ABB SC520 is a submodule carrier with a local CPU used in ABB’s AC800PEC distributed control system. It is a modular building block used to expand the system’s I/O and processing capabilities.
The main features of ABB SC520:
Modular design: The modular design of SC520 allows for the addition or removal of sub modules as needed, enabling flexible system expansion.
Local CPU: It contains a local CPU that can independently process I/O signals and control tasks, reducing the load on the main controller.
I/O Expansion: SC520 can accommodate various I/O submodules, supporting various signal types and communication protocols.
Hot swapping: It allows for hot swapping of submodules without interrupting system operation, improving maintainability.
