Abstract

DISPOSITIVO DE CELULAS DE RAYOS INFRARROJOS DESTINADA A PILOTAR CUALQUIER RELE ESTATICO O ELECTROMAGNETICO PARA MANDO DE POTENCIA EN GENERAL. FORMADO POR UN PAR DE FOTOCECULAS (1 Y 2), UNA DE LAS CUALES ES EMISORA (1) Y LA OTRA RECEPTORA (2). LA FOTOCELULA EMISORA (1) INCLUYE UN PROYECTOR (3) DE RAYOS INFRARROJOS O DIODO LASER, ACCIONADO EN REGIMEN DE IMPULSOS POR UN GENERADOR DE IMPULSOS (4). UN SENSOR (6) RECIBE LOS IMPULSOS LUMINOSOS Y EXCITA, A TRAVES DE UN AMPLIFICADOR (7), UN MULTIVIBRADOR MONOESTABLE (8) CUYA SEÑAL, OPORTUNAMENTE AMPLIFICADA (9), ESTA EN CONDICIONES DE EXCITAR UN RELE.
