GIRA KNX control unit 1 – 10 V, 4-gang with manual actuation

Low stock.

Available for Next Day Delivery.

Available for Next Day Collection.


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 elapsedoperating 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.
