Input Selection Relay Board
I made this relay input board this afternoon and I would like your comments.
Should I leave unselected inputs floating ? As you can see, the relay's (+) has been connected together because they'll be controlled by a ULN2803 (which control relay's ground individually). Big pads are signal coming from RCA connector. The relay's common pin are connected together. Normally, only one relay is switched on (of course) Thanks ! Regards, |
