Reznor 259521 Time Delay Relay Sequencer Kit

The Reznor 259521 Time Delay Relay Sequencer Kit is an essential component of the HVAC systems. Designed to work by the management of time intervals of electrical circuit. It has a thermal or an electronic timer that controls the time taken before relays open or close so that parts such as blower motors, heaters, and compressors are turned on and off in a sequence. In its operation, the sequencer triggers connected components after a specific time has elapsed to avoid a high inrush current that would cause a load on the power system.
