3.17. Fuses protection
The VSBC-6862 offers a flexible I/O extension facility through its quad IP module interface. Therefore
some cautions must be taken to avoid hardware damage in case of short circuit.
This function is handled by a set of on-board fuses.
These fuses are thermal controlled, when a short-circuit arise, the fuse will automatically break the
circuit. When it will be cold, it becomes again normal.
