Description
The IDEC Relays RH1B-UDC24V Plug-In Relay is an electrical switching component for controlling circuits within industrial equipment control panels and HVAC systems. This single-pole double-throw relay operates on 24 VDC control voltage which indicates the voltage required to energize the relay coil during operation. It configuration allows the relay to be installed or replaced within compatible relay sockets without direct wiring to the terminals. It is commonly used for signal switching, control circuit operation, and automated electrical response in equipment requiring controlled switching between connected circuits.
