SmartBus SB-2R-UNS-Bus 2-ChannelRelay

SmartBus SB-2R-UN — compact S-Bus relay module with two independently switched channels rated at 2A each, for low-load automation control.

The SB-2R-UN integrates into SmartBus S-Bus networks to provide switched control of two low-current loads — typically LED drivers, fan coil units, or indicator circuits. With a 2A per channel rating it is suited to lower-power loads where full switching relay capacity is not required. Addressable from any SmartBus controller or automation panel on the same bus.

Suitable for LED drivers, fan coils, and indicator circuits
