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.
The SIPART PS2 positioner is characterized by significant advantages compared to conventional devices, such as:
- Only one device version for linear and part-turn actuators
- Simple operation and programming using three keys and a two-line LCD
- Automatic startup function with self-adjustment of zero and span
- Manual operation without additional equipment
- Selectable or freely-programmable characteristics
- Diagnostic functions for valve or actuator (see page 5/4)
- Minimum air consumption
- Selectable setpoint and manipulated variable limiting
- Programmable "tight shut-off function".

The SIPART PS2 positioner is available:
- In a plastic or metal casing for single-action actuators
- In a plastic casing for double-action actuators
- For non-hazardous or hazardous applications in designs
- as intrinsically-safe device (EEx ia/ib) or
- in flameproof casing (EEx d)
and in the versions:
- With 0/4 to 20 mA communication using HART signals (option)
- With PROFIBUS-PA communications interface (EEx ia).
