KNX control unit 1-10 V, 4-gang with manual mode

Product code: 2224 00
Designed with flexibility in mind the Gira 1-10v control unit has 4 control outputs and 4 relay outputs which can can be configured in 5 different formats. Unused relays can be controlled independently or control outputs can be grouped to a single relay for RGB control. There are a wide range of additional features including logo,scenes, sequences, burn in timers and time functions.

  • The controller unit switches and dims electrical devices that have a 1-10 V interface.
  • Five device configurations can be selected. This leads to the assignment of four individually-controllable dimming channels to the switching outputs (e.g. four dimming channels are assigned to one switching relay to control a RGBW light).
  • Relay outputs that are not associated with a dimming channel can be used as freely-acting switching actuator channel.
  • Reactions in case of bus voltage failure and restoration can be set following an ETS programming process. 
  • Manual actution of outputs independent of the bus with mechanical switching position indication. 
  • Delay for actively transmitted feedback messages following bus voltage recovery. 
  • Logical linking function configurable per channel. 
  • Up to three central switching functions for the joint control of all dimming and switching channels. 
  • Switch-on times of the relay outputs can be recorded and evaluated by the elapsed operating time meter. 
  • Group feedback of all switching conditions possible. 

Dimming channels 

  • Four individually-controllable dimming channels.
  • Feedback on switching condition and brightness value.
  • Dimmable brightness range can be set. 
  • Dimming behaviour and dimming characteristics can be parameterised. 
  • Soft switch-on and soft switch-off function.
  • Block function or forced setting function can be parameterised. 
  • Time functions (switch-on delay, switch-off delay, staircase light function). With the staircase light function, the reaction at the end of the switch-on time can be configured. 
  • Inclusion of a dimming channel in up to ten scenes is possible. 
  • The burning-in function allows for the start-up of new fluorescent lamps prescribed by lighting manufacturers. 

Switching actuator operation (optional)

  • Independent switching of switch outputs A2 to A4.
  • NO contact or NC contact operation. 
  • Feedback from the switching condition. 
  • Block function or forced setting function can be parameterised. 
  • Time functions (switch-on, switch-off delay, staircase light function - also with advance warning function). 
  • Can be integrated in the light scenes. Up to ten internal scenes per switching output are programmable.
  • Cyclical monitoring of incoming switching telegram is configurable.
