Built‑in function

FB110E fieldbus isolator implements electrical isolation for 10MB Ethernet fieldbus trunk of Foxboro I/A‑Series DCS system. It eliminates ground‑loop noise caused by potential difference between different cabinet grounding points. Hot‑swap function supports online module replacement and reduces plant downtime risk. Link status LED facilitates on‑site network fault inspection,widely applied for fieldbus network isolation maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

FB110E(P0972AJ) belongs to Foxboro I/A Series legacy DCS communication‑module spare‑part family,obsolete original baseplate‑mount fieldbus isolator component. Must be matched with corresponding FBM baseplate assembly. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
