Built‑in function

D0137AV processor circuit board adopts AMD bipolar slice processor architecture,executes microprogram‑based arithmetic and logic processing for early‑generation Foxboro I/A‑Series DCS control node. It completes underlying instruction decoding,logic operation and data interaction with system backplane bus. Gold‑plated edge‑connector guarantees stable signal transmission under cabinet vibration environment. Power‑on self‑test circuit completes hardware initialization detection after power‑on,widely applied for legacy I/A‑Series controller hardware replacement and maintenance in petrochemical,chemical and power‑plant facilities.

Product Brief

D0137AV belongs to Foxboro I/A Series legacy DCS processor‑board spare‑part family,obsolete original rack‑inserted circuit‑board component. Must be fitted in matching I/A‑Series instrument rack slot. Widely used for original Foxboro DCS equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation and handling of bare circuit board.
