Assignee:

Rockwell Automation Technologies, Inc. - Mayfield Heights OH

International Classification:

G01R 19/00

US Classification:

702 64, 702 60, 702 61, 702 62, 324110, 324 74

Abstract:

A system operable to detect voltages within an electrical device and provide an output based on the voltages detected by the system. The electrical device may include an isolation switch adapted to selectively isolate the electrical device from an electrical bus. The system may be operable to detect voltage data in the electrical bus and the electrical device downstream of the isolation switch. The system may provide an indication that voltage is detected in the electrical bus, but that no hazardous voltages are detected within the electrical device downstream of the isolation switch. The system may be adapted to produce a plurality of outputs based on the voltage data detected on the electrical bus and in the electrical device downstream of the isolation switch.

Assignee:

Rockwell Automation Technologies, Inc. - Mayfield Heights OH

International Classification:

G06F 1/00
H02J 7/00

US Classification:

713340, 713300, 713330, 307 64, 307 65, 3406932

Abstract:

A network is configured to apply power and data signals to networked devices for operation of the devices. A backup power supply module is coupled to the source of network power and to a secondary power source. The secondary power source may have an adjustable voltage level or a level fixed with relation to the network power voltage level. In the event of a loss or insufficiency of network power, power from the secondary source is automatically applied to the connected device or devices. The device may be programmed for certain failure modes and the secondary power source provides the power needed for operation in the event of loss of network power.

US Classification:

713340, 713300, 713330, 307 65, 307 64, 3406932

Abstract:

A technique is provided for applying secondary or backup power to a networked device in the event of a loss or malfunction of network power. In a control and monitoring network. Various devices may receive both power and data signals from a network cable. In the event of loss of network power, or the reduction in network power, the devices can automatically and without interruptions seek power from the secondary power source.

International Classification:

H01R 13/64

US Classification:

439248, 4399241

Abstract:

A connector arrangement for packaged electrical systems, such as motor control centers includes a component connector assembly mounted to component supports for providing network signals and control power to components on the support. A mating prewired connector assembly in the enclosure is forced to mate with the component connector assembly when the component support is fully engaged within the enclosure. Thereafter, the component support may be partially withdrawn from the enclosure to disconnect main power from the component support, while leaving network connections and control power connections by virtue of the mated connectors. The connectors engage by non-sliding contact both when fully engaged and when the components are partially withdrawn from the enclosure.

International Classification:

H05K 5/00

US Classification:

361752, 361800, 361790

Abstract:

A packaged electrical system includes an enclosure and a main interior volume for component supports. The component supports may support electrical, electronic, power electronic and similar components, as well as switchgear and the like. A main power wireway is provided adjacent to the main interior volume of the enclosure for accommodating three phase power conductors. A network and control power wireway is formed separately from the main power wireway. The network and control power wireway may be formed toward the rear of the main interior volume, and may accommodate plug-in connections between component supports and network conductors and control power conductors. The network and control power wireway is thus accessible through a separate door from the main power wireway.

Abstract:

A motor control center comprises a plurality of bays in which switchgear components, circuit protective components, automation components and power electronic components are disposed for driving motors and other loads. Network optical conductors are routed through one or more wireways adjacent to the bays. Distribution nodes are coupled to the conductors and are interconnected with respective network terminals within the bays. Components within individual bays for which EtherNet and/or Internet connectivity is desired are coupled to the network terminals. The conductors may comprise plastic optical fibers and may be designed to operate in the relatively high voltage environment of the motor control center bays.
