required:
user interface with screen/buttons
minimum 1 relay with protection circuitry
nice to have options:
keypad (pin)
ethernet/802.11/bluetooth communications
RFID FOB reader (alternative to pin security)
And of course, I'd like to pay practically nothing for it, but
realistically, has anyone had any experiences with an affordable unit
which will be able to effect time control of a solenoid??? Any pointers
appreciated ...
Cheers,
Rob.
