I understand you perfectly and I will explain to you, when they changed the programmers of the golf course, they threw away all the relays and others to be recycled and I will have 15 or 20 modules of 8 relays, which have an integrated displacement register, and I annulled the system and put them with transistors. and a crude arduino program. and one day I found you and said I want.
I do all this to recycle what I have, if I were to buy it, I would buy the correct one.
I attach a photo, I still have one with shift register on, but if pcf gets stuck, I don't try the shift register.
Thank you very much
