The Tridonic DALI RM CDM 30 10A 1CH is a DALI-2 compliant 1-channel relay designed for switching loads. It is suitable for mounting on a 35 mm DIN rail and is optimized for electronic loads with high inrush currents, such as LED drivers.
Product Description

- DALI-2 relay compatible with DALI and DALI-2 systems.
- 1-channel actuator with DALI-2 input.
- Potential-free relay contact.
- Optimized for high inrush currents up to 490 A / 1.5 ms.
Installation
Installation must be performed by qualified personnel only. Ensure the power supply is disconnected before starting work.

- Mount the device on a 35 mm DIN rail.
- Use solid or stranded wire with wire end ferrules, cross-section 1 to 4 mm².
- Strip wire insulation by 6–7 mm.
- To remove from the DIN rail, use a flat-head screwdriver to release the locking lever.
Wiring
Connect the mains supply (L, N) and the load according to the provided wiring diagrams. The device supports switching of loads that do not have a DALI input.
