ABB CI855 3BSE018106R1 MasterBus 300 Communication Interface Module

Description

The CI855 enables high-speed communication between the AC 800M CPU and Advant Controller 400 or MB 300 nodes. It mounts on the CEX-Bus, draws internal power, and has a compact design. Ideal for phased upgrades or hybrid control systems, it allows centralized management of multiple controller generations.
