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.

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.

Smart Home - Smart Home is a general term for automation solutions in residential buildings designed to create added value for the user by increasing the quality of living and quality of life. A wide variety of systems and installation procedures are used. Only a few of them are standardized worldwide, e.g. the KNX®, unfortunately most are stand-alone solutions. The devices used for this purpose ought to be compatible among themselves and among manufacturers in order to implement convenience functions, safety functions and energy-saving functions. Human nature is ill-equipped to process the future information overload and extreme rapidity of changes. The human body needs to slow down to be able to consciously perceive its environment and to process and store experiences. This also presents future challenges for manufacturers and service providers of smart home systems, namely to provide relieve to human beings, instead of burdening them with information and instructions. It is very difficult to keep up with the number of automation solutions in the Smart Home field, and the number of actually totally senseless applications is constantly increasing. The consumer can hardly even recognize which hardware and application is smart and which isn't, as nearly everything is advertised as being ''smart'' without actually being so. Who really needs a toothbrush that tells you whether you've brushed your upper left row of teeth long enough, an app-controlled toilet flush or a washing machine that reorders the washing detergent. Applications are only smart if they actually provide the user with practical added value. Studies have shown that most users (over 50%) would like to have a smart heating control, followed by a remote-control window/shutter/rolling shutter control and automated lighting. Of course, the future advances at a rapid speed, and today's standards may already be obsolete 10 years from now and might be replaced by disruptive technologies. The heavy automation of processes and routines, pressure towards efficiency due to globalization, along with massive digitalization in all areas of life are the heralds of a new future. Robot technology and androids will be a ubiquitous part of all our lives in less than 20 years. There are already efforts to optimize the human brain to withstand the future?s heavily increasing challenges of the digital world. Normal life and work routines as they largely exist today will change significantly. There is a substantial future in store for the smart home ? in particular the KNX smart home ? in the private domain, which is why anyone who is planning to build or is currently building a home ought to be aware of the future requirements and at least make preparations now for relevant KNX installations. In our main Smart Home catalogues at eibabo®, we carry a vast selection of products from ABB, Berker, Busch Jaeger, Eaton Moeller, EIBMARKT, ELSNER, EMU-ELEKTRONIK, ESYLUX, Issendorf, GIRA, Hager, Jung, Legrand, Lingg & Janke, MDT, Merten, Siemens, SOMFY, Steinel, THEBEN, Thermokon and Warema available for private and commercial customers at top prices with worldwide delivery.

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.
