Description

ABB SC520 (3BSE003816R1) Submodule Carrier with Local CPU for Advant OCS / AC400 Controller System

Product Details

The SC520, part number 3BSE003816R1, is an intelligent submodule carrier board with integrated local CPU for ABB Advant OCS and AC400 controller platforms. This Eurocard‑format rack‑mount module provides dual sub‑slot positions for MB300 / MB300E series communication and I/O sub‑modules, expanding the main controller’s communication and peripheral interface capacity. Equipped with built‑in 32‑bit RISC processor and onboard memory resources, it undertakes local data processing, sub‑module management and distributed data pre‑processing, effectively reducing the computation load of main CPU. It communicates with Advant main controller via backplane bus, supports hot‑swap of installed sub‑modules. Multiple front‑panel LED indicators show power status, running state and fault alarm information. It is an EOL‑obsolete hardware, widely used as spare‑part and retrofit replacement for legacy petrochemical, power and pulp‑paper Advant OCS DCS racks.

Applications

‑ Power plant boiler‑turbine Advant OCS DCS system expansion ‑ Petrochemical and refinery distributed control system interface expansion ‑ Pulp & paper mill legacy AC400 controller peripheral communication extension ‑ Chemical plant process‑control cabinet sub‑module carrier application ‑ Metallurgy industry old‑generation DCS system spare‑part replacement ‑ Water‑wastewater treatment Advant OCS automation retrofit projects ‑ Multi‑protocol communication gateway expansion for Advant controller units
