A conventional time switch usually switches an electrical relay contact at set times. This is used to realize specific control and automation functions. However, in this eibabo catalog you will find special timers for various automation bus systems, such as radio bus or KNX bus system. KNX time switches, generally, do not dispose of direct switching contacts, but provide the status in digital form as telegrams on the respective bus system or by radio. Depending on the manufacturer, the KNX time switches have diversified but also different characteristics. Most KNX switches feature a day program, week program and year program. Some KNX timers offer a connection option for a DCF or GPS antenna. An automatic summer / winter changeover as well as astro programs. A definition of the geographical location of the building extends the range of options. Switching functions with output of dimming values, switching ON / OFF or UP / DOWN for blinds or shutters, heating control for comfort / standby or night mode, scene release as well as master / slave function are other possible options of KNX time switches. Updating the date and time at KNX displays or other KNX devices in the system by sending the information to the bus are further advantages. Some manufacturers also offer holiday databases, countdown timers and operating hour counters, as well as random programs for simple presence simulations in case of absence to deter potential burglars. A standby in case of power failure is also often standard. What is different is the way to get started. Some manufacturers offer the possibility of direct commissioning of times at the display, programming keys or a separate add-on software or programming solely via the ETS. One should also consider whether another KNX device, which already contains timer programs, is planned in the system, for example KNX weather stations with astro function and GPS / DCF, KNX visualizations (KNX server) KNX displays or complex KNX control and display panels. eibabo provides KNX time switches, KNX time transmitters, wireless timers, KNX year timers, KNX radio switches, KNX week timers, KNX radio blind switches, KNX synchronization timers, digital time switches as well as KNX UP timers of all leading manufacturers, such as ABB, Berker, Busch-Jaeger, Eltako, Hager, Issendorf, Jung,Legrand, MDT, Merten, Peha, Siemens, Theben or Warema.
