The PROMATION PA Series SPRING RETURN electric actuator is designed for load requirements up to 445 in lbs. The actuator comes standard with two auxiliary switches (Form C), an internal low power heater, a NEMA 4X environmental rating, and in 120/230 VAC or 24 VAC/DC supply voltages. The PD Series mechanical connections utilize an ISO5211 mounting system, size F07 with an 8 point 17 mm female drive. The PA Series is offered in two different control modes….On/Off (2 position control) or Proportional (modulating control). Application requirements will dictate whether to utilize a CW (clockwise spring return) or CCW (counter-clockwise spring return) model.  Spring return direction is NOT changeable and actuator must be configured for spring direction at time of order.
