Thank you very much for your reply!
So, would this setup (see picture) work?
As I wrote above:
- When output 3 is open (high), LED3 should light up.
- When output 3 is closed (low), LED3 should be out.
- Same with output 4/LED 4.
- LED1 is indicating, that there is 12V alive.
I need this setup, because the TRB142 will be stored in a box and I want the three LEDs to see the status from the outside:
- LED1: 12V is available
- LED3: Output 3 is open according to rule
- LED4: Output 4 is open according to rule
