Description
The Trane RLY3566 Time Delay Relay is an electronic control component designed to introduce a controlled time delay in electrical switching operations. Operating on a 120V power supply with an adjustable delay range of 0.1 to 10 minutes, it regulates contact activation and deactivation through an internal timing circuit. It is used in HVAC systems such as air handlers, compressors, and control panels to sequence equipment operation and manage start-up timing. Installed within the control circuit, it supports coordinated electrical switching, maintains operational timing accuracy, and contributes to stable system sequencing.
