TB820V2 ABB I/O electronic frame base plate AC 800M S800 I O
The ABB TB820V2 is a standard 8-slot I/O electronic frame (also known as the base plate or back plate) for the S800 I/O system, specifically designed for vertical installation. It is used to support and connect up to 8 S800 series I/O modules (such as DI801, DO810, AI810, AO810, etc.). It provides power distribution and high-speed data communication channels for the module through the built-in ModuleBus bus, and connects to the CI801 (electrical) or CI854A (optical fiber) communication interface module via a dedicated interface, thereby accessing the AC 800M controller.
