Ukuhlolisisa
Isithiyo sokuphepha esihlukanisiweko esinomsebenzi wokuvikela ukutjhinga kwemiphumela yokudluliselwa kweswitjhi, esihlukanisa begodu sidlulisele amatshwayo wokufaka avela ebantwini beswitjhi nofana amaswitshi aseduze eendaweni eziyingozi ukuya endaweni yokuphepha ene-output relay ngokusebenzisa isithiyo sokuphepha. Ukutholwa kwephutha lelayini kwenziwa ngokusebenzisa umphumela ohlukileko begodu kutjengiswa ku-LED ephezulu yemojuli. Iswitjhi yokudayela yemodyuli isetjenziselwa ukusetha ukufaka nokukhipha ngaphakathi kwesigaba nofana ukulawula okubuyela emuva, kanye nokuvumela nofana ukuvala umsebenzi wokutjengisa i-alamu yokuthola amaphutha welayini.
Umkhiqizo lo udinga ukuphakelwa kwamandla okuzijameleko, okuphakelwa kwamandla okuhlukileko, ukungena, nokukhipha amatheminali.
| Ukufaka endaweni eyingozi | |

Qaphela: Ukuphakelwa kwamandla wesitimela samandla kungumsebenzi ongakhetha kiwo. Abasebenzisi kufuze
tjho indlela yokuphakelwa kwamandla lokha nawu-oda.
Sibawa uqale ukunamathiselwa ekhasini 89.
Ukutholwa kwephutha lelayini(LFD)
Abasebenzisi bangakhetha ihlangothi elithi "VULA" leswitshi phezulu kwemodyuli
ukuvumela umsebenzi wokuthola amaphutha begodu utjengise i-alamu nge-
isibani esibomvu se-LED. Umtjhini wokufakwa endaweni>7mA, i-alamu yesekhethi emfitjhani (SC);
Umtjhini wokufaka wendawo
ukufaka kokuthintana kutlhoga umsebenzi wokuthola amaphutha (ukuphuka kwentambo, okufitjhani
isekhethi), i-resistor ye-22k Ω kufanele ixhunywe ngokufana emaphethelweni womabili
ye-switch, begodu i-resistor engu-680 Ω kufanele ixhunywe ngokulandelana (njengombana
kutjengiswa emfanekisweni wokufaka iintambo wokuthintana kweswitjhi II).
