6DR5223-0EN00-0AA0 SIEMENS Exclusive SIPART PS2 Smart Electropneumatic Positioner Original Brand New

The 6DR5223-0EN00-0AA0 SIEMENS SIPART PS2 Smart electropneumatic positioner is engineered for precise and intelligent control of pneumatic actuators. This high-quality, original brand-new unit is designed for both linear and part-turn applications, supporting 4–20 mA (3/4-wire) control signals with integrated HART communication. It features a rugged aluminum housing and double-acting functionality for reliable performance in hazardous areas with Ex i (intrinsic safety) protection.

This positioner supports fail-safe operation—automatically depressurizing the actuator in the event of auxiliary power failure (for single-acting setups). Its modular design allows integration of various accessories such as manometer blocks, booster modules, and limit switches. With its versatile thread connections (1/2" NPT electrical, 1/4" NPT pneumatic), it is ready for direct mounting or remote configurations.

Overview

The SIPART 6DR5223-0EN00-0AA0 PS2 controls valve position based on setpoint input, providing online and offline diagnostics to monitor and optimize system performance. Diagnostic capabilities can be enhanced with optional pressure sensors for comprehensive condition monitoring.

Design

This digital positioner consists of:

• Base plate with lid (optional inspection window)
• Electronics supporting 4–20 mA, HART, PROFIBUS PA, and FOUNDATION Fieldbus
• Position feedback through potentiometer or NCS
• Pneumatic block for air supply and actuation

Connection points for additional components like gauge blocks, boosters, and safety valves are integrated on the enclosure’s right side. The SIPART PS2 mounts directly to the actuator via an appropriate kit.

Optional Expansion

Modules and functions available for expansion:

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

All signals are electrically isolated and the modules are retrofittable, offering flexibility for varied industrial requirements.

Separate Mounting

For harsh environments, SIPART PS2 can be mounted separately from the valve, with stroke/angle detection remaining at the actuator. This setup improves reliability when facing vibration, radiation, or extreme conditions.
