Product Details

The CI801 3BSE022366R1 is compact Profibus‑DP Slave Interface Module for ABB AC800M DCS system, it is a practical AC800M Fieldbus Comms Unit for cross‑system fieldbus interconnection.

This module operates as Profibus‑DP slave station. It connects to external Profibus‑DP master controller via 9‑pin D‑Sub bus port, and exchanges internal process data with AC800M CPU through CEX‑Bus backplane bus. It supports high baud rate up to 12 Mbit/s, and handles large‑volume input and output cyclic data. Hot‑swap function allows module replacement without powering down the control rack, reducing system maintenance downtime.

LED indicators on front panel show module power status, CEX‑Bus running state and Profibus‑DP bus communication status. Built‑in self‑diagnosis function detects bus short‑circuit, communication interruption and hardware abnormal conditions, and uploads fault alarm information to DCS operator station. Industrial‑grade circuit design satisfies strict EMC anti‑interference requirements of industrial control cabinet.

Adopting standard rack‑slot mechanical structure. Widely used in thermal power, petrochemical, pulp‑paper and metallurgy industries. It is key fieldbus communication hardware for cross‑system interconnection, Profibus‑DP network reconstruction and defective communication module replacement for legacy AC800M automation projects.
