ABB CI858K01 / CI858 (3BSE018135R1) — Product Overview
Brand: ABB
Series: AC 800M / System 800xA – DriveBus Communication Interface
Product Introduction
The CI858K01 (also referred to as CI858) is a dedicated DriveBus interface module for ABB’s AC 800M controllers. It facilitates high-speed communication—up to 8 Mbit/s—with ABB drives and special I/O units, making it ideal for systems requiring precision and responsiveness (e.g., rolling mills, paper machines). Powered directly via CEX-Bus from the processor, and supporting hot-swapping, it enables uninterrupted operation in critical environments.
