The Watchdog board is a real hardware watchdog turning off the power of the PC if it is not triggered within 25 minutes. It also can act as a small UPS system if a batterie has been ordered. It is important to know that this board measures the temperature around and it is turning on the PC only if the temperature is above 10° to protect the harddrives.
