The SIPART PS2 is an intelligent electric valve positioner for pneumatic actuators. It offers automatic initialization, simple three‑button operation, and optional modules such as pressure‑transducers and safety functions. The device can be installed on both linear and angular actuators and supports both 2‑wire and 4‑20 mA power schemes.
Configuration is performed via the built‑in LCD menu or through SIMATIC PDM software. The manual details wiring, module options, communication interfaces (HART, PROFIBUS‑PA, Foundation Fieldbus), and safety certifications (SIL 2, IEC 61508/61511). Environmental ratings, dimensions and protection classes are also provided. This manual is written in Chinese.
| Input signal range | 4–20 mA |
|---|---|
| Typical supply voltage (non‑HART) | 6.36 V |
| Communication protocols | HART, PROFIBUS‑PA, Foundation Fieldbus (FF) |
| Operating temperature range | -30 °C to +80 °C (T4), -30 °C to +65 °C (T5) |
| Dimensions (stroke length) | 3 mm – 130 mm |
| Safety certification | SIL 2, IEC 61508/61511 |
It supports HART, PROFIBUS‑PA and Foundation Fieldbus (FF) communication interfaces.
In a 2‑wire configuration the device draws its power from the 4–20 mA current loop.
The SIPART PS2 meets SIL 2 certification and complies with IEC 61508 and IEC 61511 safety standards.
