The Allen-Bradley 1769-CRL3 is a high-quality bus expansion cable designed for the CompactLogix™ and MicroLogix™ 1500 systems. This 1-meter (3.28 ft) cable allows for the physical separation of I/O modules into two distinct rows or "banks" within an enclosure. Specifically, the"CRL" (Left-to-Left)configuration is used to connect the left side of one 1769 expansion bank to the left side of another, providing maximum flexibility for cabinet layout and high-density I/O configurations.
Compatibility:All 1769 Compact I/O modules and controllers
Shipping Weight:Approx. 0.6 kg (1.3 lbs)
Key Features
Multi-Bank Expansion:Enables the controller to manage I/O modules that are not physically snapped together in a single horizontal row, essential for fitting large systems into standard electrical panels.
Rugged Industrial Shielding:The cable is heavily shielded to protect the high-speed backplane data from electromagnetic interference (EMI) and radio frequency interference (RFI) common in industrial environments.
Positive Locking Connectors:Features secure mechanical latches that prevent the expansion cable from vibrating loose, ensuring continuous system uptime.
Left-to-Left Orientation:Designed specifically for layouts where the bus must be "folded" back, connecting the left end-cap position of one row to the left starting position of the next.
Marine Rated:Certified for use in maritime and offshore applications, indicating high resistance to vibration and environmental stress.
