Am facut eu exact cu IN-9 cumparate de pe http://www.rutubes.com

Deoarece are un histerezis relativ mare intre aprins si stins complet, trebuie obligatoriu un circuit care sa-l tina tot timpu aprins putin, cu un operational si un tranzistor. (altfel functioneaza groaznic)

schema din elektor are un microcontroller care face si o conversie AD, primul film. La prima vedere pare ca functioneaza bine, am sa mai studiez schema.

Nu stiu acea schema dar uite un exemplu de circuit care trebuie folosit la IN-9: http://roze.ridorana.se/old/bilder/2xBa ... v4.sch.png . La IN-13 nu e nevoie ca are al treilea electrod, care tocmai asta face, tine descarcarea amorsata (la curent foarte mic)

 

Vezi ca sunt multe confuzii pe net intre IN9 si IN13. IN9 are 2 pini iar IN13 are 3 pini si se ataca diferit. E plin de scheme care dupa titlu sunt pentru IN9 iar daca studiezi schema e de fapt pentru IN13.

Se fabrica cel din revista Elektor, este un microcontroler care il poti comanda si direct de la ei fara sa te mai complici cu programarea. Schema o gasiti in numarul 11 din 2012 la pagina 30
