An electric actuator designed for a wide range of torque requirements. The actuator comes standard with two auxiliary switches (shared common, rated
at 3A 250V Max), an internal low power heater, a NEMA 4X environmental rating, and in 12VAC/DC, 24VAC/DC, 120VAC or 230VAC supply voltages.  The actuator’s mechanical connections are ISO5211 compliant, utilizing an F03/F05 bolt pattern and an 8 point 14mm female drive. IMI PBM’s electric actuator is available
as on/off or two position models that can also be used in bump/jog applications. It can also be ordered with an internal proportional control card that accepts a wide range of control signals and generates multiple feedback signals.
