Description
The Copeland 90-380S1 is a Type 184 fan relay with a 24VAC coil rated at 50/60Hz, featuring both single-pole normally open and single-pole normally closed contact configurations, with a coil resistance of 77 ohms DC and a coil current draw of 125mA, designed for fan control and blower switching applications in residential and light commercial HVAC systems. The 24VAC coil accepts the standard low-voltage control signal from a thermostat or control board to energize the relay, making it directly compatible with conventional HVAC control circuit architectures without the need for an intermediate control transformer or voltage conversion. The dual SPNO and SPNC contact configuration provides switching flexibility for both energize-to-run and energize-to-stop fan control circuit topologies within a single relay body, supporting a wide range of furnace, air handler, and ventilation fan control wiring schemes. The 77-ohm DC coil resistance and 125mA current draw are critical electrical specifications for cross-referencing replacement relays and verifying compatibility with the control board or transformer output supplying the relay coil circuit. As an OEM-quality White-Rodgers Type 184 replacement, the 90-380S1 is a direct-fit service component for HVAC fan control circuits where the original relay has failed or requires substitution during control system service.
