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.
SIPART PS2 in stainless steel enclosure with pressure gauge
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:
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:
Paper and glass
Water, waste water
Food and pharmaceuticals
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:
Number of changes in direction
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
