Ukuhlolisisa
I-isolator yesiginali yokukhipha iswitjhi yokuvikela ukugandeleleka itjhugulula isiginali yokufaka yokuthintana kweswitjhi nofana iswitjhi yokutjhidela ibe yi-relay output ngokusebenzisa i-isolation.
Ukutholwa kwephutha lelayini kukhishwa nge-relay ehlukileko begodu kutjengiswa lilanga le-LED phezulu kwemojuli. Iswitjhi yemodyuli isetjenziselwa ukukhetha isigaba sesiteshi nokuthi umsebenzi wokuthola iphutha lomlayini uyatlhogeka na.
Umkhiqizo lo udinga ukunikelwa amandla ngokuzijamela, begodu ukunikelwa kwamandla, ukungena nokukhipha amatheminali ahlukaniswe.
Iinqophiso
| Faka | |
| Isiginali yokufaka | Tjhugulula oxhumana nabo/ukutjhidela |
| Ivoltheji yokuphakela yesensa | Mayelana nama-8V |
| Izinga lokutjhugulula | |
| Iimfanelo zokufaka/zokukhipha: | |
| Ukufaka kwamanje okusesayithini | >2.1mA, okuphumako kuvaliwe, okutjengisa bona kuvuliwe; Lokha naku |
| Okukhiphako kuvamise ukuba "Vula"/"Vala" | Lokha iswitjhi yokudayela i-K1、K3 iseceleni "VULWE", umphumela wokudlulisela uthi "Ngokuvamileko uvaliwe". |
| Ukulawula ukutjhugulula kokuthintana | Lokha iswitjhi yokudayela i-K1、K3 iseceleni "OFF", umphumela wokudlulisela "uvuliwe ngokujayelekileko". Lokha iswitjhi yokudayela i-K2、K4 nayiseceleni elithi "VULWE", isekhethi ikhetha umsebenzi we-alamu ye-LFD yokukhanya okubomvu. |

Ubukhulu
Iintambo zokuhlanganisa
Tjheja:
1. Ukuphakelwa kwamandla wesitimela samandla kungumsebenzi ongakhetha kiwo. Abasebenzisi kufuze batjho indlela yokuphakelwa kwamandla lokha naba-oda. Sibawa uqale ukunamathiselwa ekhasini 89.
Ukutholwa kwephutha lelayini
Abasebenzisi bangakhetha ihlangothi elithi "VULA" leswitshi phezulu kwemojuli ukuvumela umsebenzi wokuthola amaphutha begodu batjengise i-alamu ngokukhanya okubomvu kwe-LED. Umtjhini wokufakwa endaweni>7mA, i-alamu yesekhethi emfitjhani (SC); Umtjhini wokufaka wendawo
