Product Details

The CI810B 3BSE020520R1 is AF100 fieldbus communication interface module for ABB AC800M and 800xA DCS control system.

This module connects to ModuleBus backplane bus, serves as main interface for AF100 remote I/O network. It supports up to 64 AF100 remote I/O nodes, realizes bidirectional real‑time data transmission between DCS controller and distributed field I/O units. Field analog and digital signals are uploaded to controller, while control instructions are issued down to field stations.

Hot‑swap function supports online module replacement without DCS shutdown. Front‑panel LED indicators show power, bus link and fault status for quick field diagnosis. Built‑in bus diagnosis function detects bus failure, remote station dropout and communication error, and feeds alarm information back to DCS controller.

Compact rack‑mount structure saves cabinet space. Conformal coated circuit board improves anti‑interference performance, adapts to complex electromagnetic environment of industrial workshops.

Widely used in maintenance and renovation projects of legacy AF100 DCS system in power, chemical and papermaking industries.

It is important spare hardware for AF100 fieldbus loop debugging and defective CI810B module replacement.
