The Allen-Bradley 1769-CRL3 Compact I/O cable is used to extend the reach of 1769 bus communication lines, enabling more flexibility for controllers in the DriveLogix 5730 series. It is a right bank-to-left bank expansion cable type and can be used with up to two cables in a 1769 system to support three banks of I/O modules, with each bank requiring its own power supply. The 1769-CRL3 is not a module or a power supply, but rather a cable to connect banks or groups of modules.

The 1769-CRL3 cable measures 3.28 feet in length and has an approximate weight of 350 grams. It has an operating temperature range of 0 to 60 degrees Celsius and a storage temperature range of -40 to 85 degrees Celsius. It is rated for an operating altitude of 6561 feet and a relative humidity range of 5% to 95% non-condensing humidity.
The cable’s operating vibration rating is up to 5 G between a frequency range of 10 to 500 Hertz with amplitude up to 0.030 inches from peak to peak, and its general relay operation is rated for 2 G. It can withstand up to 5 G when DIN-rail-mounted and up to 7.5 G when panel-mounted. Its operating shock rating is 20 G when DIN-rail-mounted and up to 30 G when panel-mounted, and its non-operating shock rating is 30 G when DIN-rail-mounted and up to 40 G when panel-mounted.
The 1769-CRL3 cable is hazardous location-rated, with a Class I, Division 2 rating for use in Group A, B, C, and D locations or non-hazardous locations. The manufacturer recommends that power be removed from components before cable connections are made or broken to prevent electrical arcing and excessive wear for contacts and mating connectors. Integrated circuits or semiconductors could also be damaged by electrostatic discharge if the users touch the bus connector pins or the terminal block, so proper safety guidelines should be followed when handling all 1769 series components.
