Trane RLY02807 Time Delay Relay W/PC Board

The Trane RLY02807 Time Delay Relay with a printed circuit board is intended to provide a desired time delay in the control of HVAC systems. This relay works based on on delay timer which is the type of delay timer that delays the triggering of a circuit for a fixed time after the receipt of the signal. This time delay is important in many HVAC applications including: avoiding short cycling of the compressor, controlling the staging of multiple components, and managing the fan operation for the best system performance.
