Description
The ABB CI869K01 3BSE049110R1 Communication Interface Module is an AC 800M communication interface designed for ABB System 800xA automation platforms. It provides connectivity between AC 800M controllers and ABB Advant Fieldbus 100 (AF 100) networks, enabling data exchange with legacy ABB Advant Master systems and other compatible control nodes.
The CI869K01 package includes the CI869 communication interface module and TP869 baseplate. It integrates CEX-Bus logic, communication electronics, and a DC/DC converter, allowing direct connection to the AC 800M controller system. The module supports redundant communication configurations and is widely used in process industries requiring reliable DCS communication.
This module is commonly applied in power generation, oil & gas, chemical processing, water treatment, and other industrial automation environments where ABB System 800xA and Advant Fieldbus 100 communication infrastructure is installed.
