Built‑in functio

FBM05 redundant analog I/O module undertakes high‑reliability analog signal acquisition and output for Foxboro I/A‑Series DCS critical control loops. Two FBM05 modules work in hot‑standby mode;when one unit fails,the other automatically takes over to keep I/O loop running without interruption. Hot‑swap supports online module replacement. Status LED facilitates on‑site redundancy status and fault diagnosis,widely applied for high‑safety valve‑control and process‑monitoring loops in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM05 belongs to Foxboro I/A Series legacy DCS redundant‑I/O spare‑part family,obsolete original baseplate‑mount redundant analog I/O module component. Must match with corresponding FBM baseplate assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
