Functionality

The PositionMaster EDP300 is an electronically configurable positioner with communication capabilities designed for mounting
on pneumatic linear or part-turn actuators.
Fully automatic determination of the control parameters and adaptation to the positioner allow for considerable time savings as
well as optimum control behavior.
