Allen-Bradley 1769-CRL3 Compact I Expansion Cable

Allen-Bradley 1769-CRL3 Compact I Expansion Cable is a 1-meter right-bank-to-left-bank expansion cable for 1769 Compact I/O in Rockwell Automation’s CompactLogix systems. This 3.28 ft cable provides the physical link between the right I/O expansion bank and the left bank, enabling additional 1769 Compact I/O modules to be added to the same network. The assembly weighs approximately 350 g (0.77 lb) and is specified at a 1 m (3.28 ft) length. Designed specifically for expansion within the Compact I/O bus, the 1769-CRL3 is one of the standard cables used to extend the bus between banks for 1769 modules. It is compatible with 1769 Compact I/O modules and is identified in Rockwell documentation as the right-bank-to-left-bank expansion cable of 1 m length. Typical applications include adding digital, analog, or specialty I/O modules to an existing CompactLogix or Compact I/O installation without altering the controller or overall topology.
