Solid-state outputs are extremely reliable when used correctly, but they will burn out if they're shorted out or wired wrong. This is the chip that's used inside our BooBox Flex, BooBox FlexMAX and BooBox 8+. The chips are mounted in sockets, so the old one can be easily removed and replaced, no soldering necessary.
Did I Blow My Chip?
If some or all of your outputs turn on and don't turn off your chip is blown.
If none of your outputs turn on yet everything else seems to be working fine, your chip is blown.
If you saw smoke and your controller smells funny, your chip is definitely blown.
