Abstract

Un circuit de commande optique et un circuit de commande électrique comme un circuit de commande de moteur sont interconnectés par une interface électro-optique. Un commutateur optique passif situé dans le circuit optique à une position éloignée du circuit électrique est actionné physiquement pour produire un changement dans l'état de la transmission optique du circuit optique. € l'interface électro-optique, le changement dans l'état de la transmission optique du circuit optique est détecté et déclenche un changement dans l'état de la transmission électrique du circuit électrique. Conçus en tant que boutons-poussoirs ARRT ET MARCHE (STOP et START), une paire de commutateurs optiques passifs à une position éloignée du circuit électrique réduit le risque que les circuits de commande d'actionnement du moteur, etc. causera la formation d'un arc, et, dans les environnements dangereux, une explosion.
