Abstract
L'invention a pour objet un procédé d'autosignalisation des défaillances d'un module d'automatisme statique de sécurité et un module d'automatisme le mettant en oeuvre. Selon l'invention on superpose aux tensions d'alimentation continues des tensions alternatives de fréquences différentes, on détecte la présence des battements entre lesdites tensions alternatives apparaissant sur lesdits circuits et on signale, à partir de la présence ou de l'absence desdits battements, les cas de non-concordance des états logiques des circuits. Application à la réalisation automatismes de sécurité.
