Siemens Process Instrumentation Electropneumatic Valve Positioner SIPART PS2

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. Benefits 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 shut-off" function (ensures maximum positioning pressure on the valve seat) 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 position 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 Can also be operated with purified natural gas, carbon dioxide, nitrogen or noble gases SIL (Safety Integrity Level) 2
