Flexible and Expandable: Tailored to Fit Your Valve Applications

The SIPART PS2 digital positioner is meticulously designed to deliver exceptional functionality and adaptability. Its construction includes a base plate with a lid, available with or without an inspection window, depending on the variant. It houses advanced electronics with screw-type terminals, supporting 4 to 20 mA, 4 to 20 mA with HART, PROFIBUS PA, and FOUNDATION Fieldbus (FF) communication protocols. Position feedback is achieved via a potentiometer or a non-contacting sensor (NCS). A pneumatic block is incorporated, with connections for supply air and actuating pressure conveniently located on the right side of the enclosure. Optional components such as a gauge block, venting gauge block, booster, VDI3847 interface, or safety solenoid valve can be integrated to enhance its versatility.

The SIPART PS2 can be fitted to linear or part-turn actuators using a suitable mounting kit and allows for further customization through optional modules, including Analog Output Modules (AOM) for 4 to 20 mA feedback, Digital I/O Modules (DIO) for alarm and safety signaling, and limit switches for precise monitoring. Its design also supports separate mounting of the positioner and position detection system, enabling installation in protected areas for harsh operating environments. This modularity and expandability ensure the SIPART PS2 meets a wide range of application requirements with ease and reliability.
