Circuit arrangement for electronic system for time-delayed output of switching signal has control unit per timer element for determining specified time delay, processing relevant time delay

摘要

The arrangement has a first timer element for converting an input signal into a first delayed output signal, a second redundant timer element for converting the input signal into a second delayed output signal, a common control element for the input signal and timer elements and a control unit per timer element for determining the delay specified by the control element and processing the relevant time delay for outputting the switching signal. The arrangement has a first timer element (9) for converting an input signal (22) into a first time-delayed output signal (23), a second redundant timer element (10) for converting the input signal into a second time-delayed output signal (24), a common control element (8) for the input signal and both timer elements and a control unit (2,3) per timer element for determining the time delay specified by the control element and for processing the relevant time delay for outputting the switching signal (20,21). AN Independent claim is also included for the following: a method of determining and processing a time delay for switching signal, especially for a safety-relevant controller.
