3085_2 - 555 Monostable Timer
The
kit is a traditional 555 timer circuit that shows how to extend the timing
period to the maximum.
The relay is activated when the START button is pressed and turns off
either after time-out or by pressing RESET. The delay time period is adjusted
via the onboard trimpot.
Two capacitor values are provided to give different timing periods. The
first gives a timing period of <1 second to approx. 10 minutes and the other
covers from 1 second to approx. 20 minutes. LED status indicator.
