4. Product Introduction
The Foxboro P0916AG is a compression-style Field Terminal Assembly designed specifically for the FBM204 intelligent Fieldbus Module in Foxboro I/A Series and EcoStruxure Foxboro DCS systems. It provides the physical interface between field wiring and the FBM204, handling four analog input and four analog output channels in the 0–20 mA / 4–20 mA range.
Technicians use this assembly when they need reliable, gas-tight terminations that minimize noise and maintain signal integrity for process measurements and control outputs. It is a direct-fit replacement for existing I/A Series installations that rely on the FBM204.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No signals from field devices | Loose or corroded terminals | ✅ High | Inspect and retighten all compression terminals | Clean and re-torque connections before replacing FTA |
| Intermittent or noisy 4–20 mA | Poor contact or ground loop | ✅ High | Measure continuity and check shield grounding | Verify proper shield termination; replace FTA if contact resistance is high |
| FBM204 reports open channel | Broken wire or open terminal | ✅ Medium | Continuity test from field device to FTA pins | Repair field wiring first; FTA rarely fails open |
| All channels fail simultaneously | Cable or FBM204 fault | ❌ Low | Swap FBM204 or test with known-good cable | FTA is passive; issue is almost always upstream |
| Physical damage / cracked housing | Impact or over-torque | ✅ High | Visual inspection of terminal block | Replace FTA if housing is cracked or terminals deformed |
| High contact resistance | Oxidation or improper wire size | ✅ High | Measure millivolt drop under load | Clean terminals or replace FTA |
If problems continue after checking wiring and the FBM204 itself, send photos of the terminal block and any diagnostic messages to technical support.
6. Frequently Asked Questions (FAQ)
Q: Is the P0916AG the terminal assembly for the FBM204?
A: Yes. It is the dedicated compression terminal assembly that provides the field wiring interface for the FBM204’s four analog inputs and four analog outputs.
Q: Can I use this with other FBM modules?
A: No. The P0916AG is specifically designed for the FBM204. Other FBM modules use different terminal assemblies (for example, P0916AE, P0916AJ, etc.).
Q: Does it include the FBM204 module?
A: No. This is only the Field Terminal Assembly. The FBM204 electronics module is a separate part.
Q: What wire size does the compression terminal accept?
A: Standard industrial control wiring (typically 14–22 AWG). Always follow the Foxboro installation manual for exact wire size and torque specifications to avoid damaging the terminals.
Q: Why is new-surplus pricing lower than factory list?
A: These units come from excess project inventory. They are unused, original Foxboro product, tested, and carry a 1-year warranty. They are not refurbished or repaired units.
Q: Do I need special tools to install it?
A: A standard screwdriver for the compression terminals is sufficient. Take a photo of the old wiring layout before disconnecting anything, then transfer the wires one-for-one.
Q: Will this work in a Foxboro Evo system that still uses FBM204 modules?
A: Yes. As long as the system is still using the FBM204, the P0916AG remains the correct terminal assembly.
