Allen-Bradley 1769-CRL3 CompactLogix Bus Expansion Cable
The Allen-Bradley 1769-CRL3 is a 3.28 ft (1 m) right-bank to left-bank bus expansion cable designed for CompactLogix, DriveLogix 5730, and Compact I/O system architectures. It passes bus communication lines and power signals across multi-bank configurations when an installation requires expanding beyond a single chassis or power supply limit.

Multi-Bank System Expansion and Topologies
The 1769-CRL3 routes control signal tracks from the right end of one Compact I/O bank to the left end of an adjacent bank. A 1769 system architecture permits up to two bus expansion cables in series, allowing control integration across a maximum of three distinct I/O banks, with each bank utilizing its own expansion power supply.
Mechanical Integration and Installation Limits
The 1 m physical length enables both horizontal side-by-side mounting and vertical multi-tier enclosure arrangements. Mechanical installations must adhere to the specified shock and vibration thresholds based on panel-mounting or DIN-rail configuration to preserve connector seating and signal integrity.
Frequently Asked Questions
Q: How many 1769-CRL3 cables can be used within a single 1769 Compact I/O system? A: A 1769 system architecture supports a maximum of two expansion cables, enabling a total system layout of up to three module banks.
Q: Can the 1769-CRL3 cable be used for vertical mounting configurations? A: Yes, its 3.28 ft length provides sufficient flex and reach to link I/O banks arranged horizontally side-by-side or stacked vertically across DIN rails.
