6DR5123-0NM01-0AA0 SIEMENS Exclusive SIPART PS2 Electropneumatic Positioner Original Brand New

The 6DR5123-0NM01-0AA0 SIEMENS SIPART PS2 is a smart, electropneumatic positioner designed for precision valve control in demanding industrial applications. Supporting a 4–20 mA input with HART communication, this robust unit features a non-contacting, wear-free position detection (NCS), offering reliable long-term operation with minimal maintenance.

This model is suitable for both linear and part-turn pneumatic actuators, and includes an aluminum enclosure for enhanced durability. It features double-acting functionality and is engineered to perform without integrated pressure sensor options. Standard version includes no explosion protection and excludes the manometer block, venting gauge block, and booster. The analog output module provides analog position feedback (4–20 mA), while auxiliary components like SITRANS I100 isolating power supply and device plugs are orderable separately.

Overview

SIPART PS2 positioners from SIEMENS precisely control valve position based on the received setpoint. They offer intelligent diagnostic functions both online and offline, which can be expanded with pressure sensors. These capabilities allow for comprehensive monitoring and control throughout operational or batch processes.

Design

The SIPART PS2 digital positioner includes the following elements:

• Base plate with or without inspection window depending on model
• Electronics for 4–20 mA input with or without HART, PROFIBUS PA, or FOUNDATION Fieldbus
• Non-contacting sensor (NCS) for position feedback
• Pneumatic block for supply air and actuator pressure, connectable to accessories like boosters or gauge blocks

The SIPART PS2 can be mounted directly to actuators or installed remotely, allowing flexible system integration—especially useful where environmental conditions are not suitable for direct device mounting.

Optional Modules and Functions

SIPART PS2 supports modular expansion:

• Analog Output Module (AOM): 4–20 mA feedback signal
• Digital I/O Module (DIO): 3 digital outputs, 1 input for limit detection or alarms
• Inductive Limit Switches (ILS): NAMUR signal-based, with fault indication
• Mechanical Limit Switches (MLS): Physical switching for two independent limits

All modules are electrically isolated and can be retrofitted with ease.
