Product Introduction
The Allen Bradley 1769-CRR3 CompactLogix Compact I/O Communication Bus Expansion Cable is designed to extend the internal communication bus between separated Compact I/O module banks within CompactLogix control systems. This cable enables flexible system layouts by allowing multiple groups of 1769 I/O modules to be installed in different sections of a control cabinet while maintaining continuous backplane communication.
The 1769-CRR3 cable features a right-to-right connection orientation, which connects the right expansion port of one Compact I/O bank to the right expansion port of another. This configuration supports system expansion while preserving the integrity of the CompactLogix backplane communication architecture.
Built for industrial environments, the cable operates reliably within standard industrial temperature ranges and supports stable signal transmission between module banks. It plays an important role in expanding CompactLogix systems without affecting controller performance or requiring additional communication hardware.
