Product Details
57520001‑EV,type DSCS140,is MasterBus300 communication processor for ABB Advant series DCS system.
It undertakes data gateway function between upper‑level controller and S100 I/O racks,adopts proprietary MasterBus300 protocol with 2Mbps rate,realizes real‑time interaction of analog/digital signals between controller and I/O modules;supports communication redundancy to improve system reliability. Rack plug‑in structure,equipped with multi‑group LED for running status and fault diagnosis. Module failure will cause corresponding S100 I/O rack offline,loss of all I/O signals of the whole rack. Widely used for legacy Advant DCS site maintenance.
Note:This is legacy EOL spare component,widely used for process industry spare‑part replacement.
