Carrier P283-0380 SPNO-SPNC Coil Fan Relay 24V

The Carrier P283-0380 SPNO-SPNC Coil Fan Relay 24V is an electromechanical switch that regulates a fan motor in heating and cooling systems. It gets a low voltage signal and then it switches on a different high voltage circuit that supplies the fan. This relay is used to control the flow of air in HVAC equipment for temperature control and efficient The relay has an electromagnet coil and internal switches. When a low voltage control signal is applied to the coil it produces a magnetic field. The magnetic field physically jumps across and makes and breaks connections within the relay thereby switching on the high voltage supply to the fan motor.
