Product Overview

ABB TU811V1 is a 16-slot I/O electronic rack (base plate) specially designed for S800 I/O systems, supporting vertical installation. It can accommodate up to 16 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 TU811V1 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.
