Built‑in function

:E20S‑V2FB6 fieldbus expansion module expands fieldbus communication capacity for legacy Foxboro I/A‑Series DCS system. It realizes extension of fieldbus trunk to access more remote FBM I/O stations. Hot‑swap function supports online module replacement and reduces plant downtime risk. Status LED facilitates on‑site communication fault diagnosis,widely applied for subsystem capacity‑expansion and communication‑link maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

E20S‑V2FB6 belongs to Foxboro I/A Series legacy DCS fieldbus‑expansion spare‑part family,obsolete original baseplate‑mount expansion 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.
