DALI SI Sensor Interface

Product information "DALI SI Sensor Interface"

DALI SI Sensor Interface with switchin input

Sensor Interface to connect conventional motion sensors or pushbuttons to a DALI system. Configuration options are for example: range, target address, DALI commands for on/off, hold time, … . Multiple sensors within one group synchronise automatically. Two different versions are available: for potential free switching input (DALI SI) and switching input for mains (DALI SI1L). The device is designed to fit behind a light switch in a flush-type box.


  • Module with switching input
  • Easy integration of occupancy and movement sensors, contact switches, photoelectric barrier sensors etc.
  • Same behaviour as DALI CS
  • types with input for potential free contact and input for mains voltage available
  • Multiple trigger sources due to simple external interconnection
  • Configurable schedule (light levels and hold times)
  • Easy configuration with DALI-Cockpit software
  • Multiple DALI SI and DALI CS modules can be installed on the same DALI-line and be used to control the same target range
  • Device is supplied directly by the DALI-line
  • The compact device is suitable for back box installation
