Product Introduction
The ABB CI810B, part number 3BSE020520R1, is an AF100 fieldbus communication interface module for ABB AC800M and 800xA distributed control systems. It acts as the gateway between AC800M controller and AF100 fieldbus I/O stations, transferring real-time process values, control commands and diagnostic data between the rack controller and remote S800 I/O units. Built with industrial-grade PCB and robust EMC protection, the module maintains steady data transmission in harsh industrial environments with temperature swings, dust, vibration and strong electromagnetic interference. Widely deployed in power, petrochemical, pulp & paper, metallurgy and water treatment industries. It serves as a critical spare part for AC800M cabinet maintenance, AF100 communication module replacement and DCS system retrofit.
Content Details
Brand: ABB Model: CI810B Part No: 3BSE020520R1 Product Type: AF100 Fieldbus Communication Interface Module Applicable System: ABB AC800M / 800xA DCS Bus Type: AF100 Fieldbus The ABB CI810B 3BSE020520R1 is a plug-in module mounted on matching baseplate inside AC800M control rack. It links the controller CEX bus to AF100 fieldbus network. It collects analog and digital signals from distributed S800 remote I/O stations and delivers control instructions from DCS controller to field actuators. It handles cyclic real-time data for continuous process regulation and non-cyclic access for parameter configuration and fault diagnosis. This module supports hot-swap operation. Technicians can replace the module without powering down the whole control rack, minimizing production downtime during maintenance. Each unit passes full functional testing and aging screening before delivery to ensure reliable 24/7 continuous operation. Built-in signal isolation and surge protection circuits block voltage spikes and ground loop noise, preventing damage to the main controller from field circuit faults. It can be configured and diagnosed via ABB Control Builder engineering software. LED indicators on the front panel indicate power status, fieldbus link activity and fault alarms, helping maintenance personnel quickly identify bus communication breakdowns and shorten equipment outage time. Multiple S800 I/O stations can be connected on AF100 bus to expand the DCS input and output capacity. Typical application scenarios include thermal power DCS control, chemical continuous process monitoring, paper mill automation, metallurgical production line control and municipal wastewater treatment. When the original AF100 communication interface fails, CI810B 3BSE020520R1 can be directly replaced to restore AF100 fieldbus communication of the entire AC800M DCS system. This module complies with CE, UL and IEC industrial safety and EMC standards, IP20 protection rating. Compact modular rack design and high-quality electronic components support long-term stable operation. Whether you build spare inventory for equipment overhaul or buy components for DCS upgrade projects, the ABB CI810B AF100 communication module delivers dependable fieldbus connectivity for your AC800M automation system.
