  • Patent number: 9209712
    Abstract: A method for operating an output module having an output circuit by which a voltage resulting in a current is connected to a load connected to an output, wherein a first driver module is operated and activated via a first control input to connect a voltage to the output, a second driver module is operated in parallel with the first driver module and activated via a second control input to also connect a voltage to the output, at a start time a control circuit receives a switching command for switching the voltage to the output, and wherein the control circuit initially starts by reciprocally activating the first and second control inputs respectively for a first time period, and wherein during this reciprocal activation, the first and second driver modules conduct the current for each respective duration of first and second activation periods.

  • Patent number: 9124269
    Abstract: A method for operating an output subassembly in which a first driver module is operated between a power supply connection on the output subassembly, and an output and is actuated via a first control input to connect the voltage to the output, wherein a second driver module is operated in parallel with the first driver module and is actuated, via a second control input, to connect a voltage to an output, where at an initial time a control circuit receives a command to switch the voltage to the output and the control circuit thereupon initially actuates the second control input for a predefined first length of time, so that the second driver module is operated with current limitation up to a maximum current and, after a predefined second length of time, measured from the initial time, the control circuit actuates the first control input when the command is in effect.

  • Patent number: 8698353
    Abstract: A method for safely detecting in two redundantly-configured output modules a possible wire break of a load, wherein during a switch-off test of a first module, a current test is performed in the respective other module and a binary test is performed in the switched-off module. The binary test determines whether the voltage switched off through the respective other module is also reaching the module with the binary tests over corresponding connection paths.

  • Patent number: 8587323
    Abstract: A output assembly and method for diagnosing an electrical connection for reliably identifying a possible wire break to a load in redundantly connected output assemblies in which a control device for operating a switching device is configured such that the control device subjects the measured value to a test criterion, wherein satisfaction of the test criterion initially noted in the output assembly as a diagnosis fault, and the test criterion is applied cyclically within a time period comprising a waiting time, and wherein another output assembly performs a switch-off test during this time, thus allowing a statement to be made as to whether a wire break is present.

  • Publication number: 20120139362
    Abstract: A fail-safe switching module having a first switching device and a second switching device, the first and second switching devices being configured to switch a load by a switching-on device, a first temperature sensor being arranged on the first switching device and a second temperature sensor being arranged on the second switching device. The first switching device is arranged in series with first and second switching-off devices, and the second switching device is arranged in series with third and fourth switching-off devices. The first switching-off device and the third switching-off device are configured to react to the first temperature sensor. The second and fourth switching-off devices are configured to react to the second temperature sensor to switch off the first and second switching devices in the event of an overtemperature of the first switching device or the second switching device.
