PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-C9 SLC 500 Rack Interconnect Cable links modular chassis and controllers within an enclosure. This ribbon cable measures 36 inches or 3 feet in total length. It joins 1746-A4, 1746-A7, 1746-A10, or 1746-A13 chassis in any combination. Connectors feature rigid shrink wrap to provide strain relief during installation. The flexible cable body simplifies routing between adjacent chassis units.
This interconnect cable supports 110 mA of backplane current at 5 Volts DC. It also supports 85 mA of backplane current at 24 Volts DC. Engineers can connect chassis spaced between 6 and 36 inches apart inside enclosures. The assembly occupies 1 backplane slot and weighs approximately 0.06 pounds. Maintain at least 4 inches of clearance around the connected chassis for proper heat dissipation.
