Description
The Emerson Climate-White Rodgers 90-291Q Fan Relay controls electrical switching for fan motor circuits by opening and closing connections based on signals received from the system control assembly. Featuring a 1-pole single normally open SPNO configuration, this relay operates at 120 VAC and supports both 50 and 60 Hz electrical frequencies for appropriate equipment requirements. Integrated into airflow and temperature management sections of HVAC systems, it directs circuit activation for fan operations, allowing an organized electrical response during heating or cooling cycles.
