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.

Output module and method for operating the output module

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.

Output subassembly and method of operating the output subassembly

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.

Method for operating a redundant system and system therefor

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.
