Le module de détection d'entrée comprend une unité de détection, une première unité de traitement et une unité de sortie. L'unité de détection détecte le premier signal physique pour générer un signal analogique. La première unité de traitement traite numériquement le signal analogique pour générer le signal de modulation d'impulsions en largeur. L'unité de sortie comporte n broches de sortie de signal pour délivrer le signal de modulation d'impulsions en largeur et deux broches de sortie d'alimentation électrique pour délivrer un signal d'alimentation électrique. Le module de sortie comprend une unité d'entrée, une seconde unité de traitement et une unité d'excitation. L'unité d'entrée comporte n broches d'entrée de signal pour recevoir le signal de modulation d'impulsions en largeur et deux broches d'entrée d'alimentation pour recevoir le signal d'alimentation électrique, et est directement couplée à l'unité de sortie. La seconde unité de traitement traite le signal de modulation d'impulsions en largeur pour générer un signal de commande. L'unité d'excitation délivre le second signal physique sur la base du signal de commande.
