6DR5220-0EM01-0AA0 SIEMENS Exclusive SIPART PS2 Electropneumatic Positioner Original Brand New

The SIEMENS 6DR5220-0EM01-0AA0 is a high-precision SIPART PS2 electropneumatic positioner designed for advanced valve control in demanding industrial environments. Featuring a polycarbonate enclosure and support for 4–20 mA (3/4-wire) input with HART communication, this unit offers exceptional reliability for double-acting pneumatic actuators. Its intrinsic safety (Ex i) certification ensures secure operation in hazardous areas.

This smart positioner provides accurate analog feedback (4–20 mA) and supports optional expansion via digital I/O or analog output modules. It is ideal for process control systems requiring reliable positioning, real-time diagnostics, and enhanced safety features. The device also includes depressurizing functionality for fail-safe conditions (single-acting only), and can be expanded with additional signal monitoring modules.

Overview

SIPART PS2 positioners control valve movement precisely in response to setpoint signals on pneumatic valves. The unit supports intelligent diagnostics both online and offline, enabling proactive maintenance and system optimization. Diagnostics can be extended via optional pressure sensors to detect performance deviations in real time.

Design

The SIPART PS2 is comprised of:

• Durable polycarbonate base and cover, with or without inspection window
• Electronics supporting 4–20 mA, HART, PROFIBUS PA, and FOUNDATION Fieldbus
• Position feedback via potentiometer or non-contacting sensor
• Right-side pneumatic block with connection ports for gauge blocks, boosters, and safety valves

It can be easily mounted to linear or part-turn actuators using the appropriate mounting kit.

Optional Expansion

This model can be optionally upgraded with:

• Analog Output Module (AOM): Analog position feedback 4–20 mA
• Digital I/O Module (DIO): 3 digital outputs, 1 input, limit signaling, fault detection
• Inductive Limit Switches (ILS): NAMUR-compliant independent limit monitoring
• Mechanical Limit Switches (MLS): Independent mechanical limit detection with integrated fault signaling

All modules offer electrical isolation, self-signaling outputs, and are easily retrofitted.

Separate Mounting

For protection in harsh environments, the positioner and position detection unit can be mounted separately. Stroke or angle measurement is performed on the actuator, while the positioner is installed remotely in a protected area and connected via tubing and electrical cables.
