Does anybody know device or circuit for Time Delay (except LM555 and ADM1087)? for example: Once i open the SW, the circuit will shut down after 10 sec. V+=24[V], I=40[mA] thanks very much))

Right now Vcc is 24V,but will change it. Are you saying that I required by circuit for 10 seconds is 40 mA. It is not adjusted to 10 seconds delay,can change it by adjusting C & R. 1/RC = 10 seconds. Pick to values for R and C. 50-100uF for C would be just fine. Attachments Capture.JPG 23 KB · Views: 60
