Foxboro FBM233 Field Device System Integrator Redundant Ethernet Communication Module

Product Description

The FBM233 is a FDSI field device system integrator module for Foxboro I/A‑Series DCS platform. This Ethernet‑based gateway realizes protocol conversion and data exchange between 

DCS control database and external Ethernet‑enabled field equipment. It supports Modbus‑TCP and other industrial protocols, capable of connecting up to 64 slave field instruments, VFD 

drives and third‑party controllers. Two FBM233 modules can be deployed in master‑tracker redundant configuration for seamless communication switch‑over upon single‑module failure. 

Designed for Class G3 harsh industrial environment, it is widely used in petrochemical, power generation and chemical plant DCS cabinets, acting as key maintenance spare for legacy 

I/A‑Series system communication channel refurbishment.
