Thanks CrossRoads for your suggestion. Simple to develop, but my circuit must be installed inside other device and I haven't space to place about 14-15 relays :slight_smile:

I readed the datasheet that sais Telecommando, the CD4066. Seems an interesting solution, but for simplicity and availability of components in my city, I prefer using a few simple optocoupler. Do you know any recommended model? Can it be a valid 4N35 or TIL116?

Thanks!!!
