6DR5223-0EN01-0AA0 SIEMENS Exclusive SIPART PS2 Electropneumatic Positioner Original Brand New

The 6DR5223-0EN01-0AA0 SIEMENS SIPART PS2 smart electropneumatic positioner is a cutting-edge solution designed for precision control of valve positioning on pneumatic linear and part-turn actuators. Engineered for reliable performance, this double-acting unit features a robust aluminum enclosure, HART communication, and compatibility with both 3-wire and 4-wire 4...20 mA signal systems. It is ideally suited for hazardous environments with Ex/nEx protection, specifically intrinsic safety (Ex i) compliance.

This unit operates without a limit monitor or option module, making it a streamlined solution for industrial automation. It supports diagnostics both online and offline, and can be expanded with pressure sensors for advanced feedback. The positioner’s fail-safe functionality ensures depressurization of the actuator in case of auxiliary power failure (for single-acting only), ensuring operational safety.

Overview

SIPART PS2 positioners are intelligent controllers that translate setpoint values into accurate valve positioning. These devices include various diagnostic capabilities that improve reliability and maintenance predictability. The diagnostics can be enhanced with optional modules like pressure sensors, giving even greater insights into valve health.

Design

The SIPART PS2 features:

• Aluminum housing with or without inspection window, depending on variant
• 4...20 mA signal input, with or without HART
• PROFIBUS PA and FOUNDATION Fieldbus (FF) compatibility
• Potentiometer or non-contacting position feedback
• Pneumatic block on right side with support for gauge blocks and boosters

Mounting is flexible using an appropriate kit for either linear or part-turn actuators.

Optional Expansion

This model supports the addition of:

• Analog Output Module (AOM): Position feedback (4–20 mA)
• Digital I/O Module (DIO): Alarm outputs, travel limit signaling, digital inputs for safety triggers
• Inductive Limit Switches (ILS): NAMUR-compliant signal monitoring with integrated fault indicator
• Mechanical Limit Switches (MLS): Physical position limit monitoring with integrated fault detection

All expansion modules are electrically isolated, self-signaling, and easy to retrofit.

Separate Mounting Option

For environments with extreme conditions (e.g., vibration, radiation, magnetic fields), the SIPART PS2 allows remote installation. Only the stroke or angle detection is located on the actuator, while the positioner is mounted safely elsewhere. Electrical and pneumatic connections are maintained via cables and tubes.
