✗ UL Listed
This product has not been certified by an NRTL (UL, ETL, CSA or equivalent). Installation in USA projects may require a Field Evaluation by a recognized laboratory. Consult your local AHJ before specifying.
~ Low Voltage · SELV
This device operates on a Safety Extra Low Voltage circuit — such as the KNX 29V bus or a DALI 16V bus (NEC Class 2). When powered by an NRTL-listed power supply, many AHJs accept non-listed SELV devices. Verify with your local AHJ before specifying.

The Lunatone DALI-2 SI is a tiny sensor interface that brings conventional motion sensors and pushbuttons with a relay output into the DALI-2 world. Wire the sensor's potential-free contact to the SI, and its trigger becomes a configurable DALI event: target address, on/off commands, level, schedule and hold times are all set in DALI Cockpit. Multiple sensors within one group synchronise automatically — clean multi-sensor coverage without controller logic.

Key features

  • 1 × potential-free switching input (T1, COM), cable up to 5m
  • Configurable range, target address, DALI on/off commands, hold time and schedule
  • Automatic synchronisation of multiple sensors in the same group
  • Bus powered (5.1mA), no auxiliary supply
  • Reinforced isolation, fits in a flush box or inside protection class II devices
  • DALI-2 certified; only 40 × 28 × 15 mm

The 2025-generation successor to the classic DALI SI — the cheapest way to make any dry-contact sensor DALI-addressable. For a mains-voltage sensor signal, see the DALI-2 SI1L; for evaluated multi-sensor logic, the DALI-2 SI PRO.
