Description
ABB CI871AK01 3BSE092693R1
This is a high-performance communication interface module designed specifically for industrial automation systems. It is primarily used in ABB’s AC 800M and 800xA distributed control systems (DCS). As a key communication component, it enables efficient and reliable data exchange between controllers and field devices.

Core functions and types
Function Type: This module primarily functions as a PROFIBUS-DP slave communication interface, connecting an AC800M/800xA controller to a PROFIBUS-DP fieldbus network.
Main Function: Serves as a communication bridge between the controller and lower-level intelligent devices (such as inverters, remote I/O modules, and instruments), enabling centralized monitoring and control of these devices.
Protocol Support: Supports PROFIBUS-DP V0 and DP-V1 protocols, with automatic baud rate detection and a maximum communication rate of 12 Mbps.
Key Product Features
Efficient and Stable Communication: Ensures fast and stable data transmission in complex industrial environments.
Modular and Easy Integration: Adopts a standard modular design and can be directly plugged into an 800xA-specific rack or mounted via DIN rail, facilitating system expansion, maintenance, and upgrades.
Industrial-Grade Reliability: Features excellent electromagnetic interference immunity and a wide operating temperature range (-25°C to +70°C), making it suitable for harsh industrial environments.
Easy Configuration: Configurable PROFIBUS network addresses are simple via DIP switches.
Status Visualization: LED indicators display module operating and communication status in real time, facilitating troubleshooting and maintenance.
Plug-and-Play: Strong compatibility allows for rapid deployment within existing ABB control systems, reducing downtime
