Hi All
I've got a circuit that has a 12V output from a ULN2803A for driving a relay, how ever I would like to opto couple it for extra safety.
Could you please advise if this circuit will work?
The optocoupler I thought of using is a TLP521-1, which has a input voltage 1.15V, probably not the best? wanting to use a DIP4 package for a easier board.
Thanks
