6DR5123-0NN01-0AA0 SIEMENS Exclusive SIPART PS2 Electropneumatic Positioner Original Brand New

The 6DR5123-0NN01-0AA0 SIEMENS SIPART PS2 is a smart, electropneumatic positioner designed for accurate and reliable valve control in complex industrial applications. Operating on a 4...20 mA signal with HART protocol, this unit supports both Ex and nEx environments and is optimized for double-acting actuators. Its non-contacting sensor (NCS) ensures wear-free position detection, extending operational life and reducing maintenance requirements.

This SIPART PS2 version features an aluminum enclosure and is suitable for linear and part-turn actuators. It comes standard without explosion protection, includes analog feedback output (AOM 4...20 mA), and supports flexible integration into automation systems. While the pressure sensor options P01/P02 are not included, this unit is ideal for standard operations needing high-precision feedback and control. The device also allows optional connection to M12 device plugs and isolating power supplies.

Overview

SIPART PS2 positioners are engineered to convert setpoint signals into precise valve positioning. They offer advanced diagnostics—both online during operations and offline between batches—to verify valve behavior and condition. Optional expansion with pressure sensors further enhances the diagnostic capabilities.

Design

The digital SIPART PS2 includes:

• Base plate and enclosure with/without inspection window
• Electronics with support for: 4–20 mA, HART, PROFIBUS PA, and FOUNDATION Fieldbus (FF)
• Non-contacting position feedback (NCS) or potentiometer options
• Pneumatic block with right-side air supply and actuator pressure ports
• Optional connection for gauge blocks, venting, booster, or solenoid valves

Mounting options allow installation on either linear or part-turn actuators with standard kits. The modular design also permits remote mounting—placing the positioner away from harsh valve environments and connecting it electrically and pneumatically.

Optional Modules

SIPART PS2 supports:

• Analog Output Module (AOM): Provides 4...20 mA analog feedback
• Digital I/O Module (DIO): 3 digital outputs + 1 digital input with alarm features
• Inductive Limit Switches (ILS): Monitors 2 limits with integrated fault indicators
• Mechanical Limit Switches (MLS): Offers mechanical limit feedback with fault detection

All modules are electrically isolated and easy to retrofit for existing systems.
