Overview

The ABB CI546 is a communication interface module within the Advant Controller 450RMC series, part of the AC 400 control system family. It functions as a VIP (Versatile Interface Processor) communication bridge, facilitating data exchange between controllers and peripheral devices. This module is essential for maintaining synchronized operations across distributed control architectures.

Moreover, the CI546 supports integration with ABB’s Master software and Advant Open Control Systems, making it suitable for legacy system upgrades and hybrid installations. In addition, its compact form factor and low power consumption allow easy deployment in space-constrained environments. Therefore, it’s widely used in process industries where stable and scalable communication is critical.

Technical Data

Typical Applications

Process Automation Systems

Enables communication between controllers and field devices in chemical, pharmaceutical, and food industries.

Power Generation Facilities
