Built‑in function

FBM03 RTD input module acquires high‑precision temperature signals from field RTD sensors for Foxboro I/A‑Series DCS system. Isolated‑channel design suppresses ground‑loop interference. Open‑circuit diagnosis rapidly identifies broken sensor wiring faults. Hot‑swap supports online module replacement,widely applied for tank,reactor and pipeline temperature monitoring loops in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM03 belongs to Foxboro I/A Series legacy DCS temperature‑input spare‑part family,obsolete original baseplate‑mount RTD 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.
