Description
The IDEC Relays RH1B-UDC12V SPDT Relay is an electromechanical switching component rated at 12 VDC coil voltage and 10A contact capacity. It is used to control electrical circuits by opening and closing contacts in response to a low-voltage control signal in HVAC systems. It is integrated into control panels to switch compressors, fans, dampers, and safety circuits. The relay controls as an interface between control logic and higher-power loads, enabling accurate signal isolation and circuit management. It is installed in industrial control cabinets and building automation systems where coordinated operation of equipment is required for efficiency.
