Emerson 3D39861G01 HART® Protocol Electronics Card Stack

FAQ

Q1: What is the Emerson 3D39861G01 used for?
A: The 3D39861G01 is the main electronics assembly for the Rosemount Oxymitter 4000. It processes oxygen measurement signals, manages transmitter functions, and provides HART communication for configuration and diagnostics.

Q2: Which instruments are compatible with the 3D39861G01?
A: It is specifically designed for the Rosemount™ Oxymitter 4000 Oxygen Transmitter and should be installed only in compatible analyzer models.

Q3: Does the 3D39861G01 support HART communication?
A: Yes. The electronics assembly supports the HART® protocol, allowing remote configuration, diagnostics, calibration, and process monitoring through compatible asset management systems.

Q4: Is the 3D39861G01 a complete oxygen analyzer?
A: No. It is an internal electronic assembly that operates as part of the Rosemount Oxymitter 4000 oxygen transmitter and cannot function independently.

Q5: What output signal does the 3D39861G01 provide?
A: When installed in a compatible transmitter, it supports a 4–20 mA analog output with HART digital communication, enabling integration with PLC, DCS, and process control systems.

Q6: What are the dimensions and weight of the 3D39861G01?
A: The approximate dimensions are 180 × 120 × 40 mm, and the weight is approximately 0.23 kg. Actual values may vary slightly depending on the hardware revision and packaging.

Q7: Can the 3D39861G01 replace other Oxymitter electronics boards?
A: Replacement should only be performed after verifying the complete part number, hardware revision, and compatibility with the installed Oxymitter 4000 transmitter to ensure proper operation.

Q8: What should be checked before installing the Emerson 3D39861G01?
A: Verify the part number, transmitter model, connector condition, firmware compatibility, and power isolation. Follow Emerson installation procedures and perform a functional check after replacement to confirm proper oxygen measurement and HART communication.
