4. Product Introduction
The Foxboro P0916AA is a compression-style field termination assembly designed specifically for the FBM201 Analog Input module in the I/A Series system. It provides a secure, organized interface between field wiring (typically 0–20 mA transmitter signals) and the FBM201 electronics.
Because the TA is a passive device, field wiring can remain connected while the FBM201 module itself is removed or replaced. This design simplifies maintenance and reduces downtime. The compression terminals offer reliable gas-tight connections suitable for industrial environments. The P0916AA is matched electrically and mechanically to the standard FBM201 and is not intended for use with later FBM201b/c/d variants unless confirmed by the system documentation.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No or erratic analog input readings | Loose compression terminals or broken field wire | ✅ High | Check terminal tightness and continuity from field device to TA | Retighten or re-terminate wires; verify shield grounding |
| not recognizing signals | Incorrect wiring or wrong TA for module type | ✅ High | Confirm TA is P0916AA and matched to ; check cable between TA and FBM | Use correct TA; reseat or replace interconnect cable |
| Intermittent signals | Vibration-induced terminal loosening or poor contact | ✅ Medium | Inspect terminals under vibration; check for corrosion | Re-terminate with proper torque; consider strain relief |
| Ground loops or noise | Improper shield termination | ✅ Medium | Verify single-point shield grounding practice | Correct shield termination per Foxboro guidelines |
| Difficulty removing FBM | Mechanical interference or damaged connector | ✅ Low | Inspect connector pins and TA alignment | Ensure proper alignment; replace damaged connector if needed |
If diagnostics remain unclear, capture wiring diagrams, continuity measurements, and photos of the TA and FBM installation, then contact technical support with the exact part numbers.
6. Frequently Asked Questions (FAQ)
Q: What is the used for? It is the compression termination assembly that connects field wiring to the Foxboro 8-channel analog input module (0–20 mA).
Q: Is the an active electronic module? No. It is a passive termination assembly. All signal conditioning and A/D conversion occur in the module itself.
Q: Can I use the with FBM201b, FBM201c, or FBM201d? It is specified for the standard . Compatibility with later variants should be confirmed against the official Foxboro documentation for your system revision.
Q: Can the be replaced without disconnecting field wiring? Yes. That is one of the primary advantages of the termination assembly design. The field wires stay on the TA while the FBM is removed.
Q: Why is new surplus pricing lower than current list? These are genuine OEM assemblies from excess or decommissioned stock. They have not been installed in continuous service. Every unit undergoes inbound inspection before shipment. Test reports are available on request.
Q: What cable connects the to the ? A Type 4 (or system-specified) termination cable is typically used. Maximum recommended length is usually 30 m (98 ft). Always follow the cable type and length guidelines in the product specification.
