Rheem PD425047 24V Single Pole Single Throw Normally Open Sequencing Relay

This Rheem Sequencing Relay is a specialized electrical component designed to control the sequence of operations in a heating, ventilation, and air conditioning (HVAC) system. It operates on a 24-volt (24V) power supply and features a Single Pole Single Throw Normally Open (SPST-N/O) configuration. This means that the relay has one switch (single pole) that can be connected in one way (single throw), and it remains open until energized. The sequencing aspect of this relay allows for the orderly activation of multiple functions within an HVAC system, ensuring smooth operation and preventing potential damage from simultaneous activation.
