Description
Product Introduction & Engineering Value
Replacing an FBM203 without disturbing the RTD field wiring is a common maintenance requirement. The P0916AEOC is a compression-type Termination Assembly in the same family as the P0916AE, designed for the Foxboro FBM203 eight-channel RTD input module.
It provides secure landing points for platinum and nickel RTDs and allows the module to be swapped while the field wiring remains connected. The “OC” suffix indicates a specific revision or option within the P0916AE family; functional behavior remains that of a passive compression TA matched to the FBM203. The assembly mounts with the standard 200 Series baseplate system and connects via the termination cable.

Field Application & The “Trench” Experience
A Gulf Coast polymer plant needed to replace a failing that monitored eight jacket and feed-line RTDs. The existing P0916AEOC Termination Assembly was left in place. The old module was removed, a tested installed, and the termination cable reconnected. All eight temperature points returned with no re-landing of field wires and no measurable offset after verification against a precision resistance source.
Typical niche applications:
- Field termination for RTD input channels in process temperature monitoring
- Maintenance interface that permits module replacement without disturbing RTD wiring
- Legacy or active I/A Series installations using the and matching compression TA (P0916AE / P0916AEOC family)

Transparency SOP: QA & Testing
- Visual inspection of housing, terminals, connectors, and original P0916AEOC labeling.
- Continuity verification of all terminal-to-connector paths.
- Mechanical fit confirmation with a known-good and termination cable.
- Inspection for cracked housings, damaged or corroded terminals, and wear.
- Basic isolation check between channels and to ground where applicable.
The Veteran’s Tech Trap Guide
⚠️ Confirm the exact suffix required by your system. P0916AEOC is a variant of the P0916AE family. While functionally aligned with the , always cross-check the original bill of materials or system drawings to ensure the “OC” version is the correct match for your installation.
PRO TIP: When working with 3-wire RTDs, double-check lead landing. A swapped compensation lead introduces a fixed temperature offset that can be missed during quick online checks.
⚠️ Do not assume interchangeability with other RTD or analog TAs. This assembly is matched to the . Using it with a different module can produce incorrect wiring or loss of proper lead compensation.
Dynamic FAQ
Q: What module is the P0916AEOC designed for? A: It is a compression-style Termination Assembly in the P0916AE family, matched to the Foxboro 8-channel RTD input module.
Q: How does differ from ? A: is a specific revision or option variant within the same Termination Assembly family. Functional purpose remains the same—passive compression termination for the .
Q: Is the an active or passive device? A: It is a passive termination assembly. It provides wiring termination and connection only.
Q: Can the be replaced without lifting field wires when using this TA? A: Yes. That is one of the primary advantages of the Termination Assembly design.
Q: Are New Surplus units original Foxboro product? A: Yes. Units are original OEM material that have passed visual, continuity, and mechanical fit testing.
Q: What warranty is provided? A: 12-month warranty against defects in materials and workmanship from the date of shipment for both New Surplus and fully tested refurbished units.
