Description
The Trane RLY00902 DPDT Relay is an electrical control unit designed to switch multiple circuits using a low-power control signal. It features a double-pole double-throw configuration that allows it to control two separate circuits with alternating contact positions and it operates with a 24/230V coil for compatibility with different control voltages. In HVAC systems it is commonly used in air handling units, control panels and compressor circuits to manage signal routing between system elements. The relay used as an interface module that enables controlled switching between electrical paths assisting in coordinated system operation.
