Foxboro P0926MX I/O Termination Assembly for I/A Series FBM2xx – Clean, reliable field wiring interface

From my experience with the Foxboro I/A Series, part numbers in the P0926xx family are the workhorse termination assemblies (TAs) that sit between your field wiring and the FBM2xx modules. The Foxboro P0926MX follows that pattern: a passive, cabinet‑mounted interface that keeps marshalling tidy, shields managed, and loop checks straightforward. You might notice that projects typically use these when they want a predictable, maintainable landing point for AI/DI/AO/DO wiring without adding active electronics at the terminal rail.

Key Features

• Purpose‑built TA for FBM2xx – Provides the field wiring interface for Foxboro FBM2xx I/O modules, minimizing cabinet complexity.
• Passive design – No separate power required; typically lowers failure risk and simplifies spares strategy.
• Clean marshalling – Labeled channels and organized terminal layout help with loop checks and FAT/SAT documentation.
• Grounding and shield management – Typically includes bonding points to keep noise under control in mixed‑signal cabinets.
• DIN‑rail or panel mounting – Fits standard 35 mm DIN rails; compact footprint for crowded control panels.
• Field‑proven with mixed I/O – Works with the corresponding FBM type (AI/DI/AO/DO); the TA does the termination, the FBM does the electronics.
• Serviceable wiring – Technicians usually appreciate the accessible terminals and straightforward replacement process.

Technical Specifications

Related or Supporting Products

• FBM201 / FBM207 / FBM223 series – Common Foxboro I/A Series FBM modules (AI/DI/DO variants) that pair with P0926xx termination assemblies.
• Foxboro P0926AJ / P0926HC family – Other TA variants in the same series; typically differ by terminal style, channel mapping, or FBM compatibility.
• Shield/earth bars and marshalling accessories – Useful for tidy shield management and segregation of IS/non‑IS circuits.
• Pre‑labeled wire ferrules – Speeds up loop checks and reduces wiring errors during commissioning.

A maintenance supervisor on a recent retrofit told me the P0926‑series TAs made their weekend cutover smoother; they re‑landed loops by channel label, then plugged the FBMs on Monday with minimal rework. That seems to be the typical experience when cabinets are tight on space and time.

Installation & Maintenance

• Cabinet environment: Install on 35 mm DIN rail inside a ventilated, dry control cabinet. Keep low‑level analog separate from high‑energy or solenoid wiring where possible.
• Grounding/shielding: Bond cable shields at the designated points. In most cases, single‑end grounding reduces noise; follow site EMC practices.
• Wiring: Use correctly sized conductors and ferrules. Torque terminals per Foxboro guidance; avoid over‑tightening spring or screw clamps.
• Clearances: Allow room for cable bend radius and for service access to terminal screws and labels.
• Safety: De‑energize affected loops before landing or removing conductors. Tag circuits; verify isolation especially on DO/relay circuits.
• Routine checks: Periodically re‑torque terminals, inspect for discoloration or loose conductors, and clean dust with dry air (no solvents).
• Documentation: Keep channel maps synchronized with your DCS configuration so the TA labels match FBM assignments.

Quality & Certifications

• Certifications: Foxboro hardware is typically compliant with CE marking and recognized by UL/CSA. RoHS conformity is common across modern builds.
• Manufacturing quality: Produced under ISO 9001 quality management systems.
• Manufacturer’s warranty: Standard manufacturer policy applies; we additionally support a 365‑day warranty on supply.

If you’re matching the P0926MX to a specific FBM, share the FBM model and channel count—there are subtle TA differences (terminal style, mapping) that matter at commissioning. One thing I appreciate is how consistent Foxboro keeps the wiring conventions across the P0926 family, which typically makes like‑for‑like replacements quicker than you’d expect.
