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

An input circuit (') provided with a time delay element (), which circuit is capable of being tested by a controlled high level or low level connection, and a method for the operation thereof. The delay time of the time-delay element can be modified during operation of the input circuit. In particular, the elapsed delay time is read out prior to the testing of the input circuit and is restored again after testing, so that the test does not increase the effective input delay time for the process signals. In addition or as an alternative, the delay time is set to a minimum value prior to the test to enable rapid testing of the input circuit independent of the set delay time.
