Мислим да сам нашао две грешке на Комитартовој плочи, НЕ555 пин 4 би требало да се повеже на 680к отпорник, а диода је окренута уназад.

Како изгледа остатак?

imaš pravo. usput,ne bi bilo loše koristiti MJE350 umesto BD140. diode paralelno špulnama smanjuju povratnu EMS,ali i produžuju vreme otvaranja kontakata releja. redni tim diodama nije loše staviti otpornike vrednosti otpora kojeg su i sami kalemovi releja.

Bilo koji. Pin COM2 ispod releja ne igra neku ulogu, više je tu da ga fiksira.

Jednom sam otvorio jedan sličan rele. I šta vidim unutra, na izgled čelične opruge malo zahrđale i kontakti od nekog žućkastog metala. Pravac kanta. Nije ta firma, nego neki drugi Kinez sa ebay. Valjda su dobri ti u Kelco.

Takve sam i mislio da stavim ali nisam nasao fajlove za izradu  za ovu zastitu sa Zobel-om. 
Ako neko ima fajlove, pdf  za stereo ili mono varijantu sa zobelom ove zastite bio bih veoma zahvalan. Ipak mi je u interesu da budu bolji releji  Smile

Nisam bas sa vremenom da crtam, ali ako mozes sacekat 2-3 tjedna odradit cu tu zastitu sa tim relejima i hmapovom bjt+zener stabilizatorom gdje se racuna samo rx za HV pin....koliko ti je ulazno napajanje? 12VAC ili visse?

Ma mogu cekati Smile 
Mogu li ovi releji posto su navedeni od 24v 16A a ovi su 12v ali 10A
 http://www.kelco.rs/katalog/komponente.p...upweb=5640
 Izvodi sa trafoa trenutnog su 12VAC ali bolje da ima i da mogu ako nabavim  neki trafo koji nema dodatne izvode pa hmapovom bjt+zener stabilizatorom gdje se racuna samo rx za HV pin da resim problematiku sa višim naponom.
