 		 #64200 - RE: Drive a relay-Sorry for incorrect c
Responding to: ???'s previous message
hi,
indeed, Steve.
Here we have done a project where it needs to control relays with MCU with one more limit: +5V and +12V sources are isolated from each other (have not common ground).
So we connected MCU pins to optocouplers and their outputs to ULN2803 which swithes relays.

Regards,
Oleg
