Why Engineers Specify This Model
- Self-Calibrating Auto-Tune: The SIPART PS2 performs automatic initialization — it self-learns valve travel, end stops, and friction characteristics without manual adjustment, dramatically reducing commissioning time.
- Minimal Air Consumption: The 5/3-way piezo valve technology consumes extremely low instrument air, reducing utility costs in large installations with hundreds of control valves.
- Integrated Diagnostics: Built-in partial stroke testing (PST) capability and valve signature diagnostics allow predictive maintenance without removing the positioner from service.
- Robust IP66 Enclosure: Suitable for outdoor installation in harsh environments — rain, dust, and washdown conditions do not compromise performance.
- Wide Actuator Compatibility: Compatible with virtually all standard pneumatic linear and rotary actuators via NAMUR mounting, making it a universal retrofit solution.
- Proven Global Track Record: Millions of SIPART PS2 units are installed worldwide across every major process industry — a testament to reliability and long service life.
- Simple Local Operation: Two-button local interface with LCD display allows field technicians to configure, calibrate, and diagnose without a laptop or HART communicator.
Complete System Bill of Materials
The 6DR5120-0NN00-0AA0 is typically installed as part of a complete valve assembly. Common companion parts sourced through Konmask.com include:
- Pneumatic Actuators: Single-acting spring-return actuators (rotary or linear) from Siemens or third-party NAMUR-compatible brands
- I/P Converters: Not required — the SIPART PS2 accepts 4–20 mA directly
- HART Communicator: Siemens SIMATIC PDM or any HART 5/6/7 compatible handheld for advanced parameterization
- Mounting Kits: Siemens NAMUR linear or rotary mounting brackets (order separately per actuator type)
- Air Filter Regulators: Upstream instrument air conditioning units to ensure clean, dry supply air
- Solenoid Valves: For ESD (Emergency Shutdown) integration in safety-instrumented systems
- Position Transmitters: If remote position feedback to DCS is required in addition to positioner function

Application-Specific FAQ
Q: Is the 6DR5120-0NN00-0AA0 suitable for double-acting actuators?
A: No. This variant is designed for single-acting (spring-return) pneumatic actuators only. For double-acting actuators, the correct variant is the 6DR5220 series. Please contact us for the correct part number.
Q: Does this positioner support HART communication?
A: The 0NN00 variant is the standard analog version without integrated fieldbus. HART communication is available on other SIPART PS2 variants. Contact us if you require HART or PROFIBUS PA capability.
Q: Can this positioner be used in a hazardous (Ex) area?
A: This specific variant (0NN) does not carry ATEX or IECEx explosion protection certification. For Zone 1/2 or Division 1/2 hazardous areas, you must specify an Ex-rated variant. Please inquire for the correct Ex version.
Q: What is the minimum supply air pressure required?
A: The SIPART PS2 requires a minimum instrument air supply of 1.4 bar (20 psi). Ensure your air supply is clean, dry, and oil-free per ISA-7.0.01 standards.
Q: How long does commissioning take with the auto-tune function?
A: Automatic initialization typically completes in under 5 minutes for standard valve/actuator assemblies. The positioner self-learns travel, friction, and end stops without manual parameter entry.
Q: What is the lead time for the 6DR5120-0NN00-0AA0?
A: Lead time depends on current stock. Contact us at support@konmask.com for real-time availability. We maintain stock of common SIPART PS2 variants for fast dispatch.
