ABB CI854A (3BSE030221R1) is a compact, rack-mountable dual-channel PROFIBUS DP-V1 master module in ABB’s CI800 series, designed to extend connectivity for AC 800M controllers and 800xA DCS systems. It provides two 9-pin D-sub female connectors for independent Profibus DP networks, supporting cyclic/acyclic data exchange and diagnostics. With baud rates from 9.6 kbps to 12 Mbps and automatic detection, it simplifies configuration. The module supports line redundancy (dual communication lines) and master redundancy (with redundant CPUs/CEXbus), eliminating single points of failure. Hot-swappable and certified CE/UL, it operates reliably in harsh environments with wide temperature tolerance.
