ABB CI840A Profibus Communication Interface Advanced Control Solutions
The ABB CI840A is a Profibus communication interface designed for industrial automation. Key specs include a data rate up to 12 Mbps, support for up to 125 nodes, and compatibility with PROFIBUS DP and PA protocols. It's typically used in process control systems, manufacturing automation, and building management. Compared to the ABB 200-CICN 200-CIE, which uses Ethernet, the CI840A offers robust Profibus connectivity but lacks Ethernet support. It's ideal for environments requiring high-speed, reliable fieldbus communication.
