Output Circuitry
The following is a simplified schematic of each AO-4-8 Output channel:
All 4 channels resemble the circuit shown above.
The outputs include an automatically resettable fuse. This fuse is designed to open when
an external device tries to extract more current than is available. They reset when the
current draw is back within range.
Note: In some extreme instances, the fuses may require that you remove power to
the module temporarily to reset their state.
