Built‑in function

FBM220 communication interface module serves as Modbus gateway for Foxboro I/A‑Series DCS system. It completes protocol conversion between DCS fieldbus and Modbus RTU bus,realizes data interaction with third‑party Modbus instruments,transmitters and frequency converters. Built‑in communication fault diagnosis helps locate bus wiring and slave‑station exceptions. Hot‑swap supports online module replacement without system shutdown,widely applied for accessing multi‑vendor field devices in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM220(P0917HA) belongs to Foxboro I/A Series legacy DCS standard‑200‑series‑communication‑interface spare‑part family,obsolete original Modbus RTU gateway module component. Must match with Standard‑200‑series dedicated baseplate and termination assembly. Not interchangeable with Compact‑200‑series hardware. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
