FBM230 Product Specification Sheet

1. Product Overview

FBM230 (Part Number: P0926GU) is a 4-port serial communication module (FDSI, Field Device System Integrator) for Foxboro Evo™ and I/A Series DCS systems. It serves as a dedicated gateway to connect the DCS controller with third-party serial devices (e.g., PLCs, variable frequency drives, HART smart instruments, barcode readers). Each port is software-configurable for RS-232/RS-422/RS-485, supporting Modbus RTU/ASCII and HART protocols. With channel-to-channel electrical isolation, low power consumption, and a compact rugged design, it enables flexible, reliable serial data exchange in chemical, power, and manufacturing industries.
