Allen-Bradley 1769-CRL1 Compact I/O Right-to-Left Expansion Cable

Product Description

The 1769-CRL1 (1769-CRL1) is a specialized 1-foot (30.5 cm) bus expansion cable engineered for Allen-Bradley CompactLogix and MicroLogix 1500 control systems. This "Right-to-Left" cable is the critical hardware link required to connect two separate banks of 1769 Compact I/O modules, effectively extending the passive backplane across different DIN rails within a single control cabinet.

The 1769-CRL1 (1769-CRL1) is typically deployed when a system exceeds the physical length of a single mounting rail or when the controller’s power supply distance rating requires the creation of a secondary I/O bank. It features heavy-duty multi-pin connectors with integrated locking latches to ensure high-speed signal integrity and vibration-resistant connectivity. As a passive component, it facilitates seamless communication between the CPU and expansion modules without consuming additional backplane current.
