Abstract
A power supply adapted to provide power for one or more field devices over a protocol bus based network, such as a fieldbus network, which includes an oscillator circuit and a power control switch mounted at the output of a conditioned power supply. The oscillator circuit is adapted to detect a cable fault such as a short circuit. When a cable fault is detected, the oscillator circuit sends a signal to the power control switch to stop the power supply from feeding current to the network and to activate an alarm signal to alert a host of the cable fault.
