Abstract:
1. 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, the method comprising: operating and activating a first driver module arranged between a supply-voltage terminal of the output module and the output, via a first control input to connect a voltage to the output; operating and activating, a second driver module, arranged between the supply-voltage terminal and the output, in parallel with the first driver module via a second control input to connect the voltage to the output; receiving, by a control circuit, a switching command for switching the voltage to the output at a start time; and initially reciprocally activating, by the control circuit, the first and second control inputs, respectively; wherein the reciprocal activation is performed for a duration of a first time period, and during this reciprocal activation, the first driver module conducts the current for each duration of a first activation period, and the second driver module conducts the current for the duration of a second activation period; and wherein the current is measured via a current measuring instrument, and the reciprocal activation of the first and second driver modules is operated during said reciprocally activating step irrespective of the first time period until the measured current is below a predetermined value.
