6DR5123-0NG01-0AA0 SIEMENS Exclusive SIPART PS2 Electropneumatic Positioner Original Brand New

The 6DR5123-0NG01-0AA0 SIEMENS SIPART PS2 is a high-precision electropneumatic positioner designed for both linear and part-turn pneumatic actuators. As part of the renowned SIPART PS2 series, this model features non-contacting, wear-free position detection (NCS), ensuring longevity and maintenance-free operation in demanding industrial applications. It operates with a 4...20 mA input signal, supports HART protocol, and is double-acting with an aluminum enclosure, providing robust durability in harsh environments.

With diagnostic capabilities during both online and offline operation, this device enables predictive maintenance and fault analysis. The SIPART PS2 also allows expansion with modules like Analog Output Module (AOM) for 4...20 mA feedback, and Digital I/O Modules for alarms, limit monitoring, and fault reporting. It is fail-safe ready, offering depressurization of the actuator in case of auxiliary power failure (for single-acting actuators only). The unit does not include manometer or booster modules by default.

Overview

SIEMENS SIPART PS2 positioners are used to control pneumatic valve positioning based on the control signal. They offer intelligent diagnostics, both online during process operation and offline between batch processes. These functions can be extended with optional pressure sensor modules.

Design

The SIPART PS2 comprises several core components:

• Base plate with or without inspection window
• Electronics supporting 4–20 mA, HART, PROFIBUS PA, and FOUNDATION Fieldbus
• Non-contacting sensor (NCS) or potentiometer-based position feedback
• Right-side pneumatic connections for air supply and actuation

Optional modules and functions include:

• Analog Output Module (AOM) for 4–20 mA feedback
• Digital I/O Module for limit signaling and alarms
• Inductive and Mechanical Limit Switches (ILS/MLS) for threshold monitoring
• Electrical isolation for all signals and integrated fault indicators

The positioner can also be mounted separately from the valve actuator, enabling protected installations in harsh environments. This flexibility makes the SIPART PS2 ideal for applications where space, temperature, vibration, or other conditions may affect direct mounting.
