The Lunatone DALI-2 SI1L is the mains-voltage version of Lunatone's sensor interface: one switching input for 230V signals (LT1, N) with reinforced isolation to the DALI bus. It lets motion sensors, timers or any device with a 230V switched output trigger configurable DALI events — without touching the sensor wiring standard the building already uses.Key features 1 × switching input for mains voltage, cable up to 10m (up to 50m in interference-free routing) Configurable range, target address, DALI on/off commands, hold time and schedule via DALI Cockpit Automatic synchronisation of multiple sensors within a group Reinforced isolation between mains input and DALI Bus powered (4.3mA), fits in a flush box or class II devices DALI-2 certified Technical specifications Supply DALI bus, 4.3mA @ 16.5V Input 1 × 230V AC switching input (LT1, N), max. 10m Mounting back box / class II device integration Dimensions 59 × 33 × 15 mm Ambient temperature -20°C to +60°C · IP20 The retrofit answer when the existing occupancy sensor switches 230V: keep the sensor, add the SI1L, and the signal becomes addressable DALI. Potential-free version: DALI-2 SI. With multi-sensor evaluation logic: DALI-2 SI1L PRO.
