A switching device switches at least one current phase between responsive current phase input and responsive current phase output, wherein the switching device is suitable for switching electrical current of a power circuit of an electric motor. The switching device further includes a first communication system interface for a first communication system, a second communication system interface for a second communication system, and a selecting unit for selecting whether the switching device is a master or slave in relation to the second communication system.

Switching device and system with switching device

A switching device comprising switching means for switching at least one current phase between responsive current phase input and responsive current phase output, the switching device being suitable for switching electrical current of a power circuit of an electric motor, further comprises a first communication system interface for a first communication system, a second communication system interface for a second communication system, and a selecting unit adapted to select whether the switching device is a master or slave in relation to said second communication system.

Switching device and a system comprising the same

It is normal practice in automation to network individual components of an installation via bus lines, with this network carrying out a multiplicity of communication and supply tasks during operation. In at least one embodiment, a system interface, as well as an installation which uses this interface, are disclosed with the operational reliability of the installation being improved. In at least one embodiment, a system interface is proposed for connection of a bus line to an actuator assembly in a control system with a K connection for connection of a communication channel and with a K-U connection for connection of a communication voltage supply channel, and an A-U connection for connection of an actuator voltage supply channel.

System interface and installation with the system interface

The invention relates to a regulating device () for a motor, comprising a housing () which can be associated with said motor and in which a control unit () and an actuator () are arranged. Due to heat-related reasons, said device can only be used in an encapsulated manner, for example close to a motor. In order to solve this problem, the actuator () comprises an electromagnetic switching element () and the control signal () for the same is designed as a timing signal which is measured&#x2014;taking into consideration at least one heat source inside or optionally outside the housing ()&#x2014;in such a way that the operating temperature of the electromagnetic switching element () is below an upper authorised limiting value.

Regulating device for a motor

A module for making an actuator or sensor of any design accessible to a bus. The module is provided with a device connection to which the device can be directly coupled. The module has electronics on a printed-circuit board, which is connected to the contact pins for contacting a bus line.
