Bus Expansion Cables | Allen-Bradley 1769-CRL1
The Allen-Bradley 1769-CRL1 is a 1 ft (305 mm) right-to-left bus expansion cable for the CompactLogix and Compact I/O platform architectures. It enables high-speed communication and power transfer between two adjacent I/O banks, extending control systems when chassis slot capacity limits a single bank.
Technical Specifications
| Parameter | Specification |

System Integration and Bank Layout
The 1769-CRL1 module-to-module cable routes signals from the right end of one Compact I/O bank to the left end of the next bank. This connection permits multi-bank layouts within the same enclosure while preserving backplane signal integrity and maintaining standard CompactLogix addressing logic.
Cable Handling and Installation Constraints
Designed with heavy-duty molded end connectors, the cable snaps securely into the expansion bus interfaces of 1769 I/O end caps or expansion power supplies. Installers must respect minimum bend radii during cable routing to prevent internal conductor strain or signal attenuation across the multi-bank arrangement.
Frequently Asked Questions
Q: What is the primary function of the 1769-CRL1 expansion cable? A: The 1769-CRL1 connects the right side of a Compact I/O bank to the left side of an adjacent Compact I/O bank, allowing system expansion across multiple sub-racks.
Q: How does the 1769-CRL1 differ from the 1769-CRR1 cable? A: The 1769-CRL1 provides right-to-left bank expansion, whereas the 1769-CRR1 is intended for right-to-right bank extension configurations.
