New Original Siemens 6DR5125 SIPART PS2 Digital Valve Positioner for Industrial Process Control

The Siemens SIPART PS2 6DR5125-0EG01-0AA2 is a compact, intelligent electropneumatic positioner from the SIPART PS2 series. It delivers precise control of pneumatic linear and part-turn actuators using a 2-wire 4-20 mA signal with HART communication. Housed in a rugged aluminum enclosure, it supports both non-hazardous and hazardous-area applications with built-in diagnostics and automatic commissioning.

• Fully automatic initialization for linear and part-turn actuators
• Extremely low air consumption in steady state (< 0.036 Nm³/h)
• Comprehensive valve and actuator diagnostics (valve signature, partial stroke test, full stroke test)
• Non-contacting position sensor option (NCS) for vibration-heavy environments
• IP66 / NEMA 4X protection with C5-M corrosion resistance
• SIL 2 functional safety capability

Widely used in chemical, petrochemical, oil & gas, power generation, pharmaceutical, food & beverage, and water/wastewater plants for precise valve positioning on control valves and dampers.

Q: Does this model support PROFIBUS or FOUNDATION Fieldbus?
A: No — this variant uses 4-20 mA/HART only.

Q: Can it be used with natural gas as supply medium?
A: Yes, when configured per the operating instructions.

Q: Is explosion protection included?
A: The base model supports Ex i / Ex d options via ordering code extensions.
