Abstract

L'invention concerne un système de commande basse tension comprenant un contrôleur présentant au moins une sortie de bus de puissance CC, une sortie de bus d'adresses unidirectionnel commun, et une unité de traitement programmable connectée au bus d'adresses unidirectionnel commun et en communication avec une unité de mémoire du contrôleur. Une pluralité de charges d'éclairage CC comprenant chacune au moins un élément d'éclairage CC et un circuit de modulation pouvant être commandé par un PLD ou ASIC associé. Chaque circuit de modulation module une tension reçue en provenance du ou des bus de puissance CC tel que requis par son élément d'éclairage CC. L'unité de traitement programmable utilise des instructions de programme stockées sur l'unité de mémoire du contrôleur pour commander sélectivement les circuits de modulation des charges d'éclairage CC par l'intermédiaire du PLD ou de l'ASIC associé à chacun des circuits de modulation. Au moins un dispositif d'entrée commande les circuits de modulation des charges d'éclairage CC indépendamment du contrôleur par l'intermédiaire du PLD ou de l'ASIC.
