2 Gang Switching actuator 16A KNX

Product code: 1040 00
The switching actuator receives telegrams from sensors or other controls via the KNX and switches electrical consumers by means of its relay contacts which are independent of one another. Each switching output has a separate bistable switching relay so that the states of the switching contacts are safely maintained even in case of bus voltage failure. With the slide switches on the device front panel, the relays can be switched on and off by hand parallel to the KNX even without bus voltage or in a non-programmed state. This feature permits fast checking of connected consumers for proper functioning.
Price (Excluding VAT)



  • 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.
