Radio - Radio is still one of the most used media worldwide. It provides entertainment in the office or runs casually on the construction site. But even at home, the radio is an integral part of our everyday lives. In addition to the classic portable radios with CD players and clock radios, you can get them here in the eibabo® online shop:robust construction site radios that can withstand dirt and impactelegant and discreet flush-mounted radio components for your smart home installationportable radio recorders for children's rooms, teenagers' rooms or hobby roomsDAB+ digital radios and clock radios for the kitchen and bathroom Image: Makita DMR301 battery construction site radioWhat are construction site radios?Not everyone is lucky enough to be able to sit in a quiet office and listen to the radio. Many of us are on construction sites every day - road construction and civil engineering, building houses or other locations. But that doesn't mean you have to give up music. Because with entertaining rhythms, time flies by and work is easier to do. But a shell of a house, a metal workshop or the cab of an excavator are harsh environments for a radio. Dust, moisture, paint, glowing chips or impacts can quickly destroy the sensitive technology or damage the housing. But there are construction site radios for such locations. These are designed to be particularly robust and withstand the usual conditions that can occur during transport, in a workshop or on a construction site. Construction site radios are either operated with normal mains power, with standard batteries or in some cases even with compatible battery packs for cordless power tools. This makes the devices very flexible, so that they can also work outdoors on a remote construction site. Depending on the model, there are construction site radios with interfaces for connecting or with the option of wirelessly connecting external devices.A construction site radio differs from a standard radio in its robust construction. These feature protective reinforcements ranging from simple edge protectors to armor-like casings to full exoskeleton-like structures. All of this provides the protection you need should the radio fall down or bang around in the cargo area of the van. High weightDue to their construction, construction site radios are often comparatively heavy. Larger models can weigh over 10 kilograms. To facilitate portability, construction site radios usually have sturdy carrying handles. Typically, construction site radios offer separate buttons for on/off, function selection, radio setting and time display. The buttons and knobs are often rubberized and large so that they can be operated comfortably even with gloves. Some models have a dedicated mute button that allows you to quickly turn off the sound. This is very useful when the phone rings, for example.In addition to tuning in to your favorite radio broadcasts, many construction site radios can be fed via the appropriate interfaces from an additional device such as an MP3 player, smartphone, tablet or CD player. Sometimes even a docking station for the smartphone is integrated. The slots for SD memory cards or USB sticks can usually be closed with rubber covers. Of course, the connection is often also possible wirelessly via Bluetooth. In order to accommodate and protect the additional devices mentioned, many construction site radios offer built-in compartments including interfaces for connection. This is particularly useful when the radio is connected to the mains and you want to use it to charge your mobile phone.What are flush-mounted radios for Smart Home?The modern Smart Home building automation stands for the interaction of entertainment electronics, lighting technology and air conditioning technology as well as security systems. Their use can:save energySignificantly increase the protection of a residential building, commercial or storage areaimprove living comfort and conditions at work In the field of consumer electronics, the eibabo® shop offers you discreet, digital flush-mounted radios that can be easily integrated into your system, controlled centrally or decentrally and connected to the Internet via interfaces. This means that every family member has the opportunity to listen to their favorite tunes, radio plays, podcasts or foreign language courses according to their individual taste. Alternatively, the same music plays throughout the house.What is special about the flush-mounted radios is their size and shape. The devices, like the corresponding loudspeakers, are integrated into switch boxes. As a result, they fit almost invisibly into the house installation and offer networked home entertainment at the highest level. Of course, connectivity is also a key aspect here. External devices can be connected to the radios via Bluetooth.What does digital radio and DAB+ mean?Enjoy your favorite music at home anytime or stay informed by news and podcasts. But what is digital radio anyway and how does it differ from classic analogue radio?Digital Audio Broadcasting (DAB) is a technology that broadcasts digital radio programs. The idea of digital radio came at the end of the 1980s when there were no longer enough free slots for all stations in the regular VHF band. DAB was developed as a digital standard in which more stations can be placed through more efficient coding. DAB has therefore been around for a very long time. The first DAB station was launched in 1995 and the first DAB+ station started broadcasting in 2007. DAB technology is currently used mainly in Europe and differs from analog FM radio in that it can be received anywhere.There are of course technical differences between DAB+ and the usual FM. With VHF, each transmitter transmits independently via radio waves, the range of which is limited. The reception is therefore dependent on the location and the set reception frequency. No radio waves are sent with DAB+. The transmitted digital signals are combined into so-called data frames. Various frequency channels are provided so that different countries can select those which are free from other services. It is thus comparable to the television program, where you can switch between the channels without having to first tune to a specific wavelength. In the past, the transmitters themselves received a license for one frequency for analogue broadcasting. Nowadays, the license is given to a data frame operator and they lease the channels to the radio stations. That is why DAB also has a disadvantage for the listener. The rental of a channel depends on the bit rate of the transmission. So it is cheaper to send with a low transmission rate than with a high one. Thus, as a rule, the optimal or best possible quality is not broadcast.Who Invented the Radio?Finally, a small digression into the history of radio. Heinrich Hertz's proof of the existence of electromagnetic waves formed the basis for the later development of radio. But before the technology was used for entertainment, it was used for the wireless transmission of radio telegrams in the form of Morse code signals.Already knewIn 1899, a radio signal was used for the first time to save people from death. It was a group of fishermen floating on an ice floe near the island of Gotland.The invention of the radio is thus a continuous further development of radio technology, on which Heinrich Hertz, Nicola Tesla, Guglielmo Marconi, Oliver Lodge and Alexander Popov researched separately and independently between 1890 and 1905. So there is no forefather of radio. Each of these scientists contributed to it.We deliver construction site radios, smart home flush-mounted radios, travel radios, clock radios, world receivers and kitchen radios to you worldwide.

Combi i/o device - Combi IO devices are essential components of complex building automation. Find out here how to use the high-quality IO devices and what options there are for your installation. In any case, these devices increase the efficiency of your installation. Learn more about these modules and why it is so important for them to work properly.What is an IO device?An IO device - also known as an input-output module - enables communication between a computer system and a peripheral device. This type of processor communication between devices increases a computer's capabilities. The operating system is enabled to connect to the outside world. Communication and interaction takes place through sending and receiving information. Possible input information are, for example, signals from user inputs or binary inputs. Output signals are sent by the system or converted into actions as manipulated variables by actuators. With the use of a multifunctional input module, the work can be carried out more efficiently and accurately. Typical IO devices include:KNX universal interfacesKNX universal controllerKNX switching actuators with integrated binary inputsKNX button interfaces with outputs for LED controlspecial KNX room controller with a variety of special functions  TIP:An IO device can interface with a large number of bus protocols, for example PC Cards, USB, PCI, VMEbus and FireWire. In this eibabo® category you will find, for example, KNX devices with multiple functions from top manufacturers such as ABB, Berker, Busch-Jaeger, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens and Theben.What are the most important functions of an IO device?An IO device is an essential link in the control chain and closes the gap between your computer system and the external devices. It can perform multiple functions including:Communication between the devices in the systemAn IO device assumes several functions within the scope of device communication. This includes the transmission of status messages, the sending of commands and the transmission of information.communication to the processorFull communication with the processor includes recognizing its own IP address, decoding and accepting commands, and reporting status updates.error managementAn IO device detects different types of problems that can occur between the computer system and a peripheral device. These can be mechanical problems, such as a used printer cartridge or errors that occur during data transfer.Image: ABB IO actuator 8-fold IO/S8.6.1.1timingIn order to be able to correctly manage the flow of information between the system and the external device as part of time management, the IO device accesses the internal resources of a computer.data bufferingOne of the most important functions of an IO device is managing the transmission speed between memory, processor and other external devices.How and where can IO devices be mounted?There are many options for mounting IO devices and they depend on your existing installation. Choose from the following options:Panel mounting - the unit is bolted to a chassis or attached to a panelRack mounting - the device fits into a standard housing, such as a 19-inch rack or similarInstallation on DIN rails - the device is attached to one of the common DIN rails or G-railsfree installation - the device has a stable housing and is set up in a freely selectable placePrinted circuit board assembly - the device plugs directly into computers or is attached to the case What advantages do IO devices offer?Depending on the IO device involved, each can play a significant role within an effective operating system. In a programmable logic controller (PLC) and other operating systems, these devices offer the following advantages:a compact design saves space in almost any assembly environmentthe installation can be done remotelyHardware and associated costs can be savedthe wiring and cable setup is simple and clear What are the properties of the inputs and outputs on the IO devices?As a rule, IO devices offer digital channels, analog channels or a combination of both variants. The digital inputs and outputs handle low-level on-off signals. Analog inputs recognize signals such as current, voltage or frequency. Devices with combined channels often process the signals using analog-to-digital converters.The input channels of a device are differentiated as single-ended (SE) or differential (DI). Single-ended inputs consist of two contacts, one of which carries a voltage. The other is connected to ground. Such installation is simpler and cheaper than differential signaling. However, the inductance of the signal line and the difference in ground voltage between the transmitter and receiver will cause noise interference. Differential communication uses two mutual signals on two paired contacts. The difference between the two signals represents the meaningful signal value. Common-mode rejection prevents noise interference. Differential inputs respond to the voltage difference between the two contacts. These are therefore suitable for low-voltage, long-distance and high-resolution applications. The type of input channels your device has can usually be found in the product description. For example, if you have a 16SE-8DI device, it offers 16 single-ended and 8 differential inputs.isolationCertain areas of the electrical system can be isolated from others. This avoids unwanted current flow or signal flow between the areas.For isolation, please distinguish between channel-to-channel isolation, isolated analog input, isolated analog output, isolated digital input, and isolated digital output.  Catalogue content:In this eibabo® catalogue Installation bus systems > I/O device for bus system you will find items from the following product groups:Item overview:Blind controlCentralAccessControl deviceControl elementControl panelControl unitDrive elementDriver moduleEngine control unitHeating actuatorHome serverInput moduleInterfaceJunction boxLight actuatorMixing moduleMulti-controllerOutdoor areaRadio systemSecurity adapterShutter actuatorSmartphoneSun protection actuatorSwitching actuatorSwitching outputUniversal interfaceWireless solutionWireless switching outputfrom the following manufacturers:Manufacturer overview catalogue Combi i/o device:ABBBusch JaegerGiraHagerLingg & JankeMetzSiedleSomfyWaremaWindowMaster
Actuating drive - Do you want your heating systems to offer the desired living comfort while working efficiently? Then it should be equipped with durable and high-quality actuators that optimally control the flow of the heating medium. Find out more about actuators, their function and use here. Actuators are required to open and close the water circuit of a heating system or cooling ceiling. To do this, the drives are screwed or snapped onto a valve. Efficient heating of buildings has become a challenge. It is no longer just about warming the residents, but:adjust the temperature sensibly to the function of the roomusing as few resources as possibleto ensure a long service life of the systemto enable convenient operation All of these lead to money savings, environmental protection and a better quality of life, and depend in part on the heating system installed in the building. In this eibabo® catalog you will find conventional actuators for 24 volt systems or 230 volt systems. Depending on your needs, choose normally open or normally closed models and installation accessories.What are thermoelectric actuators?Thermoelectric actuators are general purpose actuators designed to provide on-off control of a variety of control valves. In private use, these are typically the valves of underfloor heating, but can also be used in industry for other heating systems, ventilation systems and cooling systems. The devices regulate the flow of the heating medium (e.g. hot water) in a circuit and thus ensure that the temperature in the building is controlled. Thermoelectric actuators can be used on the heater valves as well as in the heater manifolds and the floor manifolds.Please noteSome actuator models only suitable for certain valve inserts. Please read the product descriptions and pay particular attention to the dimensioning of the attachment on the valves and the type of power supply.Modern actuators work together with room thermostats and heating actuators and can be integrated into the building management system.Should I buy normally open or normally closed actuators?With actuators, we distinguish between NC (normally closed) and NO (normally open). Which variant you choose depends on your personal needs. NC drives are always closed and open when power is applied. In the case of normally open NO actuators, the current ensures that the valve closes. Please take this into account when planning your heating system. But what are the advantages or disadvantages? In the event of a power failure or defect, NC drives close. If it is a heating season, you will quickly notice the malfunction. It's getting cold in the house. NC drives therefore only consume electricity when they are being heated. On the other hand, drives that open without current are more efficient during the heating period. However, in the warm season you must keep the drives closed using electricity, otherwise you may heat your building unnecessarily. In such a case, switching off the pump by the heating actuator or manually after the winter season would be advisable.How are thermoelectric actuators installed?Thermoelectric actuators (valve drives) are snapped or screwed directly onto the upper part of the valve used in the house. This connection with the valve spindle is usually made directly in the heating circuit distributor. You can use adapters made of PVC or metal to compensate for the manufacturer-specific distance differences between the drive and the upper part of the valve or the thread and the mount. In this way you ensure correct implementation of the manipulated variable.Why are there no KNX actuators?With a decentralized installation, for example in the heating circuit distributor, you can use heating actuators with L and N connections for direct connection of the actuators. You can find more information in our 'Heating actuator' category. Contrary to widespread opinion, thermoelectric actuators are not wear-free and must be replaced every year. This is why earlier versions of expensive KNX actuators (i.e. devices that combine the KNX actuator and actuator) have not caught on and are increasingly disappearing from the market. It is therefore a question of long-term cost efficiency to separate the technology from the positioning drive and the actuator. The actuator is parameterized using the Engineering Tool Software ETS. TIPThe ETS parameter 'Flush' helps to minimize wear on rarely used valves. This function prevents the heating valves from calcifying too quickly. This KNX software is manufacturer-independent and is required to develop and configure individual controls for building automation. That means: The actuator opens and closes the actuators according to the programmed specifications.What should I look out for when buying an actuator?Reliable working actuators are the key to the correct and efficient operation of the entire heating system. When selecting thermoelectric actuators, you should pay attention to the following points:The drives must be compatible with the rest of the heating system. Check that these match the valves. An important parameter here is the so-called stroke, which is usually specified in millimeters. The stroke of the actuator must match the closing dimension of the valve. If the stroke is too small, the actuator will not fully open or close the valve (depending on the NO or NC variant).Decide on a normally open or normally closed variant.Pay attention to the power supply. Here we distinguish between 24 volts and 230 volts.The power consumption of the drive should be as low as possible and not exceed 5 watts.Opening and closing a valve takes time. High-quality equipment offers opening and closing times of less than 3 minutes.The actuator should have an easily recognizable status display so that the current status can be easily read. Image: ABB TSA/K 230.2 thermoelectric actuatorIn addition to thermoelectric actuators, we offer you the following products:radiator valve drivesActuators including binary inputselectromotive actuatorsRadiator control drivesWireless actuators with and without room temperature controllerRadiator thermostatsstraight valvesvalve adapterReceiver for heating actuatorsand many more Well-known brand manufacturers in our range include ABB, Busch-Jäger, Eaton, Gira, Hager, Heimeier, Issendorf, Lingg & Janke, Merten, MDT, Siemens, Somfy and Theben.  Catalogue content:In this eibabo® catalogue Installation bus systems > Actuating drive for bus system you will find items from the following product groups:Item overview:ActuatorBattery poweredBus technologyContinuous controlControl valveEnergy efficientHeater driveHeating controlHeating controllerHeating technologyRadiator thermostatRetrofitRoom temperature controllerRoom thermostatTemperature controlTemperature controllerThermostatTime profileValve driveWax cartridge drivefrom the following manufacturers:Manufacturer overview catalogue Actuating drive:ABBAVM ComputersystemeBusch JaegerEberleEltakoFKRGiraHagerIssendorffJungMertenRademacherSiemensSomfyThebenWindowMaster
