Description
The Trane RLY01388 DPDT Control Relay Coil 50/60Hz is an electromechanical switching component used in maintenance systems to manage electrical circuits through a low-voltage control signal. It contains a 24-volt coil that energizes internal double-pole, double-throw contacts rated for switching line-voltage loads up to 120/600 volts. In HVAC systems, equipment includes are air handlers, heat pumps, and packaged units, it is installed within the control panel to route signals between thermostats, compressors, fans, and safety circuits. Within the system, it operates as an interface between control logic and power distribution, enabling coordinated operation of heating and cooling stages.
