Copeland Comfort Control (White Rodgers) 90-342S1 Magnetic Relay is an electrical switching component that controls the flow of power between the low voltage control circuit and higher-voltage equipment within HVAC systems. It responds to signal from thermostat or control board allowing connected motors, compressors, blowers or fans to operate as required during cooling and heating cycles. This is commonly installed inside control panels, air handlers, furnaces, rooftop units and other equipment. It operates as an interface between the control system and electrically powered components to ensure normal equipment operation.
