This disclosure provides a field termination assembly (FTA) providing for ease of mounting to a support rail. The FTA provides a lever on a base that cushions against shocks and vibrations during shipment and operation while a housing is mounted on a base secured to a support rail. The base includes a dampener feature which makes it more capable of meeting operation and transportation vibration and shock requirements even for marine applications while still providing high channel density and cable count.

A control-cabinet system has a base module and at least one functional module. The base module has a base housing with a first housing face and a second housing face. The functional module has a functional housing with a housing underside, where a circulation channel is arranged. Air flow may be circulated in the circulation channel, where each base connection element comprises circulation openings which are fluidically connected to the circulation channel. The functional connection element comprises coupling openings fluidically connected to an interior of the functional housing. The coupling openings are coupleable to the circulation openings, in which a fluidic connection exists between the circulation channel and the interior of the functional housing. A fluidically closed circulation circuit comprising the circulation channel and the interior of the functional housing is formed, in which air flow may be circulated.

An electrical apparatus includes an electrical device that generates heat and a fan unit. A case of the electrical device includes a first opening and a second opening. A case of the fan unit includes a third opening and a fourth opening. The case of the electrical device and the case of the fan unit are configured such that a space sandwiched between a recess of the case of the electrical device and the support rail and a space sandwiched between a recess of the case of the fan unit and the support rail constitute an air flow path.

An electrical connection enclosure (100) is supplied with electrical power by power supply cables (102) and supply at least one electrical load (104). The enclosure comprises a power supply column (106) and at least one connection column (110). Each connection column comprises at least one monitoring-and-control unit (138) connected to an electrical load, electrically protected by a protection unit (140) and configured to allow the connection and potentially the driving and/or the surveillance of an electrical load. The electrical enclosure is controlled by an industrial computer (130). Each connection column comprises a communication module (134) which centralizes operating information originating from the monitoring-and-control units of that connection column, transmits this operating information to the industrial computer, receives commands originating from the industrial computer and transmits these commands to the monitoring-and-control units of that connection column. At least one communication module comprises a power supply board delivering at least one auxiliary voltage to each connection column

Various embodiments relate to a method, controller, and machine-readable storage medium for verifying controlled devices attached to the controller including one or more of the following: selecting, using a system model that models a system of devices comprising the controlled devices attached to the controller, a grouping of the system of devices to be tested; conducting a test of the grouping to produce a test result for the grouping, wherein conducting the test comprises transmitting a communication to at least one device associated with the grouping; choosing a graphical representation of a portion of the system model from a plurality of graphical representations based on the graphical representation including a representation of the grouping; and displaying, on a user interface, the graphical representation and an indication of the test result.

Controllers that control a building's state functions can be controlled by a master controller that the controllers choose themselves. The master controller communicates with the controllers and sensors to determine when a building state should change. When the building state should change, the master controller or another controller determines the device or devices that need to modify state values of the building, and send messages to the devices so that they can change building state. If the master controller has a fault, the working controllers can choose another master controller. When a sensor indicates that a building state needs to be changed the master controller determines which device should change state, then tells the controller that is attached to the device.

The present invention relates to a modular component assembly system comprising a supporting profiled rail (200) and at least one bridging module (300) for electrically connecting at least one functional component, wherein the bridging module (300) comprises a modular locking means (301) for locking the bridging module (300) onto the supporting profiled rail (200).

A modular assembly of a module for a Logic Controller, including a container and a cartridge. The cartridge has a first electrical interface part and an electronic circuit arranged to provide a predetermined electronic function. The container has a housing, a backplane connector, a terminal connector and a receptacle extending inside the housing and adapted to receive the cartridge. The receptacle includes a second electrical interface part adapted to connect with the first electrical interface part. The cartridge and the receptacle are arranged to electrically connect the first and second electrical interface parts to establish an electrical interface when the cartridge is removably inserted in the receptacle of the container. The housing of the container defines the mechanical form factor of the module, while the cartridge determines the electronic functionality of the module. Accordingly, multiple containers having different form factors may accommodate the same cartridge.

The present invention provides a connection structure and an apparatus unit that can avoid damage to connectors when the connectors are caused to be connected to each other. Through rotation of a first option unit towards an inverter body, the connection structure connects a first connector disposed in the inverter body and a second connector disposed in the first option unit, and the first connector and the second connector are floating connectors.

An electronic device includes a plug-in module including a printed substrate on which an electronic circuit is mounted, and a baseplate to which the plug-in module is detachably connected, wherein a system side and a field side are connected with each other, and a predetermined option function is included in the plug-in module.
