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

Benefits

• Negligible air consumption in stationary operation.
• “Fail in place” function: Current position is retained on electrical power failure .
• Only one device version for linear and part-turn actuators
• External non contacting sensor as option for extreme ambient conditions
• “Intelligent solenoid valve”: Partial Stroke Test and solenoid valve function in one device
• Can also be operated with purified natural gas, carbon dioxide, nitrogen or noble gases
• SIL (Safety Integrity Level) 2
• Numerous functions can be activated by simple configuring.
