EP100 Analog Positioner
The analog Positioner EP100 with analog input 4 to
20 mA is designed to operate pneumatic valve
actuators. It offers an easy adjustment by means of
switches and potentiometers. The modular
structure of the EP positioner series enables the
feasibility to re-fitt optional equipment (limit switch).
