6DR5020-0NG00-0AA0 SIEMENS Exclusive SIPART PS2 Electropneumatic Positioner Original Brand New

The SIEMENS 6DR5020-0NG00-0AA0 SIPART PS2 is an advanced, smart electropneumatic positioner designed for pneumatic linear and part-turn actuators. Built with a durable polycarbonate enclosure, it features a non-contacting (wear-free) position detection system (NCS) and supports 4–20 mA input with Ex/nEx compatibility. This variant is double-acting and does not include explosion protection, limit monitor, or option modules, making it an efficient and reliable solution for general industrial use.

This model offers reliable valve positioning control and supports advanced diagnostic capabilities both online and offline. It operates without a manometer block, venting gauge block, or booster, simplifying maintenance and reducing component complexity. With support for Fail-Safe functionality (depressurizing actuator in the event of power failure), it ensures process safety in demanding environments.

Overview

SIPART PS2 positioners are ideal for precise valve control based on setpoint signals in industrial processes. The device allows verification of valve performance using real-time and batch-time diagnostic tools. Diagnostic functions can be further enhanced with optional pressure sensors to provide deeper insights into system performance.

Design

The SIPART PS2 digital positioner includes:

• Base plate with inspection window or solid lid (depending on variant)
• Electronics supporting 4–20 mA, HART, PROFIBUS PA, or FOUNDATION Fieldbus
• Non-contacting sensor (NCS) or potentiometer for position feedback
• Pneumatic block with right-side connections for supply air and actuation

Optional expansion includes:

• Analog Output Module for 4–20 mA feedback
• Digital I/O Module with alarms and travel limit signaling
• Inductive Limit Switches and Mechanical Limit Switches for position monitoring

All modules are electrically isolated, self-monitoring, and easily retrofitted.

Separate mounting of the positioner is supported, allowing remote installation in protected environments. This is beneficial in high-vibration, magnetic, or harsh operating conditions where direct mounting is not suitable.
