Built‑in function

FBM01 thermocouple input module acquires temperature measuring signals from field thermocouple sensors for Foxboro I/A‑Series DCS system. Built‑in CJC cold‑junction compensation ensures accurate temperature reading. Open‑circuit diagnosis helps quickly locate broken thermocouple wiring faults. Hot‑swap function supports online module replacement and reduces plant downtime risk,widely applied for furnace and reactor temperature monitoring loops in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM01 belongs to Foxboro I/A Series legacy DCS temperature‑input spare‑part family,obsolete original baseplate‑mount thermocouple acquisition 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.
