Description
The Schneider Electric (Barber Colman) PC-110 is a reliable pneumatic-to-electric (P/E) pressure switch engineered for commercial HVAC building automation and pneumatic control systems. It converts a pneumatic signal into an electrical switching action, bridging pneumatic control circuits with electric loads in two-position control applications.
Switch Operation
The PC-110 features an SPDT (Single-Pole, Double-Throw) switching configuration. On a pressure increase, the switch makes the Normally Open (NO) contact to Common, providing dependable two-position control logic for fans, dampers, valves, and other HVAC equipment.
