Abstract: A module carrier for use in a potentially explosive atmosphere, in particular in a potentially explosive atmosphere in the form of gas or dust, including a housing for receiving at least one module with a pushbutton, wherein the at least one module can be switched to live via the pushbutton, wherein the module carrier further includes a locking cap, wherein the locking cap has a device for actuating the pushbutton and wherein, in the unactuated state, the pushbutton is switched to not live and the pushbutton is actuatable by locking the locking cap using the actuating device.

Abstract: An I/O system component for a switch and control cabinet for components and/or functional units of an I/O network, including: a housing with a front, a top, a bottom, at least one side face, and a sensor window; at least one ultrasonic sensor for detecting at least one physical quantity, the at least one ultrasonic sensor being arranged behind the sensor window; and at least one printed circuit board, the at least one ultrasonic sensor being connected to the printed circuit board so as to carry data.

Abstract: An integrated circuit for controlling an alternator circuit in an alternator regulator charging system. The integrated circuit includes a first circuit for performing core regulation functions; a second circuit having a mask selectable operation circuit that allows the integrated circuit to select an operational mode thereof, the mode being selectable from one of a stand-alone mode, a remote controlled mode wherein the first circuit is controlled by an external circuit, and a combination of the stand-alone mode and the remote controlled mode; and a third circuit having an output driver circuit for controlling a field winding of the alternator circuit.
