automatizare poartai culisanta

Recommended Posts

trebuie sa le masor hfe-ul sau nu are legatura cu asta?

Da, are legatura, este valabil si pentru Mos, chiar si valorile rezistentelor, dar nu stiu daca este asa importanta o diferenta de cca.14%.

Ok, multumesc pentru ajutor. Probabil voi mai reveni si cu alte nelamuriri. O seara placuta!

Cine imi poate spune cu ce pot inlocui circuitele integrate care codifica si decodifica semnalul?

Integratele respective nu le poti inlocui pentru ca, din ce stiu, nu au echivalent.

macar alte integrate care codeaza si decodeaza un semnal stiti? Daca stie cineva astfel de circuite va rog sa nu ezitati sa postati. Va multumesc!

HT12E(codor) si HT12F(decodor).

Eu nu m-am incurcat cu montaje electronice complexe si am facut-o din componente avute de mine la dispozitie si cumparate.

Poarta mea automatizata este facuta dintr-un motor de masina de spalat automata cuplat la un reductor melcat unde comanda se face printr-o alarma auto cuplata la relee de comanda. Schema nu o am la indemana dar cine are cunostinte de electrotehnica poate intui conexiunile interblocabile si de comanda al motorului. La aceasta poarta i se mai poate monta si o bariera cu fotocelula de siguranta la inchiderea accidentala.
