1 second to 30 minute 12Vdc push button activated delay timer board with reset button and a relay output (C, NO, NC). 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. 6 minutes and the other covers from 1 second to approx. 30 minutes. LED status indicator.
The board uses a traditional 555 timer circuit that shows how to extend the timing period to the maximum.
