Application range

  • Use in building system technology, e.g. for decentralised control of lighting, heating, air-conditioning, ventilation, energy management, blinds, time recording, locking systems etc.
  • The cable can be laid on, in or under plaster; in pipes, cable ducts; in dry, damp or wet environments.
  • EIB (European Installation Bus) installation mainly consists of sensors/command transmitters (e.g. light barriers, switches, thermostats, infrared, wind meters, timers) and actuators (e.g. motors, heaters, ventilators, lights, blinds).
  • KNX technology was formed from the merging of three established European bus standards: EIP, EHS (household appliances and consumer electronics) and Batibus (heating/ventilation/air conditioning).
