Trane RLY1039 DPST Delay Relay 10-120 Sec 24V 30A

The Trane RLY1039 is a 24V /DPST/ delay relay intended for HVAC systems only. It brings a time delay between the control signal activation and the switching of its contacts. It delays the on or off command of a device by a certain number of seconds, which can be between 10 and 120 seconds. This relay is typically applied for HVAC equipment such as fans to provide enhanced comfort and optimization. The time taken before the fan ceases to operate after the compressor has stopped is beneficial in making certain that the cool air from the coil gets into circulation.
