Overview

The ABB CI522A is part of the Advant Controller communication suite, engineered to support redundant AF100 fieldbus communication. Acting as a bridge between the controller and distributed I/O systems, it enables real-time data exchange and fault-tolerant performance in critical industrial processes. This module is essential for applications requiring high availability and robust control reliability.

Moreover, the CI522A supports dual-channel redundancy, ensuring uninterrupted data transmission even during network or hardware failures. Its compact and modular design simplifies installation and maintenance. In addition, the module adheres to industrial compliance requirements and is RoHS-exempt under specific EU directives, allowing deployment in legacy upgrade scenarios.

For instance, in a chemical processing plant, the CI522A can maintain continuous control signal flow between the central controller and field devices, even during maintenance or partial bus outages.
