Product Details

3BSE005461R1,type DSPC174,is memory processor board for ABB Master System DCS control rack. It stores user application programs and caches real‑time process data,completes high‑speed data interaction through rack backplane bus,assists main controller for logic calculation.

Adopts multi‑group on‑board memory chip layout,front‑panel LED reflects power‑on,running and fault state. Rack plug‑in structure for convenient disassembly and maintenance. Board failure will cause program loss,system startup failure or bus communication abnormality. Widely used for old‑generation Master System DCS on‑site overhaul and spare‑part replacement.

Note:This is legacy EOL spare component,widely used for DCS system spare‑part replacement.
