Gira KNX/EIB universal dimming actuator 50–210 W/VA

KNX universal dimming actuator 50–210 W/VA

The Gira KNX universal dimming actuator 50–210 W/VA is used to switch and dim lamps. It is equipped with two binary inputs for installation in the switch box (electronics box from Kaiser recommended). Potential-free contacts can be connected to the two binary inputs, and both inputs can perform different functions or be blocked independently of each other during this process. As a factory setting, the inputs are assigned to the dimming actuator, enabling operation without programming.

Connection to the 230 V power supply is via a flexible cable approx. 20 cm in length. The binary inputs and the KNX are connected via a 6-wire connection cable approx. 30 cm in length. The connection cable for the binary inputs can be extended to a maximum of 5 metres.


  • Switch-on and dimming behaviour can be set with parameters
  • Feedback of switching condition and brightness level
  • 'Soft ON', 'Soft OFF' and time dimmer are configurable
  • Dimming or brightening of brightness levels
  • Time-delayed switch-off possible if a switch-off brightness level is not reached
  • Short-circuit and load failure messages possible
  • Light scene operation possible
  • Blocking operation can be activated via an object with a parameterizable brightness level at the start and end of a blocking phase 
  • Behaviour of the dimming actuator following bus voltage recovery can be specified


  • Free assignment of the functions switching, dimming, blind and encoder to both inputs
  • Blocking object for blocking individual inputs
  • Behaviour when the bus voltage is restored can be parameterized separately for each input
  • Telegram rate limitation
  • Switching function: two independent switching objects are available for each existing input and can be enabled individually, command for leading and trailing edge can be set independently (ON, OFF, CHANGE, no reaction)
  • Dimming function: single and double-surface operation, time between dimming and switching and dimming increment can be set, telegram repetition and stop-telegram transmission possible
  • Blind function: command can be set with rising edge (no function, UP, DOWN, CHANGE), operating concept can be parameterized (Step - Move - Step or Move - Step), time between short and long-term operation can be set, slat adjustment time can be set
  • Encoder and light scene auxiliary unit function: edge (button as NO contact, button as NC contact, switch) and value with edge can be parameterized, value adjustment with button by pressing and holding button for encoders possible, light scene auxiliary unit with memory function and saving of the scene without previously calling up is possible
