Product Description
ABB CI840A Communication Interface Module
The ABB CI840A is a robust PROFIBUS DP-V1 communication interface module designed for the AC 800M controller system. It functions as a master on the PROFIBUS DP network, enabling seamless integration and control of field devices. The CI840A supports full redundancy, allowing for a high-availability setup with a second module to ensure continuous operation. It connects to the controller via the CEX-Bus and features status indicators for diagnostics and two 9-pin D-sub connectors for the PROFIBUS line, providing reliable and high-speed data exchange for demanding industrial automation applications.
