The positioner is used to adjust and regulate pneumatic drives. The positioner works
electropneumatically, using compressed air as auxiliary power. The positioner can e.g.
regulate valves with:
● linear actuator
● Part-turn actuator VDI/VDE 3845
For linear actuators, there are various add-on extensions available:
● NAMUR or IEC 534
● Integrated addition to ARCA
● Integrated addition to SAMSON in non–explosion-proof housing
You can mount the positioner on the usual drives and operate it with the usual drives.
