Rheem-Ruud PD425078 DPST Sequencing Relay Normally Open 24V

The Rheem-Ruud PD425078 Sequencing Relay is a component that is integrated in HVAC systems so as to manage and order the circuitry. This relay is of DPST configuration with the coil voltage of 24V. As the relay is energised the Normally Open (NO) contacts come together to make a complete connection. Although it is not wide in scope it is rather strong in terms of activity. The working of the PD425078 relay is done through the control of several electrical loads in a sequential manner; this ensures that all the components of the HVAC systems such as fans and heating elements turn on as they are supposed to. This is the sequencing needed to retain system efficiency and to prevent electrical overloads or harm to the system.
