One of the centralized monitoring circuits for fuse blowing

Using the centralized fuse blowing monitor, the on-duty personnel can promptly discover which load's fuse is blown and
deal with it in a timely manner. This is very important for reducing power outage time and ensuring the safety of load equipment.
    The circuit is shown in Figure 13-61. It is used for centralized monitoring of DC power supply systems. Only three paths are drawn in the figure, and they can
be increased or decreased according to actual needs.
