Energy management - This catalogue offers articles used for energy measurement or energy optimization in various bus systems, for example for radio bus system applications or the KNX bus system. KNX energy meters can be used for utility cost billing or cost monitoring, for cost center billing, energy optimization, visualization or installation monitoring. These KNX meters do not only capture and display consumption values, they also display other functions. They can be used to identify high consumption devices, to switch off specific channels if thresholds are exceeded or just to display the daily energy costs, voltage, current and power data. KNX visualization can generate a variety of display formats depending on time or load profile, can store your energy provider?s current prices and display accrued costs and compare them. For billing purposes, the meter should absolutely be calibrated and have MID approval. MID means Measuring Instruments Directive. The MID is a EU directive covering measuring instruments. Even in case of bus failure, the meters should continue to collect and store data. All KNX meters can be ordered as calibrated or uncalibrated type and with / without MID certificate. In Germany, for example, electricity meters used commercially must be calibrated. Therefore, check whether the meter intended for commercial application can be used in your country. After expiration of the calibration period (8 years for electronic meters, 12 years for mechanical transducer meters with induction system or 16 years for mechanical meters with induction system), the meter has to be replaced or the calibration period extended. Carefully study the features and parameters of the meters provided by different manufacturers to find the most suitable meter. There are different types of KNX meters, for example, direct meters or transformer meters for very high currents. In single-family houses or apartment buildings KNX direct meters are generally used. These are usually available up to 100A. In this eibabo category you will find, for example, radio single-phase meters, KNX energy meters, interface modules, energy measurement sensors, KNX power modules, KNX sensors, KNX meter interfaces, wireless energy sensors, KNX peak load limiters, bus electricity meters of the brands ABB, Busch-Jäger , Eaton, Eltako, Gira, Hager, Lingg & Janke, Merten and Siemens for various automation systems.Catalogue content:In this eibabo® catalogue Installation bus systems > Energy management for bus system you will find items from the following product groups:Item overview:5-level maximum guardBus systemBus system energy managementConsumption meterDIN rail counterDirect/ConverterDirect/transformerEIBElectricity meterEnergy counterEnergy efficientEnergy management for bus systemEnergy measurementEnergy meterEnergy visualizationInput moduleMaximum demand monitor for distribution boardMaximum guardMaximum GuardianMaximum monitorMaximum monitoringMeter scannerMoellerfunkPeak load monitoringSwitching actuatorThree-phase meterTransducer measurementTransmitter modulefrom the following manufacturers:Manufacturer overview catalogue Energy management:ABBEatonEltakoGiraHagerJungKOSTAL SolarElectricLingg & JankeMertenSchneider Electric
Current limiter - Various devices for current limitation are available in the eibabo online shop. But what are these devices used for? Inrush current limiters or starting current limiters are often used when motor-driven devices and machines are used, but these have a very high power consumption when switched on. Under certain circumstances, this can trigger a voltage peak that is several times the secured nominal current. Especially in buildings with older electrical installations, this can lead to overloading of the power grid. A starting current limiter is therefore installed between the device and the house electricity and automatically reduces the load on the mains when the device is switched on. There are also high-quality current-limiting relays in the range, which, for example, regulate the load on the mains in larger installations with fluorescent lamps or in lights with ballasts. These installations can be further protected by using motor protection switches or safety temperature limiters.Catalogue content:In this eibabo® catalogue Low-voltage industrial components > Current limiter you will find items from the following product groups:Item overview:Circuit breakerContact protectionControl unit for halogen lampCurrent limiterCurrent limiter for motor protection switchCurrent limiters for transformersCurrent monitor for LV halogen lampCurrent monitoring device for transformersElectric arcEngine managementEngine outputEngine protectionEngine starterGuardianInrush current limiterLow-voltage halogen current monitorLV halogen current monitorMeasuring relayMotor centerMotor contactorMotor protection switchOverload protectionPower guardPower triggerService centerShort circuit protectionShort-circuit current limiterStarting current limiterfrom the following manufacturers:Manufacturer overview catalogue Current limiter:BachmannBlockEatonEltakoGiraIsmetSchabusSchalkSchneider Electric
Motion detector sensor - Our eibabo catalogs of motion sensors offers a wide range of motion detectors and sensors for surface mounting and flush mounting. In addition to motion detector sensors, we also provide add-on automatic switches and automatic switches, surface switches, motion detectors, ceiling detectors and ceiling presence detectors, BLC and IR switches, Busch-detectors, wireless motion-brightness sensors, wireless detectors and wireless alarm panels, IR motion detectors, presence sensor modules and sensor modules with switches and detector sensors. Motion detector sensors are electronic sensors that detect movements in the immediate vicinity and can be used as electric switch. Thus, you can use motion detectors to turn on your lights or to trigger an alarm system. To detect movement, motion detector sensors either work actively with electromagnetic waves (high frequency or Doppler radar) or ultrasound (ultrasonic motion detector) or they operate passively by means of the infrared radiation of the environment. Some motion sensors are also available as a combination of active and passive design. Power consumption of most commercially available motion sensors is typically less than 1 W. Note that there is a reactive power of the capacitor power supply. Infrared motion detector sensors are the most common types of motion detectors. These sensors respond to changes in the ambient temperature, for example, people who pass close to the sensor. Motion detectors that work with Doppler radar or high frequency sensors respond well if the distance of moving objects to the sensor changes.Catalogue content:In this eibabo® catalogue Domestic switching devices > Sensor element for movement sensor you will find items from the following product groups:Item overview:Automatic switch attachmentAutomatic switch sensorComfort attachmentGuardianInfrared detectorInfrared motion sensorInterior detectorIntruder alarmMotion detection systemMotion detectorMotion detector intrusion detection systemMotion Detector SensorMotion detector wireless alarm systemMotion sensorMovement sensorPresence detectorRoom MonitorSensorSensor attachmentSensor element for movement sensorSensor element for movement sensor basic elementSentinel System SensorStandard attachmentSystem guardSystem motion detectorSystem movement sensorSystem sensorWireless motion detectorfrom the following manufacturers:Manufacturer overview catalogue Motion detector sensor:BerkerBusch JaegerElsoEltakoESYLUXGiraHagerJungLEDVANCEMertenPehaRademacherRidi-LeuchtenSchneider ElectricSiemensSomfySteinelTheben
Insulation monitoring device - How does an insulation monitoring device work and where do I have to use it? What does the device protect against and what advantages does it offer me? Read here why the correct insulation of an electrical system is an essential prerequisite for its safe operation. Protect yourself and your system with high-quality measuring devices and reliable testing technology from the eibabo® online shop.The History of Insulation Monitoring DevicesThe first insulation monitoring device was invented by Walther Hans Bender in Frankfurt/Oder in 1939 and a patent was applied for. It was a device for three-phase systems in brown coal mining. In 1952 the 'Isometer' was protected as a trademark and has belonged to Bender GmbH & Co. KG ever since.Image: Dold IL5880.12 insulation monitorHow does an insulation monitoring device work?An insulation monitoring device is also referred to as a ground fault monitoring device. Connect this between your active power lines and the earth line. With continuous insulation monitoring, you can discover weak points in the insulation of your electrical systems. These can be caused, among other things, by moisture or by age-related fatigue of the material. You want to detect a problem like this before voltage breakdown occurs. Voltage breakdown will damage the insulator and cause sparks or arcing, which can lead to power failures, fires, property damage, and personal injury.The device sends a measuring voltage to your system and monitors it. If there is a ground fault, the measuring circuit between the mains line and the ground is closed. A measuring current proportional to the earth fault thus occurs. A voltage drop occurs at the measuring resistor of the device. Conversely, this means that the insulation resistance of the system is reduced. The insulation monitor registers the change and evaluates it. It is not only the resistance itself that is important, but also its course over time. In the case of undamaged insulation, the insulation resistance asymptotically approaches a certain reference value. term asymptoteA value behaves asymptotically if, over time, it approaches a reference value without ever reaching it. If the insulation resistance falls below the reference value, this is an indication of the increase in the conductivity of the insulator. From this it can be concluded that the insulator has changed chemically due to external influences or that its material is gradually enriched with decomposition substances. If a critical point is reached, the device sends a message. This allows you to recognize the deterioration of the technical condition of the insulation at an early stage and to take the appropriate steps for repair or maintenance in good time.Where is the use of an insulation monitoring device required?The measurement of the insulation resistance is used in local low-voltage networks without an operationally grounded star point (so-called IT power supplies).For explanationBasically, low-voltage systems are divided into TN systems, TT systems and IT systems. The main difference lies in the way of grounding. While residual current is used for monitoring in TN systems, insulation monitoring devices are used in IT systems.Modern insulation monitoring devices have a history memory and record the insulation resistance measurements. The data can be called up later and serve as suitable monitoring evidence during controls.What are the advantages of insulation monitoring devices?With insulation monitoring devices, you continuously monitor safety-relevant circuits for residual currents and residual currents. This results in a number of advantages in daily use:Measurement without switching off ongoing operationsReducing the risk of failure and increasing the availability of monitored electrical systemsReduction of electromagnetic interferenceReducing the risk of fireSaving of time-consuming and expensive maintenance and repairs You also prevent the safety of people and machines and thus avoid accidents, property damage and personal injury.Which manufacturers offer high-quality and reliable insulation monitoring devices?In the eibabo® technology store you only get quality goods from well-known manufacturers.

Motion detector - What are the differences between KNX motion detectors and KNX presence detectors? And how do I know which devices are the right ones for my application? We describe what you should look out for when buying a motion detector and provide you with useful information on use and installation in the following article.How do you differentiate between KNX presence detectors and KNX motion detectors?A basic distinction is made between KNX presence detectors and KNX motion detectors in the conventional area or in home and building automation, whereby presence detectors can usually also be used as motion detectors and are therefore often the better choice.The differences and main advantages of a presence detector compared to a motion detector (simplest light measurement, interference from artificial light) are the variable usage options due to the special and permanent light measurement (daylight and/or mixed light), even during the switch-on process. The light value is measured with a special sensor, which has a spectral sensitivity similar to that of the human eye. TIP:For outdoor use, use motion detectors that have several function blocks in the sensor technology in order to control independently of the brightness and/or depending on the brightness. So the typical difference lies in the application. A KNX motion detector is used to switch on when motion is detected and the purpose of a KNX presence detector is to switch consumers on or off when no more movement is detected or a brightness limit has been exceeded in order to save energy. An exemplary application would be in a toilet. Here I would like during the day that the lighting is not activated when there is sufficient brightness. This is realized by the motion detector function. However, the fan should switch on with the presence. If the brightness is insufficient, both should of course be switched on. This function is often enabled by presence detectors that have several channels. The motion detector channel is used brightness-controlled for switching lighting and the presence detector channel for brightness-independent switching of other consumers, such as a fan.Which areas of application are typical for the respective KNX presence detectors and KNX motion detectors?The complex sensor technology in a presence detector can detect sensitive movements, which are particularly typical for office workplace applications or workplaces. A motion detector is used in small rooms, bathrooms, storage rooms, garages, corridors, stairwells or for monitoring outdoor areas.What function can KNX detectors take on?Both indoor and outdoor versions naturally have a wide range of parameters for switching or dimming lighting, moving blinds or shutters, applications for heating, air conditioning and ventilation, master/slave functions, blocking operation functions, logic functions, functions for pets (animal lane), detector operation for Alarm systems with other sensitivity modes, sneak-by protection, rear field surveillance, stairwell surveillance, constant light controls and much more.Image: Theben theLuxa P300 KNX WH outdoor motion detectorMultiple channels are often provided to control individual functions.What questions should you ask yourself before you buy?Is the installation indoors or outdoors?What should the detector react to?Which area should be monitored?What actions should the detector take?For what performance must the device be designed?What lines and cables are there or need to be re-laid?and much more Where should a KNX motion detector or KNX presence detector be installed?The detection areas and the necessary mounting heights can vary greatly and should be selected appropriately for the required application. NOTE:The higher the mounting height, the greater the range of the device, but the sensitivity decreases. If the area to be monitored is too large, it is advisable to use additional detectors to ensure complete presence detection. In any case, sources of interference must be avoided in order to ensure proper functioning of the device and to rule out false signals. This includes not only objects that obstruct the view, but also dazzling light sources or objects that can quickly change the temperature of the detection area.the right angleDepending on the model, presence detectors and motion detectors detect a specific area of the environment. The spectrum ranges from very close and targeted monitoring to 360° detection.When making your selection, also pay attention to whether a motion detector will be exposed to the weather. In these cases, choose a waterproof device and clean the sensor regularly.Why is my KNX presence detector not working properly?Proper functioning depends on various factors. Assuming that the installation has been carried out correctly, the most common malfunctions are that the detection area is not set optimally. Either the direction is wrong, the angle of detection or the distance is too small or too large, or the device itself is not suitable for the corresponding area of application.The fewer movements to be expected in the monitored area, the longer you should choose the run-on time. Because as soon as a detector detects a movement, the follow-up time is restarted again and again.Are there KNX motion detectors or KNX presence detectors with special properties?Yes, in the eibabo® technology store you can get detectors for many different applications. Depending on your requirements, you can choose, for example, from classic KNX motion detectors for outside or inside, KNX presence detectors, KNX guards, KNX passive infrared motion detectors, KNX PIR detectors, KNX presence detector interfaces, KNX detectors with high-frequency sensor technology, KNX ceiling presence detectors, KNX wall presence detectors, KNX automatic switches , KNX automatic top units, radio bus motion detectors, KNX radio solar motion detectors, KNX corridor presence detectors, KNX comfort presence detectors, KNX presence detectors with constant light control, KNX guard sensors, KNX presence detectors with DALI, KNX radio motion detectors, KNX radio guards or KNX IR presence detectors Plus. Each of these models has its own strengths and is optimized for individual applications.What is a passive infrared motion detector?Passive infrared motion detectors (PIR) detect the movement of heat-emitting objects. They are equipped with so-called pyrosensors that react to infrared light of a specific wavelength. A vehicle with its engine running radiates heat in the same way as a human body. A PIR detector detects their movement and responds with optical, electrical or acoustic alarm signals.Already knew?Infrared is particularly long-wave light that cannot be seen by the human eye, but can be perceived as heat radiation.A classic motion detector can quickly reach its limits, especially in very dark surroundings or in heavy fog. A PIR detector is a good alternative for this because it detects changes in the thermal image.What do I use a KNX detector with high-frequency sensor technology for?High-frequency sensor technology involves signals in the frequency range between several hundred megahertz and several hundred gigahertz. These signals do not require a medium to propagate in space and penetrate, among other things, wood, glass and lightweight walls.Therefore, this technology is also used in mobile communication and data transmission. A KNX detector with high-frequency sensor technology is used wherever the presence or movement of objects cannot be detected directly for reasons of personal protection or data protection. Classic application examples are public toilets or changing rooms.What is a KNX multisensor?As the name suggests, this is a presence detector with an extended range of functions. In addition to the reliable detection of people and animals, a KNX multi-sensor also determines brightness, room temperature, humidity, air quality, volatile organic compounds and the CO2 content in the air. Such a device can be used, for example, for early fire detection or for monitoring areas in which a certain air quality or a constant climate must be maintained (classrooms, laboratories, greenhouses).Who manufactures KNX presence detectors and KNX motion detectors?Here in the shop you can get detectors from the brands ABB, Berker, Busch-Jaeger, Eaton, EIBMARKT, eQ-3, Esylux, Gira, Hager, Issendorf, Jung, MDT, Merten, Peha, Siemens, Steinel and Theben at top conditions.  Catalogue content:In this eibabo® catalogue Installation bus systems > Movement sensor for bus system you will find items from the following product groups:Item overview:Ceiling adapterCompact guardCorner mountCover panelDetection apertureFully automaticGear sensorHome controlIn-ceiling sensorLightingMoellerfunkMotion detectorMotion sensorNetworkingNickel metallicOutdoor areaOutdoor motion detectorParallel circuitPresence detectorPresence guardRadio systemRadio transmitterRemote controlSplash proofTemperature sensorUltrasonic sensorWall transmitterWireless solutionfrom the following manufacturers:Manufacturer overview catalogue Motion detector:ABBArcliteBerkerBusch JaegerEatonEIBMARKTESYLUXfrogblue AGGiraHagerIssendorffJungMDTMertenPehaSiemensSteinelThebenWAGO
