4. Product Introduction
The Foxboro P0916XG is a DIN-rail mounted termination assembly used with the FBM201 8-channel 0–20 mA analog input module in the I/A Series DCS. It provides the organized field wiring interface between process transmitters and the Fieldbus Module.
Engineers select the P0916XG when they need a genuine OEM terminal base that allows FBM replacement without disturbing field cables and maintains the original signal integrity for analog current loops. Correct pairing with the FBM201 keeps the installation within the designed isolation and accuracy envelope for process variable acquisition.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No analog signal from channels | Open or high-resistance connection at TA terminals | ✅ High | Continuity check from field device to TA terminals; verify torque | Re-terminate wires; confirm correct wire gauge and ferrules |
| Intermittent or noisy readings | Loose terminals, oxidation, or poor shield termination | ✅ High | Visual inspection + live wiggle test while monitoring values | Clean contacts, re-torque, ensure proper single-point shield grounding |
| All channels dead after TA swap | Wrong TA type or cable mis-seated | ✅ High | Confirm part number P0916XG matches documentation | Install only the correct TA; reseat termination cable |
| Ground loop or common-mode errors | Improper shield/ground connection at TA | ✅ Medium | Measure voltage between shield and ground | Correct grounding per I/A Series guidelines |
| Physical damage or cracked housing | Mechanical stress or incorrect DIN-rail installation | ✅ Medium | Visual inspection of housing and mounting clips | Replace the TA; do not attempt field repair |
| FBM reports channel faults | Field device voltage/current outside range or wiring error | ❌ Low (usually field or FBM side) | Measure actual loop current at TA terminals | Verify transmitter and FBM configuration first |
If symptoms persist, capture FBM diagnostic buffer data, photograph the TA wiring and part number, and contact technical support with the information.
6. Frequently Asked Questions (FAQ)
Q: Is the P0916XG the actual module? A: No. It is the termination assembly. The is the analog input module that connects to this TA via cable.
Q: What signals does the P0916XG support? A: It is designed for the ’s eight 0–20 mA analog input channels (compatible with standard 4–20 mA transmitters). Isolation and conversion are handled by the FBM.
Q: Can I hot-swap the FBM while using this TA? A: Yes. The design allows removal and replacement of the without disconnecting field wiring attached to the P0916XG, provided plant procedures permit it.
Q: Why is this unit priced lower than a factory-new order? A: This is New Original / New Surplus stock. It is genuine Foxboro material that has not been installed in continuous service and carries functional verification. It is not refurbished.
Q: Do I need to reconfigure anything when replacing the TA? A: No. The is a passive wiring interface. Scaling, filtering, and diagnostics remain in the and the control processor. Match the terminal wiring to your existing drawings.
Q: What is the warranty and typical lead time? A: Standard coverage is 1 year. Units are normally in stock and ship within a few business days. Confirm current availability when ordering.
Q: Is this part still supported? A: The remains in use across existing I/A Series installations for applications. Always verify against your system drawings, as some related part numbers have supersessions in later documentation.
