Ukubuka konke
Isithiyo sokuphepha esihlukanisiwe esinomphumela wokudlulisa okufakwayo kokushintsha, esihlukanisa futhi sidlulise amasignali okufaka kusuka koxhumana nabo bokushintsha noma izinkinobho zokusondela ezindaweni eziyingozi kuya endaweni yokuphepha ngesithiyo sokudlulisa okukhiphayo ngesithiyo sokuphepha. Ukutholwa kwephutha lomugqa kufezwa nge-LED phezulu kwemodyuli. Iswishi yokudayela yemodyuli isetshenziselwa ukusetha okokufaka nokukhiphayo ngaphakathi kwesigaba noma ukulawula okuphambene, kanye nokunika amandla noma ukukhubaza umsebenzi wokubonisa i-alamu yokuthola iphutha lomugqa.
Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okuneziphesheli zamandla ezihlukanisiwe, okokufaka, kanye nokukhipha.

Qaphela: 1. I-PHD-12TF-277 ayifaki ingxenye yokufaka 2
2. Ukunikezwa kwamandla kwesitimela sikagesi kungumsebenzi ongawukhetha.
Abasebenzisi badinga ukucacisa imodi yokunikezwa kwamandla lapho be-oda.
Sicela ubheke okunamathiselwe ekhasini 89.
Ukutholwa Kwephutha Lomugqa (LFD)
Abasebenzisi bangakhetha uhlangothi oluthi "VULIWE" lweswishi phezulu kwemojuli ukuze kusebenze umsebenzi wokuthola amaphutha futhi kuboniswe i-alamu nge- isibani se-LED esibomvu. Ukufakwa kwamandla kagesi >7mA endaweni, i-alamu yesikhathi esifushane (SC);
I-input current esendaweni okokufaka kokuthintana kudinga umsebenzi wokuthola amaphutha (ukuphuka kwentambo, ukufinyela isekethe), i-resistor engu-22k Ω kufanele ixhunywe ngokuhambisana kuzo zombili izinhlangothi yeswishi, kanye ne-resistor engu-680 Ω kufanele kuxhunywe ngochungechunge (njengoba kuboniswe kumdwebo wocingo wokuxhumana kweswishi II).
