Communication Module ABB CI853 Automation Systems

Description

The ABB CI853 Communication Module is engineered to provide flexible and secure serial communication for distributed control systems. It supports both COMLI (ABB’s proprietary protocol for asynchronous master/slave communication) and MODBUS RTU, which is widely adopted across industrial devices due to its simplicity and reliability. Moreover, the CI853 allows extended cable lengths when combined with fiber optic converters, making it suitable for large-scale installations. In addition, the module supports hot-swap functionality, reducing downtime during maintenance and upgrades.
