Product Details
The Foxboro P0700AB, also cataloged as the P0700AB Termination Assembly, operates as a dedicated hardware component for field signal termination and I/O bus interface routing within Foxboro I/A Series DCS networks. It provides structured physical termination points to interconnect field instrumentation signals directly to corresponding Field Bus Modules (FBMs) across system cabinets.

Channel-to-Channel Isolation and Loop Diagnostics
The Foxboro P0700AB incorporates channel isolation trace geometry designed to eliminate ground loops and common-mode noise across industrial field loops. By isolating field-side instrumentation connections from backplane logic power, the assembly maintains signal accuracy for 4-20 mA HART loop protocol transmitters and discrete I/O devices operating in harsh electromagnetic environments.
Frequently Asked Questions
Q: Does the P0700AB termination assembly require an external power supply to operate?
A: No, the P0700AB is a passive signal routing termination unit that transfers signals and loop power directly between field devices and the system I/O module.
Q: Can the P0700AB be used with non-redundant and redundant FBM configurations?
A: Yes, the assembly supports standard Foxboro I/A Series cabling interfaces for direct connection to single or redundant Field Bus Module card sets.
Field Installation Guidelines
Mount the P0700AB securely onto the cabinet DIN rail or baseplate framework. Ensure field wiring leads are properly stripped, inserted into designated terminal blocks, and torqued to manufacturer specifications to guarantee gas-tight electrical contact.
Maintain physical separation between high-voltage power wiring and low-voltage fieldbus or analog signal lines. Connect all instrument cable drain shields to the enclosure grounding bar at a single point. When passing cables through enclosure entry points, ensure NPT conduit fittings achieve a minimum of 5 full threads of engagement to preserve panel seal integrity.
