Technical Parameters & Selection Guide

Selection Criteria: Choose the CI853K01 when your application requires simultaneous communication with two independent serial devices, or when integrating Modbus RTU equipment into ABB AC 800M control architectures. For single-port requirements, consider the CI851 model. For PROFIBUS connectivity, evaluate the CI801 alternative. Verify that your serial devices operate within the 300-38,400 bps range and use standard RS232-C signal levels.

Frequently Asked Questions

How do I connect RS232 devices with different baud rate requirements?
Each of the two RS232-C ports can be configured independently with different baud rates, parity settings, and protocols. Port 1 might operate at 9600 bps for a legacy analyzer while Port 2 runs at 38,400 bps for a modern barcode scanner—all configured through Control Builder M software.

What is the maximum cable distance for reliable RS232 communication?
Standard RS232-C specifications support 15 meters at maximum baud rate (38.4kbps). For longer distances up to 50 meters, reduce baud rate to 9600 bps or lower and use high-quality shielded twisted-pair cable. For distances exceeding 50 meters, consider RS485 converters or fiber optic extenders.

Can this module interface with non-ABB control systems?
While designed for ABB AC 800M controllers, the CI853K01's Modbus RTU support enables integration with any Modbus-compatible master device from Siemens, Schneider Electric, Rockwell Automation, or other vendors. Consult our integration team for multi-vendor system architectures.

Does the module require external power supply installation?
No external power needed. The CI853K01 draws all operating power (max 2.5W) directly from the S800 I/O ModuleBus backplane, simplifying installation and reducing panel wiring complexity. Ensure your S800 power supply has adequate capacity for additional modules.

What happens during module replacement in a live system?
The hot-swap design allows module removal and installation while the system remains operational. Communication on the affected ports will pause during the 10-15 second replacement window, then automatically resume once the new module initializes. No controller restart or configuration download required.

Is special training required for module configuration?
Basic familiarity with ABB Control Builder M software is sufficient. The intuitive configuration interface uses dropdown menus for baud rate, parity, and protocol selection. Comprehensive video tutorials and step-by-step guides are available in our knowledge base. On-site commissioning support available for complex deployments.
