ABB CI857K01/CI857 3BSE018144R1 AC 800M Communication Interface Module

The ABB CI857K01 / CI857 3BSE018144R1 is a communication interface module used within the AC 800M control system to enable integration with ABB’s INSUM system. This module allows the AC 800M controller to communicate with intelligent switchgear devices using ABB’s proprietary INSUM protocol over Ethernet. Designed for robust industrial environments, it supports multidrop configurations, extended communication distances, and time synchronization functionalities.

It communicates via standard 10 Mbit/s Ethernet, uses an RJ-45 interface, and integrates seamlessly with INSUM Communication Libraries through function blocks. Power is supplied directly from the processor unit over the CEX-Bus, eliminating the need for an external power source.
