4 Gang Switching actuator 16A C-load KNX

Product code: 1045 00
For switching four independently controllable loads. The switching contacts are especially designed for loads with a capacitive character with brief, high switch-on currents. Each channel has integrated current detection and a manual switch for switching the relay (On/Off) with or without KNX operation. No additional power supply required.

  • Independent switching of the 2 outputs.

  • Manual actuation of the relay independent of the bus/switching position display.
  • NO contact or NC contact operation.
  • Central switching function.
  • Group feedback for reduction of bus load.
  • Active or passive (object can be read out) cyclical feedback function.
  • Feedback can be delayed until after the return of bus voltage.
  • Logical linking function for each channel.
  • Block function can be parameterised for each channel. As an alternative, forced setting function for each output.
  • Time functions (switch-on, switch-off delay, staircase light function - also with advance warning function).
  • Inclusion in light scenes possible, maximum of 8 internal scenes can be parameterised per channel.
  • Memory function for light scenes.
  • Elapsed-hours meter as forward/backward counter with limit function (limit can be changed via bus) can be activated for each output.
  • Input monitoring for cyclical updating with safety setting.
  • Reactions in case of bus voltage failure and restoration can be set for each channel following an ETS programming process.
  • Current detection: Measurement of load current for each channel.
  • Threshold values for load monitoring (e.g. signalling of load failure).
