Manual wall transmitter - Manufacturers of radio bus systems for home automation systems use different radio standards (EnOcean, Z-Wave, ZigBee, Bluetooth Smart, Bluetooth, WLAN). Leading manufacturers are Eaton Eltako and Thermokon. This catalog offers wireless handheld wall transmitters for different automation systems made by different manufacturers. Radio bus systems are an alternative to building automation systems such as KNX, LON or LCN. Radio bus systems are much cheaper and the range of applications and devices differs from manufacturer to manufacturer. Therefore, one should not use proprietary radio bus systems, but a radio bus system where devices of different manufacturers are compatible, such as with the KNX. However, in radio bus applications, the scope of options is always increasing in order to meet the smart home requirements. Radio bus systems can be connected to building automation systems, for example to KNX. Thus, mixed applications are possible, for example if installations with cables and wires are not possible (glass constructions, wood surfaces, open spaces). Compared to building automation systems, it is easier to put wireless home automation systems into operation and they are cheaper, but they are also less flexible when it comes to complex functionalities and future extensions. eibabo provides battery-free wireless wall transmitters, wireless remote controls, wireless handheld transmitters, handheld KNX radio transmitters, KNX radio wall transmitters, wireless outdoor transmitter module, wireless handheld multi transmitters , KNX RF transmitters, KNX wall transmitter modules, wireless wall transmitter inserts or wireless universal transmitter radio bus from leading radio bus manufacturers such as Berker, Busch Jaeger, Eaton, Elso, Eltako, eQ-3, Gira, Hager, JUNG, Peha, Schalk, Siemens and Thermokon.Catalogue content:In this eibabo® catalogue Installation bus systems > Hand-/wall sensor for bus system you will find items from the following product groups:Item overview:Bus system handheld/wall transmitterBus system wall transmitterBus technologyDouble asterEnd stripsHand-/wall sensor for bus systemInstallation switchManual transmitterMoellerfunkPosition buttonQuad buttonRadio button interfaceRadio remote controlRadio systemRadio transmitterRadio wall transmitter insertRemote controlSingle buttonSolar cellSurface-mounted buttonTransmitter insertTransmitter useTransponderWall transmitterWall transmitter completeWall transmitter insertWall-mounted transmitter completeWall-mounted transmitter insertfrom the following manufacturers:Manufacturer overview catalogue Manual wall transmitter:BerkerBusch JaegerEatonElsoeQ-3GiraHagerJungPehaSchalkSiemens

Sensor blinds-time switches - As part of your building automation, should your blinds react independently to wind speeds or brightness? Then you need wind sensors, brightness sensors or multi-sensors, which determine the required measured values. We would like to explain the functional principle of the most common devices to you below.Sensors for controlling blinds are measured value transmitters for the wind-dependent, light-dependent and time-dependent control of sun protection products. The use of these devices makes the operation of your sun protection systems and shading systems particularly easy and convenient. The sensors react automatically to wind, the position of the sun, rain or other environmental influences and forward the measured values in the form of electrical signals. As specialists for smart home installations, we offer you only high-quality components for your systems in the eibabo® technology store and help you to select the right products.What is a wind sensor?A wind sensor is also known as an anemometer. It is a device for measuring the speed of movement of gases, as well as air in closed systems. In meteorology, the device is used to measure wind speed. Depending on the functional principle, a distinction is made between the following types of anemometers:mechanical wind sensorsthermal wind sensorsacoustic wind sensors TIPInstall a wind sensor as high as possible and free-standing, preferably on a mast at a height of about 10 meters. Dormer windows, house walls or trees influence the measured values and falsify the actual conditions. The mechanical wind sensorIn a mechanical wind sensor, the movement of gas or air causes a windmill or impeller to rotate. This sensitive element is movably mounted on an axis of the device connected to the measuring device. The wind causes the wind wheel to rotate around its own axis and the measuring mechanism records the number of revolutions per unit of time. From this, the speed of the wind is calculated. The wind sensor forwards the information to the connected display devices or command devices. This type of wind sensor has been around for a long time and is still widely used today. The disadvantage of these devices lies in the moving parts. These are subject to a certain amount of wear and tear and can be damaged by objects flying around. As a result, failures or faulty measurement data can occur suddenly or slowly and unnoticed.The thermal wind sensorThe functional principle of thermal anemometers is based on measuring the temperature decrease of a heated body (usually a glowing wire) through gas movement. This means that there are highly sensitive sensors in a probe that measure the temperature and air speed. The sensors work on the principle of convection and measure the removal of heat from a heated surface by a moving medium. Applications are in construction, manufacturing, meteorological stations, underground utilities, and in rooms with industrial air conditioning and ventilation systems.The acoustic wind sensorUltrasonic anemometers are based on the change in the speed of sound in gases or air depending on the speed and direction of the wind. The speed of sound against the wind direction is lower than in still air. With the wind, the speed is higher. An acoustic wind sensor evaluates these speed differences and forwards the values to downstream devices.Image: Warema 623021 sensorWhat other sensors can blinds be controlled with?brightness sensorsLight sensors work with photodetectors that record the amount of daylight at the current time. According to the preset programming, the device responds with the output of an electrical signal. As a rule, this is used to regulate the illuminance inside buildings. However, light sensors also work together with roller shutters, curtains or blinds. When the sun shines, the light sensor signals that the windows should be shaded.precipitation sensorsPrecipitation sensors are devices that record the amount of precipitation over a period of time. Rain, hail, snow and mixed precipitation are measured. Depending on the model, the devices are able to interact with actuators and actuators via a wired and/or wireless connection. This ensures an appropriate and immediate response to changing weather conditions. Rain gauges can be used even in difficult weather conditions, as they are designed to provide accurate readings even in strong winds and other unfavorable factors.multisensorsMultisensors are also offered as environmental sensors, multiple sensors or weather stations. These are wired or radio-capable sensors that record various weather data and thus enable the automatic control of building services. The sensors are equipped with various measurement functions, such as temperature, rain, wind speed, humidity, position of the sun, sun height and/or illuminance.Here you saveMultisensors provide a variety of different data and enable automation based on different measured values. The devices are usually less expensive than the sum of the corresponding individual sensors.A clock is also often integrated. Then automatisms can be regulated not only on the basis of the environmental conditions, but also according to the lapse of time. The measured data serve as the basis for triggering automatic processes and are transmitted to the registered recipients for this purpose. Among other things, blinds can be automatically moved to the sun protection position when the sun is shining brightly. Using additional actuators, lights can also be switched on and off automatically at certain brightness values or shading can be automatically retracted in the event of wind or rain.What should I look out for when buying sensors for my blind automation?If you know what data you want to collect, pay attention to the following criteria when purchasing your sensors:Easy installation and setupNumber and positioning of the sensorsquality and manufacturerConnectivity to your network We carry high-quality sensors from leading global manufacturers such as Berker, Busch Jaeger, Eltako, Gira, Jung, Merten, Rademacher, Schalk, Siemens, Somfy, Theben and Warema.

Installation relay - What is a relay and how does it work? What types of relays are there? Where are relays used? And which relay suits your project best? Here you can learn more about switching and controlling electrical circuits. Installation relays are used in many different applications. You will find relays in domestic electrical installations, in electrical appliances, in commerce and industry, and in vehicles.A look into historyThe first relay was invented by the American J. Henry in 1831 and was based on the electromagnetic principle of operation. Henry used the relay in his university lab as a 'gimmick' to entertain his students. However, it was not yet possible to switch gears. The first switching relay was invented by Samuel Morse in 1837. Morse refined Henry's device and adapted it to transmit signals (the Morse code) down miles of wire. This was also the basis for the telegraph.Did you know that the world's first computer was also built with only relays? It was a development by Konrad Zuse, which was presented in 1941. A lot has happened since then and relays are no longer used in modern computers. Nevertheless, the relay is still an important and popular component in electrical installations today. Think, for example, of switching on and off the lighting in the stairwell. The circuit works regardless of which floor you are on. However, there are numerous other areas of application. That is why different installation relays are also available in the eibabo® shop. Simply browse through our virtual catalogue. You will surely find some high-quality and inexpensive installation relays that arouse your interest.Image: Eltako ER12-110-UC switching relayWhat are relays?Relays are components within electrical installations of all kinds. They are mainly used as circuit breakers and control switches in electrical devices or are used as important components in many control processes. There are numerous types of relays, which differ in detail. The manufacturers develop the devices for special tasks and adjust the triggering characteristics accordingly. Relays that are often bought in this catalog are coupling relays, power relays, switching relays, interface relays, semiconductor relays and many more. The basic operating principle of a relay is to open and close circuits or contacts by reacting to electrical quantities such as current or voltage.How are relays differentiated?Relays are classified according to various criteria. These include:the type of physical inputs to which the relay respondsthe area of application that the relay assumes in control systemsthe structure of the device design and the principle of operationthe switching capacitythe shape and sizeand some others A relay consists of three main elements:entering / entering a valuethe intermediateof execution / actuation by actuator If we look at the type of physical input variable, we distinguish between electrical, thermal, optical, mechanical, magnetic or acoustic relays. NoticeNot all relays work with fixed physical quantities. Differential relays, for example, react to the difference in values. Polarized relays respond to a change in sign of a specific value. The acquisition of the measurand is the primary element of the relay. This converts the input value into another physical quantity. The receiving element can have different designs depending on the purpose of the relay and the nature of the physical quantity. In the case of a latching relay or a voltage relay, the receiving element consists of an electromagnet. In the case of a pressure relay, this can be a membrane or bellows. The sensing element of a level relay is usually a float and so on.The intermediate element compares the input value with the specified limit value of the device and, if it is exceeded, transmits an impulse to the executing actuator.The actuator transmits the pulse from the relay to the working circuits. Each relay basically contains a control circuit and one or more operating circuits. Depending on the type of actuator, the relays are divided into contact relays and contactless relays. Contact relays act on the outgoing circuit with the help of electrical contacts. Their closed or open state allows either full closure or full mechanical break of the work circuit. Contactless relays act on the working circuit by a sudden change in parameters in the control circuit. This is achieved via resistance, capacitance, inductance or a change in voltage level or current level.How does an installation relay work?Depending on the requirement and application, relays are simple or complex. However, the basic functional principle does not differ significantly. In the center is the coil with an iron core. When current flows through the coil, an electric magnetic field builds up. A movable, ferromagnetic armature reacts to this magnetic field and is attracted. This change in position connects two contact springs with each other and the so-called working contacts in the relay close. In this case, the relay acts as a closer. In some designs, so-called break contacts are opened when the magnetic field is created. These are called openers. Combinations of openers and closers are also possible. These are changeover contacts or changeover contacts.Already knew?If the coil of a relay is suddenly de-energized, high voltage peaks can occur. Therefore, depending on the model, resistors or diodes are used to prevent these voltage peaks from flowing back into the control circuit. Sensitive components remain protected.As soon as the coil no longer generates a magnetic field, the armature is returned to its original position by spring force. The make contacts are no longer closed and the break contacts are no longer open.What are Solid State Relays?More and more relay functions are currently being taken over by semiconductor circuits, so-called solid-state relays (SSR). A solid state relay is an electronic device that turns on and off a high power circuit with low voltages. There are no mechanically moving elements in this type of relay. The device consists of:a sensor that responds to an input signala solid-state electronics with high-performance circuitry Solid state relays can be used with both direct current and alternating current. With the help of thyristors and transistors it is possible to switch currents of several hundred amperes. Compared to electromechanical relays, semiconductor relays have a significantly higher switching speed. Solid-state relays are less suitable for switching under short-term overload conditions. Compared to electromechanical relays, solid state relays offer the following advantages:smaller dimensionshigh switching speedsnoiselesspowerfulmore energy efficientspark-free circuitmaintenance freelong lifetimelow sensitivity to adverse conditions What should I look out for when buying an installation relay?In the eibabo® shop there is a huge selection of different relays with numerous specifications. Choosing the right installation relay can be difficult. Before you buy, you should determine the function of your circuit and then define the task of the relay. Then select a suitable relay for your project. Decision criteria include:What kind is the physical input quantity?Will the device be subjected to vibration and shock?Where will the installation take place?Are dust, moisture or temperature fluctuations to be expected?What is the switching voltage and the switching current?Which current magnitudes and voltage magnitudes occur?What is the expected switching frequency?What requirements do I place on the durability of the relay?Are special functions or additional programming required? Notice:When switching active and inductive loads, opening the circuit for the contacts is the most difficult. In this case, arcing occurs, which puts a lot of strain on the contacts. The switching relays offered by eibabo® are high quality, inexpensive, versatile, reliable and universally applicable. The best-known manufacturers in our range are ABB, Doepke, Dold, Eaton, Eberle, Eltako, Finder, Hager, Jung, Schalk, Schneider Electric, Siemens and WAGO.

Blind control - There are many ways to control blinds. Finding the right solution for your facility can be difficult. In this guide, we'll explain what options are available and help you make a purchasing decision. It doesn't matter whether you need a button for your existing control or are planning a blind control with high-end devices: In our online shop we offer you the complete range of products and solutions for your individual project ideas. In the eibabo® shop you will find high-quality products from leading manufacturers such as Peha, Jung, SOMFY, Schalk, Gira, Busch-Jaeger, Berker, Elso, Merten, Siemens, Warema Sonnen, Doepke and Rademacher. TIP:Plan the controls for your blind carefully. The choice of controller type is important and affects the day-to-day operation of your facility. In addition, numerous control options can influence other parameters of your building and its automation. These include, for example:the management of heating, ventilation and coolingthe energy consumptionthe fire protectionthe security systemand some more An intelligently planned and installed blind control contributes to comfort, security and energy efficiency. Connected sensors assume important comfort and safety functions. Some examples:Blinds, roller shutters and awnings can be controlled depending on the light using brightness sensors or twilight sensors.Precipitation sensors and wind sensors can automatically retract or raise awnings or shutters when the weather changes.Sensors for open doors support you in the implementation of lock-out protection. Once you know what you value, you can determine the optimal type of control. Manual control by hand is the simplest variant. This is the cheapest, not very convenient and offers no possibility for automation. With a wired blind control, you have convenient control options using buttons or switches (also with sensor evaluation). If you instead rely on an electronic blind control, you will benefit from time-dependent control options. You can also automate the daily operation of your blinds and shutters or simulate a presence. You can conveniently control your blinds with a blind control via radio. Complex installations can be avoided with wireless solutions. In addition, a radio blind control is an enormous gain in comfort: You can remotely control blinds, roller shutters or awnings with radio control buttons and radio hand-held transmitters.Wired control via switches and buttonsThe classic method of controlling blinds is to connect the motor cable directly to a switch. This gives you the option of moving the system up or down and influencing the opening. There are no other options. With this setup you control a single motor with a switch or button. This contact closure control can also be used for basic hardwired switching. This enables, for example, control via an alarm system, a fire protection installation or a building management system. To control multiple motors, you need to expand the installation.Image: Jung AT 04 WW awning controlThe use of relaysUsing a motor relay (disconnect relay) you can control multiple blinds from one switch. Group controls and individual controls are possible. The number of inputs on a standard relay determines the amount of individual or grouped motors that you can connect to the relay. Other functions are also possible with relays. Some relays have additional inputs. A classic safety function is the fire alarm. A signal on the relay's fire alarm input overrides all other controls. This allows blinds to be opened or closed automatically as soon as a fire alarm is triggered. Some relays are equipped with potential-free contacts for connection to a home automation or building management system.radio controlAlternatively, you can connect a radio remote controlled motor to a power source. Radio-controlled motors can be controlled using wireless wall switches or a remote control. If you want to operate each blind individually, you can use a separate controller for each motor.Electronic blind controlWith motor control via digital building management, you are absolutely flexible. Each motor has its own address within the network, regardless of the type of wiring. This makes your system fit for any adjustment or change in the future. For example, imagine dividing your parents' house into two residential units for the children. This may require some windows to be regrouped. You can easily change the switch positions for these particular blinds in software without having to physically rewire the building. You can use blind control to improve the energy efficiency of the house. In conjunction with sensors on the window, you can, for example, have the blinds opened or closed automatically. This means that daylight can be used optimally and electricity can be saved. The heat conditions caused by solar radiation also fluctuate throughout the day. Use automation to ensure a constant temperature. Use the sensors of a weather station with an astro function to automatically control the position of the sun on the blinds according to your geographical orientation or to ensure the slats are protected against ice.Use digital assistanceThere are numerous building automation devices that are compatible with your blinds and other devices in your home. These can be connected to digital assistants such as Amazon's Alexa, Google Assistant. This makes it possible to control the blinds using voice commands.Another option is to link the blind control with other automatisms in the building. For example, blinds can be closed depending on the activated alarm system or opened in the event of a fire alarm. The possibilities are manifold. All this increases comfort and improves the quality of life.Which blind control components do you recommend?In the eibabo® technology store you get everything you need to implement your individual blind control.

Radio transmitter - Would you like to automate an existing electrical installation at low cost without having to open walls and lay many lines or cables? Do you want to retrofit or expand your smart home? Then both radio transmitters and radio receivers belong on your shopping list. Find out more here about the possibilities that radio transmitters and radio receivers offer you. Radio technology has become an integral part of our everyday life. Think of radio signals, television and mobile phones, the Internet and many other things.WLAN or Wi-Fi?WLAN is a wireless radio network limited to a local area. Wi-Fi is more of a brand name of a consortium of companies (Wi-Fi Alliance). For example, devices labeled 'Wireless Fidelity' receive WiFi.In the field of radio transmitters, there are numerous device types and standards, such as Wi-Fi, Bluetooth, NFC and cellular.What are radio transmitters?A radio transmitter is an electronic device that generates radio waves. In the field of electrical engineering, the device mainly transmits control signals, switching signals, error messages and status messages. In telecommunications, radio transmitters are used to transmit or send data using an antenna. The transmitter converts the information into a high-frequency alternating current, which is radiated from an antenna as radio waves. Already knew?The Solt transmitter of the Hungarian 'Kossuth Rádió' is the most powerful radio transmitter in Europe. The program can be received in the USA and South Asia. Depending on the type of device, the radio waves are emitted in a specific band of the electromagnetic spectrum. The division into bands serves to fulfill a wide variety of communication tasks. This includes the transmission of voice, images or very general data. The transmitter uses the current of its power source to provide alternating current according to its bandwidth in the required wavelength. This is the frequency at which the alternating current changes direction per second. The electromagnetic waves or radio waves are radiated outwards as a weak signal via a carrier medium (e.g. the air) via the antenna. A corresponding receiver reverses this process and amplifies the incoming signal in order to be able to process the actual message or data. A transmitter can be a separate device or an electronic circuit in another device.Image: Eltako FSM61-UC wireless transmitter moduleHow is a radio transmitter structured?A radio transmitter requires an energy source that supplies the device with power and the energy for transmission. An electronic oscillator creates the radio waves and a modulator inserts the actual data into the radio wave. It does this through small variations in the properties of the carrier wave. A high-frequency amplifier increases the power of the signal. This increases the range. And finally, an antenna tuner matches the impedance of the transmitter to that of the antenna. This makes the energy transfer to the antenna efficient and prevents what is known as a 'standing wave' (reflection of the energy from the antenna back to the transmitter).How important are radio transmitters in building automation or the electrical installation?You use radio transmitters when there is no power line or bus line at a certain point in your installation. There you position a radio receiver, which receives the signals from the transmitter and takes over the desired tasks. These can be switching actions and control functions or the display of information. Radio transmitters are therefore an alternative when flexible installations are desired. Radio transmitters are also suitable if you want to retrofit existing analogue installations and device controls. Radio transmitters are a simple and inexpensive solution for home automation and are used to increase living comfort.You can get a large selection of radio transmitters in the eibabo® technology storefor flush mounting (radio transmitter modules, universal transmitter)for operation (radio buttons, KNX remote controls, hand-held transmitters)for control (wireless weather stations, multiple wall switches, room temperature controllers, wireless window contacts and other sensors) from all well-known manufacturers. These include top brands such as SOMFY, Rademacher, Warema Sonnen, Eltako, Schalk, Sommer and Jung. You will also receive devices and accessories from Hager, Eberle Controls, Berner Torantriebe and EVN Lichttechnik. We also offer elegant wall transmitters that are suitable for flexible installation on wallpaper, glass, mirrors, tiles or wood. Or you can select immediately functional wireless motion detectors, wireless switches or wireless sets from our range.What is the range of radio transmitters in electrical engineering?The range of radio transmitters can vary greatly. This depends both on the radio technology used and on the environmental conditions. Ranges between 20 meters and one kilometer are usually specified. The specifications in the product information about the maximum range are usually values under optimal conditions. These exist when there is a direct line of sight between the transmitter and receiver without obstacles and the area is not affected by interference signals from the same or a neighboring frequency band. Please keep in mind that these conditions rarely apply and the range will therefore be lower in practice. TIP:When installing radio transmitters, allow for a range reserve of 25%. The reserve is not only used to compensate for a lower range due to current obstacles. If further obstacles are added later (e.g. additional walls or growing trees), the devices can still be used.What is an I/O radio module?I/O radio modules are so-called transceivers, a combination of transmitter and receiver. These therefore have signal inputs and signal outputs. This makes it possible to control or monitor systems with just one radio link. In addition to digital interfaces, some models also offer analog inputs for transmitting sensor values and limit values.What do I have to consider when buying radio transmitters?If you want to use radio transmitters, you need additional receivers that pick up the signals, process them and react accordingly. This can be, for example, switching actuators, universal displays or radio-controlled sockets. To ensure that communication between transmitter and receiver works, all components are parameterized using the standardized 'Engineering Tool Software (ETS)'. In this way, each device knows under which conditions it should send or receive commands and how it has to react to changes. The ETS software is available from www.knx.org and is a tool that you need to commission and link KNX devices. Don't worry: programming skills are not required. The ETS is also suitable for laypersons who are interested in the logic of the KNX. Please make sure that your radio transmitter can take over the transmission tasks you want and carry them out correctly. We therefore recommend that you carefully check the parameters and functions for the ETS provided by the manufacturer before purchasing.
