ABB CI856/3BSE026055R1
The ABB CI856/3BSE026055R1 module is a communication system module from ABB that is commonly used for communication interfaces in industrial automation systems. It supports ABB S100 I/O master-slave relationship, has heat exchange function and can be used with HI controller 12. The CI856 is powered by the processor unit via the CEX bus, so no additional external power supply is required.
A key benefit of using the CI856 interface is the ability to incorporate most existing I/O installations, including terminals and field cabling in existing ABB Master and future OCS installations.12
