  • 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.
