Fuse box with 6 monitored channels

This fuse box module used to be installed in my rack box project. It had a total of 6 channels, or outputs, each with fuses on both polarities. All fuses were monitored, meaning that if a fuse broke a failure LED would turn on and a fuse failed output activate.

Fuse box with 4 monitored channels

This fuse box module used to be installed in my rack box project. It had a total of 4 channels, or outputs, each with fuses on both polarities. All fuses were monitored, meaning that if a fuse broke a failure LED would turn on and a fuse failed output activate. In addition to the internal fuses, this module could also monitor an external fuse.
