Single & double-acting positioners RE01 require an input signal of 4/20 mA for proportional control actuator. The Positioner compares the output signal from a controller with the position feedback, and varies a pneumatic output signal to the actuator accordingly. The actuator position is therefore guaranteed for any controller output signal and the effects of varying differential pressure.
