摘要:
Service devices are used in the field of automation and normally form interfaces between programmable logic controllers (PLC) and the installations or installation components to be controlled. Service devices such as these generally have a multiplicity of electrical interfaces for additional modules, with the additional modules being connected via control lines to the PLC, to further service devices or to installation components. An electrical additional module for a service device, a combination of the additional module with the service device, and an additional module set having various additional modules which allow easier fitting and removal of the additional modules in the service device are disclosed. In at least one embodiment, an electrical additional module is proposed, having an appliance interface for fitting the additional module to a service device, with the service device having a stepped holding geometry with at least two steps on each of which a contact device is arranged for holding an electrical opposing contact device, with the appliance interface having step sections which are designed to be complementary to the at least two steps and on which in each case one of the electrical opposing contact device is arranged in order to make contact with the associated contact device, and with the at least two step sections being rigidly connected to one another when the additional module is not fitted.

A heat exchanger and a method of manufacturing a heat exchanger are described and shown. In some embodiments, the heat exchanger has a brazed core with flat metal tubes and flat metal tube ends received in corresponding openings defined in a collecting tank, and has a plurality of adhesive connections each with an annular space around a flat tube end and defined at least in part by the collecting tank, an addition-crosslinking silicone adhesive located within the annular space, and a mounting plate at least partially closing each annular space. In some embodiments, a method for producing an adhesive connection for flat metal tube ends in corresponding openings of a collecting tank of a heat exchanger is provided, and includes pushing an addition-crosslinking type silicone adhesive into annular spaces located between each flat tube end and a corresponding opening of the collecting tank with a mounting plate, at least partially filling the annular spaces by pushing the silicone adhesive into the annular spaces with the mounting plate, and closing the annular spaces with the mounting plate.

A module includes a mounting plate and a housing, which can be swiveled onto the latter. The housing includes a housing base and a housing cover joined together with the housing base in an interlocked manner. Inserted between the housing base and the housing cover is a seal, which becomes fully functional when the housing is screwed to the mounting plate.

A control module with connection devices for connection to connection terminals of a load feeder is disclosed. The control module may include a device interface for at least one connection, the interface being independent of the bus system, with a shut-off element able to be connected to the at least one connection device and with the load feeder able to be shut off by way of the shut-off element independently of the bus system. The control module may be plugged into connection terminals of the load feeder.

There is described a method and a system for monitoring a protective apparatus, which is connected upstream of a switching device and is connected to the switching device via at least one main current path. The wiring complexity for monitoring of the protective apparatus is minimized. This is achieved by virtue of the fact that the sate of the protective apparatus is determined by a tap of the at least one main current path at or in the switching device by means of an evaluation unit. As a result of this direct evaluation of the switching state of the protective organ on the switching device, the wiring which until now has been required for an addition auxiliary switch on the protective device is dispensed with a possible fault source also being minimized along with the wiring complexity. For this purpose, the proposed solution is also independent of the physical design (branch-oriented or row-oriented, distance between the devices) in a switchgear cabinet.

A control module with connection devices for connection to connection terminals of a load feeder is disclosed, wherein the load feeder with the control module is connected to a bus system. In at least one embodiment, the control module includes a device interface for at least one connection, interface being independent of the bus system, with a shut-off element able to be connected to the at least one connection device and with the load feeder able to be shut off by way of the shut-off element independently of the bus system. At least one embodiment of the present invention further relates to a load feeder for turning a load on and off and/or for monitoring thereof, including first connection devices for connecting the load feeder to a bus system, second connection devices for connecting the load and a control module, wherein the control module is plugged into connection terminals of the load feeder for connecting to the load feeder and wherein the control module includes a device interface for at least one connection device, the interface being independent of the bus system, with a shut-off element able to be connected to the at least one connection device and with the load feeder able to be shut off by way of the shut-off element independently of the bus system.

At least one embodiment of a plunger has, when viewed in a longitudinal direction, a central region and two outer regions adjoining the central region. The outer regions are injection-moulded from a non-magnetizable material. In the central region, a magnetizable material is integrated in the plunger. In at least one embodiment, an injection-mouldable material is used as the magnetizable material, and the plunger including the magnetizable material is manufactured by way of a two-component injection-moulding process. A defined magnetization is impressed on a section of the central region once the magnetizable material has been integrated in the plunger.

A module for connecting actuators and/or sensors having a housing that can be mounted on a base and a contact unit with contact pins. To enable the connection of a round cable, at the same time maintaining a simple design and easy contacting, the proposed base has an accommodating element projecting beyond the housing with an accommodating aperture for a plug coupling of a round cable connection that can be brought into contact with a connector, with the connector having contact elements that can engage with the contact pins.
