OK, fellow electronics geeks. I need a digital relay controller. My current obsolete system will go dark in December so I need to find a replacement. I'm going to switch from high tech computer controller (Unifi mFi) to a digital relay.
I need a programmable digital relay that can do the following with 12vdc:
Sense a switch changing state. (probably from closed to open)
Wait 5 minutes.
If still open at 5:01 close the relay. (to power up a buzzer)
If the switch closes, stop counting and wait until after the next trigger cycle.
When the switch closes, open the relay.
Suggestion?
