Siemens SIPART PS2 User Manual

The positioner is used to move and control pneumatic actuators. The positioner works
electropneumatically, using compressed air as auxiliary power. The positioner is used to
control valves, for example, with:
● Linear actuator
● Part-turn actuator VDI/VDE 3845
Various add-on extensions are available for linear actuators:
● IEC 60534-6-1 (NAMUR)
● Integrated mounting ARCA, except with flameproof versions
● Integrated addition to SAMSON in non-flameproof aluminum enclosure
