  • Patent number: 6795320
    Abstract: A technique for supplying power and data signals to panel-mounted components includes distribution of power and data conductors in a trunk wireway and further distribution to component locations via drop cable assemblies disposed in drop wireways. The drop cable assemblies and trunk cable assemblies may include identical cable. The cables have a plurality of parallel conductors in an insulated jacket. Connectors are mounted on the drop cable assemblies for receiving plug-in component cable assemblies routed to individual components mounted within component panels or bays. The components are thus electrically coupled in parallel with one another and may receive both power and data signals via the drop and trunk cable assemblies coupled to a network. Individual components may be independent installed and removed for servicing with interrupting service to upstream or downstream components in the system.
    Type: Grant

    Date of Patent: September 21, 2004
    Assignee: Rockwell Automation Technologies, Inc.
