The EL positioner controls airflow to an actuator and moves it to a position determined by a 4-20mA signal.

It provides fast smooth and precise control from a digital circuit and proportional servo valve.

Calibration is quick and easy via push buttons and LED feedback, making simple field installation. Reversal of rotation sense (clockwise/anticlockwise) can be carried out without the need for special tools or a change of parts.

The unit can be mounted in any orientation on to any quarter turn or linear application by connections via a NAMUR or Kinetrol square interface.

No seperate power supply is needed, just a 4-20mA signal plus air supply.

It's weatherproof, compact and has a robust metal housing with an epoxy stove enamel finish. Vibration and shock resistant to 4G with build in gauge ports / external connections.
