Abstract: The invention relates to a safety-related switching device (10) which is equipped with an electromagnetic coil (12), a control unit (20) and a first switching means (22). The first switching means (22) is designed to activate and deactivate the electromagnetic coil (12). Moreover, the first switching means (22) is designed to receive a coil control signal (24), a monitoring signal (32) and a first higher-level control signal (26). The safety-related switching device (10) also has a receiver unit (40) for receiving an external control signal (29). The receiver unit (40) is designed to generate the first higher-level control signal (26) and a second higher-level control signal (28) from the external control signal (29). The control unit (20) is designed to receive the second higher-level control signal (28).

Abstract: An embodiment relates to a control device for an electric load and to a corresponding method for operating such a control device, the control device being designed as an insert module for inserting into an insert shaft. Depending on the design, the insert shaft is provided with or without a storing device for storing configuration data and/or operating parameters of the control device or the electric load. The control device includes: a) a first device for checking whether a storing device is present or not, b) a second device for implementing the function of reading the parameters and data for operating the control device if a storing device is present, the parameters and data being stored in the storing device, and not carrying out a start-up if a storing device is not present, and c) the function of not carrying out a start-up when a storing device is not present can be deactivated.

Abstract: A plug-in connection system is disclosed which is economical to produce, is compact, is easy to handle and/or which connects to a module in an electrically reliable manner. A plug-in connection device includes locking hooks which are provided includes locking hooks which are provided with unlocking elements. As a result, the locking hooks can be maintained in an unlocked position such that the plug-in connection can be released in a simplified manner. The unlocking elements may project in an essentially non vertical manner over the housing of the connection device or in an extrinsically vertical manner over the housing of the connection device. The total space required for the plug-in connection system is reduced, thereby ensuring that the module is connected in an electrically reliable manner.
