Product Overview

The CI853K01, cataloged under order number 3BSE018103R1, is a specialized dual-channel communication interface designed for the ABB AC 800M controller series. Unlike standard fieldbus modules, the CI853K01 provides two independent RS-232C ports, enabling the controller to interface with a variety of peripheral devices and legacy systems via serial protocols. This module is essential for applications requiring point-to-point communication, such as connecting to modems, printers, third-party PLCs, or specialized analytical instrumentation. By offloading serial processing from the main CPU, the CI853K01 ensures that high-speed control logic remains deterministic while maintaining versatile connectivity across the plant floor.

Industrial Connectivity and Operational Applications

The flexibility of the RS-232 interface makes the CI853K01 a vital component for integrating non-native hardware into the ABB System 800xA environment.

• Third-Party Device Integration: Seamlessly connects AC 800M controllers to weighing scales, barcode readers, and laboratory instruments via Modbus RTU.

• Remote Telemetry: Interfaces with radio modems or GSM units for distributed data acquisition in water treatment or pipeline monitoring.

• Legacy Infrastructure Bridging: Allows modern DCS platforms to exchange data with older PLC systems using COMLI or 3964R protocols.

• Diagnostic Serial Logging: Facilitates the connection of local serial printers or terminal servers for real-time event logging and system diagnostics.

• Redundant Communication Paths: Can be utilized to create secondary data paths for critical monitoring sensors that do not support standard Ethernet or Fieldbus interfaces.
