Schneider Electric (Barber Colman) PAM-1 SPDT Relay Module 24 VAC/DC 120 VAC

The Schneider Electric (Barber Colman) PAM-1 Relay Module is the electromechanical switching part it is used to operate electrical circuit in HVAC systems. The module has a single-pole, two-throw design, which enables the module to switch current flow between two outputs in response to an input signal. It has control voltages of 24 VAC/DC or 120 VAC allowing it to integrate with thermostats, sensors and control panels. The relay mounted on control panels offers signal isolation, circuit switching and protection, which ensures accurate operation of compressors, fans, or auxiliary components and stability and coordination of systems.
