Control & power
- Control type
- Dry-contact input
- Power supply
- 12–24 V AC/DC; board consumption 0.5 A at 12 V or 0.3 A at 24 V with all relays energized
Use one normally open dry contact or open-collector sink per channel. Supply board and load power separately or from a suitably sized common supply; select powered or dry-contact output per channel.
A suitable smart controller can expose supported functions to Matter. The control type alone does not confirm electrical compatibility or actual position feedback.
