SB822 3BSE018172R1 ABB Electronic rack AC 800M S800 I O Supports 8 I O modules
TU830V1 3BSE013234R1 ABB Electronic rack AC 800M S800 I O Supports 8 I O modules
ABB SB822 is an 8-slot I/O electronic rack (base plate) specially designed for S800 I/O systems, supporting horizontal installation. It can accommodate up to 8 S800 I/O modules (such as DI801, DO810, AI810, AO810, etc.) and provide power distribution and high-speed data communication channels through the built-in ModuleBus bus. The SB822 is mainly used to integrate multiple I/O modules into a compact unit and connect to the AC 800M controller or System 800xA system via the CI801 or CI854A communication interface module.
