CIRCUIT LOGIQUE DE PUISSANCE A DOUBLE FONCTION, ET/OU, ET APPLICATION A UN DISPOSITIF DE TEST

摘要

The circuit comprises a series of diode bridges (F1,F2...) and one relay (R). Each bridge's AC input terminal is connected to an input terminal of the circuit. If some input terminals are not used, they are connected together. The positive output terminals of these bridges are connected to each other and to one input terminal of a relay (R). The bridges' negative output terminals are connected to each other and to the other input terminal of the relay. One OR output terminal (SOU) is connected to one relay's input terminal. One AND output terminal (SET) is the relay's output terminal. The other OR and AND outputs are at the common potential. The circuit is capable of functioning when the voltages at the inputs differ. If such is the case, the output (SOU) acquires the highest value input voltage.
