Description
The York S1-02436138000 Control Relay is an electromechanical switching component used to manage low-voltage control circuits. It operates on a 24V, 60Hz coil signal and operates as a double-pole single-throw systems with a normally open configuration allowing it to switch two separate electrical paths simultaneously in HVAC systems equipment. It is installed within air handlers or packaged units where it works as an intermediary between thermostats, control boards and high-voltage components. By receiving a low-voltage signal, it enables or interrupts power flow to downstream systems such as compressors, fan motors or heating elements, supporting coordinated system operation and control logic within the overall system.
