El circuito presentado hace uso de dos módulos híbridos (ver artículos en el sitio) para accionar una carga conectada al relé en el colector del transistor BC548 (pin 3 del 4017. El circuito tiene un alcance que depende del lugar en que opera (ruido, interferencia, , etc.), pero normalmente estará en torno a 10 metros. La alimentación del transmisor se realizará con tensiones de 9 o 12 V según el relé, observando que para el receptor la tensión es de 5 V, regulada por un diodo zener. el transmisor, la tensión de funcionamiento es de 3 V, pero la alimentación del circuito se puede hacer con 6 V, pues existe un diodo zener regulador. Se pueden conectar diversas cargas en las salidas del 4017 para obtener el accionamiento secuencial. de las salidas puede dejarse libre para que en ella no tengamos accionamientos. En las figuras tenemos el diagrama del transmisor, del receptor y del pinado de los módulos DHAY usados en el proyecto.
