ABB CI820 3BSE013200R1 Redundant Communication Interface

Product Overview

The CI820 (Part No: 3BSE013200R1) is a high-reliability communication interface designed for the S800 I/O system. It provides redundant communication paths between the I/O cluster and the AC 800M controller, ensuring continuous data flow even if a cable or interface fails. This module is critical for high-availability industrial processes where unplanned downtime must be eliminated.
