Rheem-Ruud 42-102234-01 SPDT Relay NO/NO 24V

The Rheem-Ruud 42-102234-01 Relay is an electromechanical switching part, which is operated by a 24V control signal to switch the state of internal contacts between normally open and normally closed. It is installed in the electrical compartment of HVAC systems and is connected to control and load circuits with terminal leads, which give a specified switching to compressors, fans, valves, or other system components. This SPDT relay is used to coordinate staging protect sensitive electronics and add to the electrical control of residential and light commercial heating and cooling equipment by isolating control logic on higher-power circuits.
