wordsThe designation 'Schuko' for protective contact has nothing to do with protection against accidental contact. Protection against accidental contact must also be provided. An alternative to the socket with increased protection against accidental contact can be separate socket protection. These plug into a standard socket and often work with a twist or slide motion as well. It is very safe with socket locks or lockable flaps.Why should I lock an outlet?Sockets are everywhere. These cannot always be monitored. In times of constantly rising energy costs, one often hears about electricity being stolen unnoticed via a hidden socket. This is made particularly easy for thieves if the socket is publicly accessible. Even if animals, children or other vulnerable people are constantly in the immediate vicinity of the socket, we recommend a lock. Lockable sockets or socket locks are available in the eibabo® shop at reasonable prices. Use our intelligent search.Are there sockets for other areas of application?In addition to classic sockets for everyday use, there are sockets in special shapes. You may need sockets in a place where neither a flush-mounted socket nor a surface-mounted socket is possible. A classic example is the junction box. Here you need a socket with mounting options on the DIN rail. Such models are often adapted in width to the pitch units in the junction box. Another special form are the so-called CEE sockets. These are available in the strengths 16 A, 32 A, 63 A and 125 A and are equipped with three to seven pins. Different colors represent the appropriate nominal voltage. The eibabo® shop offers CEE sockets and sockets for the junction box in separate catalogues.

Alarm control panel - Would you like to control and regulate as many functions of your KNX building automation as possible from a central location? Then take a look at our multifunctional alarm control panels. With these convenient control centers, you always have an overview of all the comfort settings, automatisms and security-related parameters integrated in the building network. Read more about the use and function of these devices below.Image: Busch Jaeger 8136/12-811 KNX Comfort PanelWhat is the KNX protocol?In order to be able to understand the full potential of the alarm control panels, you must first know the KNX standard and its possibilities.There is a growing desire for more convenience and versatility in managing the heating, lighting and security of a home or office building. At the same time, the efficient use of energy is becoming increasingly important. People want a comfortable, environmentally friendly and safe environment to live and work in. And this is where automation can make a valuable contribution. More comfort, greater security and at the same time lower power consumption can only be achieved with intelligent controls for all devices involved. However, this is fundamentally a problem, since when implementing such a system, numerous different sensors and actuators must be controlled using different command devices. Furthermore, the large number of cabling means increased construction work and more effort during installation for planners, as well as higher costs for the user. Simplification would require a system that eliminates the problems of isolated devices. And that is KNX. KNX ensures that all components communicate in a common language. It doesn't matter what kind of device you want to use. The functions can be individually adapted to your needs and include, for example:lighting and blindsSecurity systems, alarm and surveillance systemsEnergy management, heating, ventilation, air conditioningremote controlsAudio and video controlsInterfaces to systems for building maintenance and building management All these functions work with the KNX fieldbus for building automation via a single system. All components interact with each other and create a dynamic building control system. With over 500 KNX-compliant manufacturers, flexibility and choice are huge. KNX is thus the global standard for intelligent building control and ensures full compatibility between manufacturers and related products. The KNX system can be used in almost any building or open space - from a small house to a large shopping center or industrial complex.What are KNX annunciator control panels?A KNX annunciator panel and control panel are usually highly complex, room-spanning control devices, infotainment interfaces and entertainment centers. With these devices, the complete control of a KNX building automation can be implemented at a central point.Which controls are possible with alarm control panels?There are countless equipment details for complex, logical functions. These include, among others:switching and dimmingBlind controls and automatisms for shadingroom temperature controlsCentral functions and scene controlsMultimedia, IP telephony, RSS reader, intercom with image, e-mail, voice memo and graphic memoMonitoring of consumption dataDoor communication with integrated camera and proximity sensorVideo surveillance with alarm and reporting function Everything is now possible. More and more KNX manufacturers are also offering direct interfaces to other home automation systems. These include Bang & Olufsen (B&O), Philips, Siemens Logo, Siemens SPS, CoDeSys, Beckhoff, Omron, Mitsubishi and many other systems. The menu structures of the KNX signaling control panels are partly already implemented or completely freely parameterizable.What should I look out for when buying a KNX annunciator control panel?The requirements for operating your building automation can be quite different. Depending on the type and complexity of your system, a simple device may be sufficient or a complex device may be required.Saving TIPIf it is 'only' about basic functions such as dimming, setting blinds or controlling the heating, we recommend our high-quality KNX push-button sensors. These can also be parameterized individually, look smart and are significantly cheaper to buy.This results in some purchase criteria that you can consider when making your choice:What is my budget?Do I need a complex annunciator control panel at all or can I achieve the same result with alternative devices (e.g. a push button sensor)?Which functions do I want to map?What color and design do I like (glass, stainless steel, plastic)?How should it be operated (keys, touch)?Should the bus coupling be integrated?What other interfaces are required?Where and how is the device installed (surface-mounted, flush-mounted)?Do I only need the control element or also mounting material and frame?Should a possible display be in color or is a monochrome variant sufficient?Is a special degree of protection necessary (e.g. for outdoor installation)?and more What should be considered during installation and integration into the home network?The devices are very complex. You should therefore note that commissioning can also be very time-consuming. Integration into a network via KNX IP router (routing & tunneling protocol) or KNX IP interface (tunneling protocol) is often necessary for full functional use, depending on the required protocol. Therefore, please ensure that you also lay a network cable in addition to a 230V AC power supply and the KNX bus cable. designeibabo® offers versions in high-quality stainless steel or with the finest capacitive glass surfaces as well as individual frame designs. This makes these all-rounders an eye-catcher in every multimedia KNX smart home. In this eibabo® catalog you will find high-quality KNX panels, KNX comfort panels, design frames, KNX touch panels, KNX control panels, KNX mini panels, KNX smart panels, KNX glass color displays, KNX LED displays and many other devices for controlling your Attachment.

Luminaire terminal - The hobby do-it-yourselfer needs them and of course the professional at work too, when power cables have to be connected or circuits have to be created. We're talking about lamp terminals. Depending on the region, these little helpers are also called luster terminals, connection terminals or connecting terminals. The term Wago clamp is also widespread, although this represents a specific type of cable clamp and is sold by the company of the same name. Chandelier or lamp terminals are mostly plastic-coated metal tubes that connect two or more cable ends with one another using one or two locking screws. How many cables can be connected depends on the diameter of the tube and how many cable ends can be accommodated in it. Often 10 or 20 tubes are connected together through the plastic so that multiple cables such as neutral, earth and live can be organized together. A classic Wago clamp works in a similar way. However, it works without screws using clamp connections and only two or more cables of the same type can be connected to each other per clamp. In the eibabo shop you will find a large selection of all common light terminal systems.Catalogue content:In this eibabo® catalogue Installation, isolation and connection material > Terminal for luminaire you will find items from the following product groups:Item overview:1-wire clamp1-wire light terminal2-wire clamp2-wire light terminalClampConnection terminalConnectorDoli clampDolu clampDoly clampDouble conductor terminalDouble springInstallation technologyLamp clampLamp clampsLuster terminalsMulti-wire light terminalPlug clampPlug-in terminalPlug-in terminalsPush-in terminal connectionService clampSingle clampSingle conductor terminalTerminal blockTerminal for luminaireWago clampWago clampsfrom the following manufacturers:Manufacturer overview catalogue Luminaire terminal:Hellermann TytonOBOWAGO

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. We have more than 25 years of experience in the field of building automation and have arranged the order of the products in this catalog accordingly.

Cable coding system - The clock is ticking. The sweat of fear is clearly dripping from the forehead of the hero and the heroine. Which is the correct cable that needs to be cut to avert the ominous explosion? Surely you know at least one action film that drives the suspense immeasurably through a scene of this kind. This situation is not only familiar to us from Hollywood, but also from everyday life. A nerve-wracking jumble of cables that wastes time and energy has probably been experienced by everyone. The correct cable marking would not only cause far less stress for the protagonists in the film. Thanks to the extensive range at eibabo, you not only save nerves, time and money, you also invest in your safety. Practical label dispensers for manual labeling are ideal for small-scale maintenance and repair work. Permanent, professional labeling is ensured using a special marking pen. Specially developed cable markers stick to cables and conductors, even under high loads. The identification is protected from environmental influences by a transparent pocket. These two examples are just examples of the wide range of cable marking systems at eibabo.Catalogue content:In this eibabo® catalogue Installation, isolation and connection material > Cable coding system you will find items from the following product groups:Item overview:Cable coding systemCable labeling machineCable labeling systemCable markerCable markersCable marking systemClip-on markerConductor markersConductor markingCore identificationCore identification tapeCore markingIdentification plateIdentification system for cablesIndividual identification plateLabel dispenserLabel sheetLabeling systemLine identificationMarker bookletMarker dispenserMarkers to write on yourselfMarking for cablesPaperback markersPlastic Cable MarkerQuick labeling systemSealTuck-in stripsfrom the following manufacturers:Manufacturer overview catalogue Cable coding system:3MABBCellpackCimcoHellermann TytonLappLegrand BticinoMurrplastikPanduitPhoenixRosenbaumS-ConnectSchneider ElectricWAGOWeidmüller

Toaster - Toasters come in many varieties. The choice for or against a particular model depends on the needs you have for toasting bread. For a single household, a compact one-slice toaster may be sufficient. Two-slot toasters make more sense for couples, and families should go for larger ones that can toast four or more slices of toast at once. You should also pay attention to the length of the slits. If you would like to toast black bread or farmhouse bread from time to time, we recommend a long-slot toaster from the eibabo online shop. Most models also have a bun attachment. With it you can easily give rolls, bagels and croissants the desired bite. This is usually very quick and you save electricity because the large oven does not have to be turned on. The sandwich toasters, which are constructed similar to waffle irons, are a special form. This means that toasted and folded toast slices can be browned from above and below at the same time while the topping heats up or melts.Catalogue content:In this eibabo® catalogue Small domestic appliances > Toaster you will find items from the following product groups:Item overview:2-slice toaster4 slice toaster4-slice toasterBread roll warmerBun bakerBun toasterCold wall toasterCompact toasterElectronic toasterKitchen utensilLong slot toasterMini toasterReversible toasterRoll bakerRotating toasterSandwich makerSandwich toasterSoft lift toasterToast machineToasterToaster/mini ovenToaster/sandwich makerToaster/sandwich toasterToasterSandwich ToasterTwo slot toasterWaffle makerfrom the following manufacturers:Manufacturer overview catalogue Toaster:Beko Grundig SDABomannBomann DABosch HausgeräteBosch SDABraun HausgeräteBraun SDACloerFakir SDAGraefGrundig SDAKrupsMoulinexOmegaPrincessRommelsbacherRowentaRussel HobbsSeverinStebaTefalUnoldVarta Cons.Russell

Cover frames - How do you turn your switches, buttons or sockets into a visual highlight? Are the standard models from the hardware store not individual enough for you? We'll show you how to combine colors, shapes and styles, sometimes across manufacturers. At eibabo® you will find a large selection of cover frames, cover plates, ring plates and central plates as well as intermediate frames from over 40 brand manufacturers.What are cover frames?The cover frame forms the outer ring of a socket, button, switch, controller, network socket or other insert. The manufacturers have adapted to the needs of their customers and produce switch programs with which you can determine the appearance yourself. Cover frames are available for individual inserts, but also for two to eight times. For example, combinations of switches, buttons, sockets and network sockets are possible. Choose between numerous designs, materials and the many variants for vertical or horizontal installation.Can frames and inserts from different switch series be combined?Combine the cover frames in different designs with inserts from other series and manufacturers. This allows you to design switches, sockets or other inserts with different cover frames in your living room in a highly individual way. Or set up your office workstation ergonomically and efficiently according to your ideas.What to look out for:Is the cover frame suitable for a round or square insert?What is the dimension of the inner diameter or cutout?Are the corners of the cutout rounded?Is the cutout square?Does the color of the insert match the color of the frame? PICTURE: Cover frame variants round and square, whiteThis results in the choice of the appropriate insert. Most manufacturers produce frames and cover frames with an inner cut-out of 55x55mm or 50x50mm. This enables you to exchange, combine or vary central inserts such as sockets or switches with frames, regardless of the manufacturer. Refer to the product description to find out whether the inside dimensions of the cover frame you have chosen fit the desired central insert. TIP:White is not the same as white. If you want to combine different white parts from different manufacturers, please make sure that the color and the surface are the same. Slight differences in color and surface gloss between white components quickly appear as incorrect colors. However, deviations do not pose a problem if two contrasting colors are intended to be combined.Are there also cover frames that do not match other series?Of course, there is nothing wrong with choosing a special range of switches from a specific supplier here in the shop. There are numerous cover frames and inserts that only fit the respective counterpart of the special series. Nevertheless, you have the opportunity for individual design, provided the series has color combinations.PICTURE: Cover frame variants - Busch Jaeger Impuls colouredSome manufacturers offer exclusive switch programs. These can be made of brass, stainless steel or brushed aluminium. Cover frames from these series are usually not compatible with other programs either.How do I mount a cover frame?In most cases, the cover frame is clamped behind the central plate (the plastic part of the insert) of the socket, switch or button. This is held securely by screwing the central plate to the insert. If you want to remove the frame, loosen the screw in the middle of the central plate and pull it off carefully. Now you can remove the frame. Please pay attention to your safety, because after removing the covers, the current-carrying contacts are exposed. When working with electricity, please always switch off the power supply beforehand and secure it against being switched on again.Hygienically cleanCentral plates and cover frames are often touched and should be cleaned regularly. Dirty plastic parts can be cleaned again in the dishwasher.Cover frames that are sensitive to heat or water (e.g. metal frames) should be carefully cleaned by hand. Before you begin assembly again, the clean parts must be absolutely dry. Place the frame behind the central plate and screw it to the insert.Do cover frames break easily?Cover frames and central plates are rarely subjected to greater loads. Only during assembly and disassembly is there a risk of damage, for example by overtightening the screw. In everyday life, the high-quality products from all major manufacturers have proven to be very robust.
