6DR5120-0NM00-0AA0 SIEMENS Exclusive SIPART PS2 Electropneumatic Positioner Original Brand New

The SIEMENS SIPART PS2 positioner, product code 6DR5120-0NM00-0AA0, is a high-precision electropneumatic solution for controlling valve positions in demanding industrial environments. Engineered for pneumatic linear and part-turn actuators, it supports 4...20 mA control with HART communication, enclosed in a durable polycarbonate housing. Its non-contacting position detection (NCS) ensures wear-free, long-term performance, while its fail-safe function allows depressurizing the actuator in case of power failure (for single-acting configurations).

Optimized for flexibility and control, the SIPART PS2 offers advanced diagnostic capabilities both online and offline. Optional modules, such as analog output and digital I/O, enable further customization. This standard version excludes limit monitoring, option modules, manometer block, and venting gauge block, focusing on streamlined performance without unnecessary add-ons.

Overview

The SIPART PS2 digital positioner accurately adjusts valve positions based on a setpoint signal. Designed to work with pneumatic actuators, it can perform real-time diagnostics during operation and advanced offline analysis between production cycles. For enhanced monitoring, pressure sensors can be optionally integrated.

Design

The device includes:

• Robust polycarbonate housing with or without inspection window
• 4–20 mA terminals (with/without HART), PROFIBUS PA, or FOUNDATION Fieldbus support
• Non-contacting position feedback (NCS) or potentiometer-based
• Pneumatic block with M20x1.5 and 1/4" NPT connections

The SIPART PS2 can be mounted directly or separately from the actuator, offering flexibility in extreme operating conditions. Separate mounting is ideal when direct actuator mounting is limited by radiation, vibration, or other environmental factors. Electrical and pneumatic connections can be extended as required.

Optional expansions include:

• Analog Output Module – Position feedback (4 to 20 mA)
• Digital I/O Module – Limit signaling, alarms, and safety reactions
• Inductive & Mechanical Limit Switches – NAMUR compliant, with fault indication

All modules are retrofittable and electrically isolated for reliable, safe operation in critical systems.
