Material number:
  • Integrated power supply
  • Up to 64 operating devices (individual addresses)
  • Up to 16 groups (group addresses)
  • Up to 16 scenes (scene lighting values)

The module is a DALI control device with an integrated power supply. Up to 64 operating devices can be connected.

DALI stands for Digital Addressable Lighting Interface and enables easy and safe control of light fixtures using a standardized digital operating device interface. The DALI bus conforms with EN 62386 series of standards and is now supported by many electronic ballast manufacturers.
