1. Product Title
Foxboro FEM100 P0973CA‑ Fieldbus Expansion Module for FCP270, I/A‑Series DCS
2. Product Overview
P0973CA (FEM100) is a fieldbus expansion module for Foxboro I/A‑Series DCS, working with FCP270 field control processor. It provides four independent 2 Mbps expanded fieldbus segments, greatly expanding I/O capacity for Compact200 (200‑series) FBM fieldbus modules. Each bus supports up to 32 FBM units, maximum total 128 FBMs for one FCP270. It supports hot‑swap and redundant deployment. It is installed on dedicated expansion baseplate, extending control processor to connect distributed remote I/O racks. Discontinued EOL hardware, used as spare‑part replacement for large‑scale petrochemical, chemical and power‑plant DCS systems.
