Abstract

L'invention est relative à un dispositif interface à sécurité positive intrinsèque. L'état tout ou rien d'un contact inverseur provoque la mise en circuit dans une ligne alimentée par une tension alternative de l'une ou de l'autre des diodes d'une paire de diodes de polarité inverse et l'apparition d'une tension positive ou négative appliquée à une logique à pannes orientées et à un système d'acquisition indicateur du bon état du capteur et de la ligne. Le dispositif peut être appliqué à des systèmes de sécurité.
