FBM231 | Foxboro | Field Device System Integrator Module

Description

The FBM231 is a Field Device System Integrator (FDSI) Module from Foxboro, designed to connect multi-port field I/O devices to the Foxboro Evo system, and it belongs to the FBM230 product series (which also includes models like the single-port Ethernet interface FBM230 P0926GU). It features 4 independently configurable RS-232, RS-422, or RS-485 ports, supporting up to 64 connected field devices, making it suitable for applications requiring integration of diverse on-site equipment into the Foxboro Evo system. As a redundant-capable module, a pair of FBM231 units can provide field bus module (FBM) level redundancy: one acts as the Master and the other as the Tracker, with automatic role switching triggered by detected issues such as heartbeat failures, or manual switching via SMDH. Key technical specifications include a 24 V DC power supply with 7 W power consumption, an operating temperature range of -20 degrees Celsius to 70 degrees Celsius, an IP65 protection rating, dimensions of 102 mm x 114 mm x 104 mm, and a weight of 284 g. The module carries CE, ATEX, and CSA certifications, with the part number P0926GV.
