The DALI-2 RELAY DIN RAIL 4CH-12A is a 4-channel relay module for simplifying load management by integrating non-DALI loads into DALI systems. The relay unit is for DIN rail mounting. It supports a continuous current load of up to 12 A per channel, making it suitable for a wide range of applications. It also features zero-crossing detection for smooth and safe switching and allows independent control of four relays.
