Product Overview

The P0916TQ (FCM2F10) is Foxboro I/A‑Series single‑mode fiber fieldbus communication module. It converts electrical fieldbus signal into optical signal, extending long‑distance noise‑immune communication between main control processor FCP and remote FBM I/O nodes. It breaks ground‑loop interference over long cable runs in heavy‑EMI power‑plant and petrochemical plant environments. Supports redundant dual‑bus deployment for high‑availability DCS cabinets. It is installed on FCM baseplate rack, provides reliable optical transmission for distributed I/O data exchange.

This module solves long‑distance DCS communication challenges: single‑mode fiber long‑haul fieldbus extension, strong EMI rejection for industrial plant cabinets, drop‑in spare‑part compatibility for legacy I/A‑Series retrofit‑maintenance projects. DCS control engineers, power‑plant & petrochemical‑site maintenance technicians and retrofit integrators benefit most. Typical applications: utility power‑plant, oil‑gas refinery DCS remote I/O cabinet fiber‑link communication.

Key Application Notes

‑Must install on matched FCM baseplate rack; cannot operate standalone; pair with FCP controller and remote FBM I/O modules ‑Uses single‑mode LC‑duplex fiber, multi‑mode fiber is not compatible, will cause link failure ‑Supports redundant A/B fieldbus; proper bus‑termination resistor must be fitted at bus end‑points ‑Not hot‑swap capable: rack 24 VDC power must be cut off before module replacement ‑Original OEM production discontinued; widely‑used aftermarket surplus/refurbished spare part ‑Conformal‑coated variant available for high‑humidity, corrosive cabinet environments ‑Follow Foxboro I/A‑Series FCM2F10 official manual for fiber‑link budget calculation and commissioning
