Built‑in function

FBM08 120VAC discrete input module collects AC‑type switch status signals for Foxboro I/A‑Series DCS system. It supports SOE sequence‑of‑event monitoring to record time‑stamped switch actions for fault post‑mortem analysis. It can connect an expansion module to increase I/O quantity. Hot‑swap supports online module replacement,widely applied for pump,motor interlock‑signal acquisition loops in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM08 belongs to Foxboro I/A Series legacy DCS discrete‑input spare‑part family,obsolete original baseplate‑mount 120VAC input 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.
