Schneider Electric (Erie) AP23A000 Actuator Refrigerant Bypassing a safety limit isThe Schneider Electric Erie AP23A000 Actuator is a 24Vac proportional modulating actuator designed for the Erie PopTop series valve bodies. Built for high performance fluid control in fan coil, baseboard, and air handler systems, this normally open (N. O.) motor utilizes a synchronous motor drive with a robust spring return mechanism. It is compatible with multiple control signals, including 0 10Vdc, 0 5Vdc, 5 10Vdc, and 4 20mA, allowing for precise
