Allen-Bradley 1769-CRL3 CompactLogix Right-to-Left Expansion Cable 1m

Product Overview

The 1769-CRL3 is a high-reliability, right-to-left expansion cable designed specifically for the Allen-Bradley CompactLogix and MicroLogix 1500 systems. It facilitates the extension of the 1769 backplane, allowing users to distribute I/O modules across multiple chassis banks. This 1-meter cable is critical for large-scale automation projects where the number of I/O modules exceeds the capacity of a single bank or when physical cabinet constraints require vertical or offset mounting of I/O racks. By utilizing the 1769-CRL3, engineers can maintain high-speed communication integrity across a distributed 1769 backplane architecture.
