The problem with correcting the inversion is that if you’re using this board to run relays and you connect one side of the coil to HV and the other side to the outputs of this board, the relays will always turn on when the power is switched on. This is a Bad Thing™ because it doesn’t fail safe.
I cannot think of a way to run this in a safe way with this board, since the 10k pullup resistors won’t supply enough power to run the coil of a relay.
Can anyone think of a solution? I’m a little stuck currently!
No public wish lists :(
