Electro-pneumatic positioner for pneumatic quarter-turn actuators which is extraordinary by its easy handling and installation as well as his wide-ranged functions. Automatic initialising, end position indication and analogue position indication is standard. By a switch there is a choice between or current mode or voltage mode and the 3-point-position can be activated.

In combination with the quarter-turn actuator actubar there is no need for tubing or pressure hoses. By direct assembling there is only need for the electric connection and the supply with pneumatic air which will be pressed directly into the actuator chambers onto the actuator top side. Therefore the assembling is easy done and there are no potential leakages. Assembling as per VDI/VDE 3845 is possible also.
