Abstract
A circuit is provided that has a safety-related digital input and an input circuit downstream of the safety-related digital input. The input circuit has a comparator circuit connected to the safety-related digital input and arranged to output a first value when a voltage applied to the comparator circuit is in a first range and to output a second value when the voltage applied to the comparator circuit is in a second range. The input circuit is also arranged to close a switch connected to the safety-related digital input for discharging capacitive elements in preparation for a test and to evaluate the voltage applied to the comparator circuit during the test.
