Built‑in function
FBM10/15 mixed discrete I/O module collects AC switch‑status signals and outputs relay‑contact control signals for Foxboro I/A‑Series DCS system. It is pre‑configured to cooperate with FBM15 expansion assembly to expand I/O quantity. Isolated‑channel design improves anti‑interference performance in complex industrial cabinet environment. Hot‑swap supports online module replacement,widely applied for pump,motor interlock‑control‑loop maintenance in petrochemical,chemical and power‑plant facilities.
Product Brief
FBM10/15 belongs to Foxboro I/A Series legacy DCS mixed‑discrete‑I/O spare‑part family,obsolete original baseplate‑mount mixed discrete I/O module component. Must match with corresponding FBM baseplate and FBM15 expansion assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
