IDEC Relays RH1B-ULDC24V SPDT Blade Relay W/Indicator 24 VDC

The IDEC Relays RH1B-ULDC24V Power Relay is a compact plug-in switching component designed to operate electrical loads in systems and control panels. It operates with a 24VDC coil and provides a single-pole, double-throw contact rated up to 10A allowing it to switch blower motors, compressor control circuits, and auxiliary systems. It is installed inside air handling unit or control enclosures where it acts as an interface between low-voltage thermostats and higher-voltage components. The relay ensures electrical isolation and accurate switching within fan control circuits, dampers, and safety interlocks in heating, ventilation and air conditioning systems.
