Input Circuitry
The following is a simplified schematic of the MI-6 Milliamp Input module:
All six input pairs include their own automatically resettable fuses. These devices are
designed to open when sensing an over-current. They reset when the current supplied is
within range.
Note: In some extreme instances, the fuses may require that you remove power to
the module temporarily to reset their state.
