Siemens 6DR5220-0EG01-0AA0 SIPART PS2 Smart electropneumatic positioner, 4-20 mA/HART, double-acting

Siemens 6DR5220-0EG01-0AA0 is documented for the stated industrial system role: Regulates a double-acting pneumatic actuator from a 4-20 mA/HART command and provides the documented analog position-feedback path.

System function

Rebuilt from individual evidence

System position

Siemens identifies 6DR5220-0EG01-0AA0 as a SIPART PS2 Smart electropneumatic positioner for 4-20 mA/HART operation on double-acting pneumatic linear and part-turn actuators.

The Siemens product description specifies intrinsic-safety Ex i protection, a polycarbonate enclosure, M20x1.5 electrical and G1/4 pneumatic connections, and an analog 4-20 mA position-feedback module.

Regulates a double-acting pneumatic actuator from a 4-20 mA/HART command and provides the documented analog position-feedback path.

The system position is an explicit inference from the exact-reference evidence.

Unknown: installation-specific actuator sizing, air quality, HART configuration, certification conditions, and current service status.

System role

This section explains what the product does and where it acts in the surrounding system.

Function: Regulates a double-acting pneumatic actuator from a 4-20 mA/HART command and provides the documented analog position-feedback path.
System position: Sits between the controller loop and the pneumatic actuator in the valve-positioning path.
Upstream / inputs: Receives the controller's 4-20 mA/HART command and the pneumatic supply for the actuator.
Downstream / outputs: Controls both actuator directions and exposes the documented 4-20 mA analog position feedback.
Limitations: Unknown: installation-specific actuator sizing, air quality, HART configuration, certification conditions, and current service status.

Inferences

Inferred system position: Sits between the controller loop and the pneumatic actuator in the valve-positioning path.
Confidence: high
Rationale: The exact-reference sources establish the product identity and documented interfaces; their relationship to the stated upstream and downstream elements is marked as an inference.
