CI869 3BSE049110R1 ABB AF 100 Fieldbus Communication Interface Module

The ABB CI869 communication interface module connects AC 800M controllers to the AF 100 fieldbus network using a twisted-pair interface. The AC 800M controller equipped with CI869 operates as an AF 100 station, receiving and exchanging data with other AF 100 stations and devices.

The module includes CEX-Bus logic, a communication unit, and a DC/DC converter that supplies the required voltage from the +24 V supply through the CEX-Bus, requiring no additional external power source. It supports redundant cable configuration and redundant communication interface setup, and can also be used in AC 800M High Integrity systems.
