SIEMENS SIPART PS2 with remote control electronics 

100% New & Original with very competitive price and One year Warranty  




In addition to the properties of the compact design, the SIPART PS2 provides the option for separate, remote control electronics. 

This allows the use in environmental conditions with high energy radiation. The control electronics is then fitted into a rack unit (19"), 

whereas the position detection system and the pneumatic unit remain on the valve.

The SIPART PS2 electropneumatic positioner is used to control the final control element of pneumatic linear or part-turn actuators. 

The electropneumatic positioner moves the actuator to a valve position corresponding to the setpoint. Additional function inputs can be used to 

block the valve or to set a safety position. A binary input is present as standard in the basic device for this purpose.




SIPART PS2 positioners offer decisive advantages:

  • Simple installation and automatic commissioning (self-adjustment of zero and span)

  • Simple operation with:

    • Local operation (manual operation) and configuration of the device using three buttons and a user-friendly two-line display

    • Parameterization via SIMATIC PDM

  • Very high-quality control thanks to an online adaptation procedure

  • Negligible air consumption in stationary operation

  • "Tight closing" function (ensures maximum positioning pressure on the valve seat)

  • "Fail in place" function: Current position is retained on failure of auxiliary electrical power and/or pneumatic failure (does not apply in conjunction with SIL).
    Example: For an actuator with a volume of 8 liters, the typical position stability of a SIPART PS2 with "Fail in place" is 0.3% per hour.

  • Numerous functions can be activated by simple configuring (e.g. characteristic curves and limits)

  • Extensive diagnostic functions for valve and actuator

  • Only one device version for linear and part-turn actuators

  • Few moving parts, hence insensitive to vibrations

  • External non-contacting sensor as option for extreme ambient conditions

  • "Intelligent solenoid valve": Partial Stroke Test and solenoid valve function in a single device

  • Partial Stroke Test e.g. for safety valves

  • Full Stroke Test, Multi Step Response Test, Valve Performance Test for performance and maintenance evaluation of the valve

  • Can also be operated with purified natural gas, carbon dioxide, nitrogen or noble gases

  • SIL (Safety Integrity Level) 2




The SIPART PS2 positioner is used, for example, in the following industries:

  • Chemical/petrochemical

  • Power stations

  • Paper and glass

  • Water, waste water

  • Food and pharmaceuticals

  • Offshore plants


The SIPART PS2 positioner can be used with all pneumatic actuators and is available for delivery:

  • In various enclosure designs and various materials (polycarbonate, aluminum, and stainless steel)

  • For non-hazardous applications

  • For hazardous applications in the versions

    • Intrinsic safety type of protection

    • Flameproof enclosure type of protection

    • Non-sparking type of protection

    • Type of protection dust explosion protection by enclosure

and in the versions:

  • With 0/4 ... 20 mA control with/without communication through HART signal

  • With PROFIBUS PA communication interface

  • With FOUNDATION Fieldbus (FF) communication interface




The SIPART PS2 positioner is a digital field device with a highly-integrated microcontroller.

The positioner consists of the following components:

  • Enclosure and cover

  • PCB with corresponding electronics with or without communication through HART 7
    or with electronics for communication according to

    • PROFIBUS PA specification, IEC 61158-2; bus-supplied device, or

    • FOUNDATION Fieldbus (FF) specification, IEC 61158-2, bus-supplied device

  • Position detection system

  • Terminal housing with screw terminals

  • Valve manifold with piezoelectric valve precontrol

The valve manifold is located in the enclosure, the pneumatic connections for the inlet air and the positioning pressure on the right-hand side of the enclosure. 

A pressure gauge block and/or a safety solenoid valve can be connected there as options. The SIPART PS2 positioner is fitted to the

 linear or part-turn actuator using an appropriate mounting kit. The circuit board container in the casing provides slots for separately ordered boards with the following functions:




Comprehensive monitoring functions

The SIPART PS2 has various monitoring functions with which changes on the actuator and valve can be detected and signaled if applicable 

when a selectable limit has been exceeded. This information may be important for diagnosis of the actuator or valve. 

The measuring data to be determined and monitored, some of whose limits can be adjusted, include:

  • Travel integral

  • Number of changes in direction

  • Alarm counter

  • Self-adjusting deadband

  • Valve end limit position (e.g. for detection of valve seat wear or deposits)

  • Operating hours (also according to temperature and travel ranges) as well as min./max. temperature

  • Operating cycles of piezoelectric valves

  • Valve positioning time

  • Actuator leakages
