8-channel LED Dimming Actuator – RE KNT 008

8 Channel Dimming Actuator


  • Dimming Actuator with 8 output channels, designed for the control of resistive, inductive, capacitive and LED loads.
  • Phase-cut dimming technology, both leading and trailing edge, configurable by ETS parameter:
    • 230V dimmable LED Lamps.
    • 12V dimmable LED Lamps with Electronic transformer.
    • Incandescent and 230V Halogens.
    • Halogens with Electronic transformer.
  • The 8 channels can be configured as:
    • Independent channels: It allows to control the different output channels independently.
    • Sequencer: The 8 channels are controlled together at the same time with predefined sequences.
  • It incorporates a keyboard on its front that allows manual control of each of the channels.
  • Protected against overloads and short circuits. It incorporates heating protection with resettable operation.
  • It has an LED indicating error due to over-temperature or overload.
  • Modular housing (8 modules width), for DIN-rail mounting.
  • Programming and commissioning via ETS5 or later versions.
  • Built-in KNX Bus Coupler Unit (BCU).
