Abstract
La présente invention concerne les relais de télécommande centralisée en réponse à une tension alternative pulsée à une première fréquence. Le relais se caractérise essentiellement par le fait qu'il comporte des moyens pour fournir un signal à une seconde fréquence prédéterminée, un mélangeur pour recevoir et mélanger ledit signal à la seconde fréquence avec un signal représentant la première fréquence, un filtre recevant le signal de sortie du mélangeur et des moyens de sortie pour effectuer en fonction du signal obtenu à la sortie du filtre des opérations de commutation en conséquence. La présente invention trouve une application particulièrement avantageuse dans les relais de télécommande centralisée connectés au réseau de distribution d'énergie électrique.
