Built‑in function

FBM212 high‑density thermocouple‑millivolt input module converts field‑side thermocouple differential sensor signals to digital process data for Foxboro I/A‑Series DCS system. It integrates RTD cold‑junction compensation for accurate temperature calculation. It adopts group‑isolation architecture rather than per‑channel isolation. Open‑circuit detection quickly identifies broken thermocouple wiring faults. Hot‑swap supports online module replacement without system shutdown,widely applied for furnace,heater,reactor and thermal‑equipment‑monitoring‑loop maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM212 belongs to Foxboro I/A Series legacy DCS high‑density‑thermocouple‑input spare‑part family,obsolete original baseplate‑mount 14‑channel thermocouple‑millivolt acquisition module component. Must match with corresponding FBM baseplate,P0916BV termination assembly and matched cable assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
