Product Overview

The 1769-CRL1 is a communication bus expansion cable designed to connect two separate banks of 1769 Compact I/O modules. This Right-to-Left cable enables systems that exceed the physical capacity of a single DIN rail or require a second I/O bank due to power supply distance ratings. By extending the passive backplane, the 1769-CRL1 ensures high-speed communication between the controller and modules on a secondary rail.

Common Technical Questions

What is the difference between 1769-CRL1 and 1769-CRR1?
The 1769-CRL1 connects the Right side of a bank to the Left side of the next bank. The 1769-CRR1 is a Right-to-Right cable used for specialized rack layouts.

Can multiple 1769-CRL1 cables be chained together?
No. Expansion cables must connect between two 1769 module or power supply bus connectors and cannot be directly linked to each other.
