ABB SC520 (3BSE003816R1) is a dedicated submodule carrier with integrated local CPU, developed for ABB AC400 and Advant OCS DCS platforms. It functions as both a controller and an I/O expansion base, supporting up to multiple MB300/MB300E submodules for digital/analog input/output, communication, and special function modules.

Equipped with a built-in local CPU, the SC520 delivers autonomous control capabilities while maintaining seamless communication with the main system controller. Its compact 3U form factor (291 mm × 300 mm × 30 mm) allows for efficient cabinet layout, and the robust construction ensures resistance to vibration, temperature fluctuations, and electrical noise.

Designed for easy installation and maintenance, the unit features a plug-in design for submodules, hot-swap compatibility for supported modules, and LED status indicators for power, CPU activity, and communication. The SC520 complies with RoHS, CE, and industrial safety standards, ensuring long-term reliability in demanding industrial environments. For marine or harsh coated environments, the SC520M (3BSE016237R1) variant is available.
