Product Details

The CI522A 3BSE018283R1 is a dedicated AF100 Bus Adapter for ABB Advant and AC800M control platforms, acting as critical Redundant Fieldbus Gateway between main controller and distributed S800 I/O subsystems. It converts internal rack bus signals into AF100 fieldbus signals, completing high‑speed data exchange between central control unit and remote I/O stations.

It supports 1.5Mbps high‑speed AF100 bus transmission, adopting daisy‑chain or star network layout, which greatly reduces field cabling workload for scattered I/O points. Dual‑channel hardware design enables redundant fieldbus communication, once one communication link fails, the other channel will take over data transmission automatically, avoiding system communication interruption caused by single‑point cable fault.

Multi‑group LED indicators on front panel show module running status, bus activity and link fault information. Built‑in bus diagnostic circuit can capture communication timeout, signal attenuation and loop short‑circuit faults, and upload alarm information to DCS host through backplane bus. Maintenance technicians can quickly locate fieldbus‑related abnormal points during routine inspection.

Standard rack‑slot mechanical structure, it can be inserted into Advant Master and AC800M controller cabinet slots directly. Widely deployed in thermal power, pulp‑paper and petrochemical process industries. It is essential communication hardware for S800 I/O station expansion, fieldbus network reconstruction and defective interface module replacement for legacy ABB DCS automation systems.
