Description
The ABB CI858K01 3BSE018135R1 DriveBus Interface Module is a communication interface unit designed for ABB AC 800M controller systems. It provides a dedicated DriveBus connection between ABB drives and the AC 800M controller, enabling high-speed communication for drive control, monitoring, and automation applications.
The CI858K01 is widely used in ABB System 800xA automation environments, especially in applications requiring coordinated drive control such as rolling mills, paper machines, and large industrial production lines. The module supports ABB DriveBus protocol communication and can connect multiple ABB drives through the CEX-Bus architecture.
The module package includes the CI858 communication interface and TP858 baseplate. It is powered through the AC 800M processor unit via the CEX-Bus and does not require an additional external power supply.
