Built‑in function

AW51B application workstation node acts as core hardware node for Foxboro I/A‑Series DCS system. It communicates with field control processors via Nodebus network,completes mass process‑data receiving,alarm event sorting and caching. It provides stable data source for upper‑level operator screens and report functions. Built‑in self‑diagnosis circuit monitors hardware running status,LED feedback facilitates on‑site fault inspection,widely applied for petrochemical,chemical and power‑plant DCS monitoring workstation hardware.

Product Brief

AW51B belongs to Foxboro I/A‑Series legacy DCS workstation spare‑part family,obsolete original node hardware component. Must match dedicated I/A‑Series node baseplate and Nodebus network wiring. Widely used for original Foxboro DCS‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation
