Abstract

L'invention concerne une installation de circuit pour la mesure de tension (T1, T2, T3, U) dans une commande électrique, en particulier une commande d'aiguillage, qui est conçue pour être activée en un mode de commande et en un mode de contrôle, au moins un commutateur (M1, M2, M3) étant prévu pour la séparation du circuit de mesure de tension en mode de contrôle. Pour atteindre de manière simple une liberté de rétroaction de la mesure de tension (T1, T2, T3, U) sur le circuit de courant d'actionnement (L1, L2, L3, N), l'invention prévoit que le commutateur soit conçu comme un relais (M1, M2, M3) électronique bidirectionnel commandé par un courant d'actionnement.
