SIPART PS2 is a smart electric valve positioner from Siemens. It has the advantages of simple installation, easy operation, high-quality control, negligible gas consumption during steady-state operation, tight closing function, etc.
The SIPART PS2 is a smart electric valve positioner from Siemens designed for pneumatic linear or angular actuators in a wide range of industries such as chemical, power, and food processing. It offers integrated diagnostics, low gas consumption, and SIL2 safety functions.
This manual covers mechanical installation, wiring diagrams, configuration of analog, HART, PROFIBUS‑PA and FOUNDATION Fieldbus interfaces, diagnostic features, and safety certifications. It also includes ordering data, optional modules, and detailed technical specifications. This manual is written in Chinese.
| Travel range (linear actuator) | 3 … 130 mm |
|---|---|
| Travel range (angular actuator) | 30 … 100° |
| Analog input range | 4 … 20 mA |
| Protection rating | IP66 |
| Supply voltage (3‑wire/4‑wire modules) | 18 … 35 V DC |
The device supports 0‑4 to 20 mA analog signals, optional HART communication, PROFIBUS‑PA, and FOUNDATION Fieldbus (FF) interfaces.
During automatic initialization the micro‑processor determines the actuator zero point, maximum travel, direction, and positioning speed to set the minimum pulse time and dead band.
