Built‑in function

FBM10 mixed discrete I/O module undertakes switch‑signal acquisition and logic output for Foxboro I/A‑Series DCS system. It collects 120VAC status signals from field limit switches and auxiliary contacts,and outputs relay contact signals to control solenoid valves and auxiliary relays. It can connect FBM15 expansion module to increase I/O quantity. Hot‑swap supports online module replacement,widely applied for pump,motor interlock‑control‑loop maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

FBM10 belongs to Foxboro I/A Series legacy DCS mixed‑discrete‑I/O spare‑part family,obsolete original baseplate‑mount mixed discrete I/O 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.
