Trane RLY3081 Time Delay Relay 2Sec ON/45 Sec Off

The Trane RLY3081 Time Delay relay is used in HVAC systems that require delayed start and stop on equipment. This relay features the ON delay of 2 seconds, and the OFF delay of 45 seconds to secure correct functioning and to avoid early cycling or destruction. It operates based on incorporating a time constant between the application of an input signal and the supply of energy to the output circuit. This is important to allow stabilization or purging operations to be executed before other interconnected equipment is fully activated. The RLY3081 is applied in different HVAC system applications such as chillers, boilers, and fan control.
