Description
The IDEC Relays RH2B-ULDC24V General Purpose Relay Plug-In with DPDT contact arrangement, designed for switching control circuits using a 24V DC coil and supporting up to 10A contact rating. It is used for signal switching and electrical isolation between control and load circuits in compact electrical panels. Within HVAC systems, it is commonly installed in control panels and air handling units to coordinate the operation of components such as fans, compressors, and dampers based on incoming control signals. The relay works through an electromagnetic coil that shifts internal contacts to alternate circuit paths.
