This implementation of relays in the NetEQ circuit is confusing to me.
Why are we dropping the voltage to bring it back up with a transistor before reaching the relay? VLR+ = 12V, so why not go direct?
And a bonus question.
I sort of blocked out the LED when looking at the schematic at first, so I spent a little time trying to figure out why there were two values instead of just a single drop resistors, but.
I realized 1K is there to drop the voltage for the LED, but is there any advantage to placing it before the switch?
