ABB CI858K01 3BSE018135R1 PROFIBUS‑DP Communication Interface Module

The ABB CI858K01 3BSE018135R1 is a high‑performance PROFIBUS‑DP master communication module developed for ABB AC 800M DCS control systems. It realizes high‑speed cyclic data exchange between the controller and PROFIBUS‑DP slave devices, connecting variable‑frequency drives, remote I/O modules and intelligent field instruments for process‑automation control loops.

This S800 I/O rack‑mount unit supports hot‑swap function and comprehensive bus diagnostic capabilities, adapting to harsh industrial field electromagnetic environments. Original production has been discontinued. It is widely used as aftermarket spare parts for power, chemical and pulp‑plant DCS cabinet maintenance and fieldbus network retrofitting projects.
