Frequently Asked Questions (FAQ)

Q1: What is the Siemens 6DR5120-0NG01-0AA2?

It is a SIPART PS2 smart electropneumatic positioner for double-acting pneumatic actuators. It operates on a 2-wire, 4–20 mA signal with HART communication and includes an Analog Output Module (AOM) for 4–20 mA valve position feedback .

Q2: What is the difference between the 6DR5120 and 6DR5110?

The 6DR5120 is for double-acting actuators (no return spring). The 6DR5110 is for single-acting actuators (with return spring). They are not interchangeable .

Q3: What does the "01" in the part number indicate?

The 01 position in the code indicates the presence of the Analog Output Module (AOM), which provides 4–20 mA analog position feedback. The "00" variant does not include this module .

Q4: Is this positioner explosion-proof?

No. The 0AA2 suffix indicates a standard, non-explosion-proof polycarbonate enclosure. For hazardous areas, the 0EA0 (Ex i intrinsically safe) or other Ex-rated variants should be selected .

Q5: What is the input signal and wiring?

The positioner uses a 2-wire connection: the same two wires carry both the 4–20 mA control signal and the power for the electronics. HART communication is superimposed on this signal .

Q6: What is the position feedback signal?

The integrated AOM provides a 4–20 mA output proportional to the valve position, allowing the control system to monitor actual valve travel .

Q7: What are the pneumatic connections?

Electrical connection is M20 × 1.5. Pneumatic connection is G 1/4 .

Q8: What is the protection class?

The positioner is rated IP66 / NEMA 4X .

Q9: What is the operating temperature range?

The standard range is -30 to +80 °C .

Q10: What is the net weight and country of origin?

Net weight is 1.570 kg. Country of origin is China .

Q11: Does this positioner support HART communication?

Yes. HART communication is integrated, allowing configuration and diagnostics via SIMATIC PDM or a HART handheld communicator .

Q12: What should I verify before ordering?

Always verify the exact part number (6DR5120-0NG01-0AA2), confirm your actuator is double-acting (not single-acting), ensure the application does not require explosion protection, and check whether the 4–20 mA analog feedback (AOM) is needed for your control system .
