Abstract
A time delay fault device includes an integrated circuit (IC) having an electronic circuit having a fault indicator signal output and a time delay circuit having an input connected to the fault indicator signal output and an output to provide a delayed fault indicator signal output, the time delay circuit being responsive to an external voltage from a resistor capacitor network coupled to the delayed fault indicator signal output to set the time delay of the delayed fault indicator signal.
