Ukubuka konke
Isithiyo sokuphepha esihlukanisiwe esinomsebenzi wokuvikela ukukhuphuka kwe-switch input transistor output, ehlukanisa futhi idlulise izimpawu zokufaka ezivela koxhumana nabo be-switch noma izinkinobho zokusondela ezindaweni eziyingozi ziye endaweni yokuphepha nge-transistor output ngesithiyo sokuphepha. Ukutholwa kwephutha lomugqa kufezwa nge-LED phezulu kwe-module. I-dial switch ye-module 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, okuneziphetho zokunikezwa kwamandla ezihlukanisiwe, okokufaka, kanye nokukhipha.

Qaphela: Ukunikezwa kwamandla kwesitimela samandla 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).
