Title (EN) MICROPROCESSOR WATCH-DOG MONITOR FOR ELECTRONIC TRIP UNITS
(FR) MONITEUR CHIEN DE GARDE A MICROPROCESSEUR POUR ORGANES DE DECLENCHEMENT ELECTRONIQUES
Abstract: front page image
(EN)A microprocessor watch-dog monitor for electronic trip units includes an input transistor (Q1), a timing circuit (16), and a comparator circuit (18). The comparator circuit is formed of a first bipolar transistor (Q3) of the PNP-type conductivity and a second bipolar transistor (Q4) of the NPN-type conductivity.
(FR)Un moniteur chien de garde à microprocesseur pour des organes de déclenchement électroniques comprend un transistor d'entrée (Q1), un circuit de synchronisation (16), ainsi qu'un circuit comparateur (18). Le circuit comparateur est composé d'un premier transistor bipolaire (Q3) à conductivité de type PNP et d'un second transistor bipolaire (Q4) à conductivité de type NPN.
