Gira KNX switching actuators with manual actuation

Gira KNX switching actuator with manual actuation, 4-gang, 16 A

The Gira KNX switching actuators with manual operation and integrated bus coupler are available in the variants 2-gang, 4-gang, and 8-gang 16 A. Depending on the device type, they are used to switch 2, 4, or 8 load groups which can be controlled independently of each other. With the integrated manual switch, changing over the relay (On/Off) is possible in parallel or without KNX operation. 

The DRA actuators are installed on a DIN top-hat rail, and this connection is multi-phase. No other power supply is necessary. Gira recommends ETS 3.0 d for configuring and starting up the device. 


  • Independent switching of 2, 4, or 8 outputs
  • Manual actuation of the relay independent of the bus or switching position indication
  • NO contact or NC contact operation
  • Central switching function
  • Group feedback for reduction of bus load
  • Active or passive cyclical feedback function (object can be read out)
  • Feedback can be delayed until after the bus voltage is restored
  • Logical linking function for each channel
  • Blocking function can be parameterized 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 parameterized per channel
  • Memory function for light scenes
  • Elapsed operating time meter as up/down 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 recovery can be set for each channel following an ETS programming process
