Siemens SIPART PS2 electropneumatic positioner is used to control the final control elements of linear and rotary actuators. With its wide range, and an infinitely adjustable 3- to 130-mm stroke range, SIPART PS2 can be directly integrated to modern actuators without pipe work and without additional overhead. Depending on your application requirements, PS2 can be ordered with 4-20 mA position feedback, three-output alarm module, and limit signaling.

The SIPART PS2 features simple operation, with local manual configuration using three pushbuttons and a user-friendly two-line display. Models with HART communications can also be commissioned and monitored using SIMATIC PDM software. It features extensive diagnostics for both the valve and actuator, including full stroke test, step response and multi-step response tests, and valve performance tests.

  • 0.12" to 5.12" (3 to 130mm) range of stroke for linear actuators, 30° to 100° angle of rotation range for part-turn actuators
  • Mountable in any position (pneumatic connections/exhaust not facing up in wet environments)
  • Automatic commissioning (self-adjustment of zero and span)
  • For operating environments -22° to 176° F (-30° to 80° C)
  • Maximum air consumption in controlled state: <0.036 Nm3/h
  • Can be operated with compressed air, carbon dioxide, nitrogen, noble gases, or cleaned natural gas
  • Required air quality per ISO 8573-1: Class 3 solid particulate size and density, pressure dewpoint, and oil content
  • 0/4-20 mA analog output signal
  • HART, Profibus PA, Foundation Fieldbus communications available
  • NEMA 4X/IP66 reinforced polycarbonate enclosure standard; aluminum and stainless steel enclosures optional
  • SIL 2 Functional Safety compliant to IEC 61508 or IEC 61511 for safe venting
  • FM, CSA, ATEX, IECex approvals
