I-PHD-12TF-288
Uhlolojikelele
Isithiyo sokuphepha esisodwa ngasohlangothini lokutholwa: PHD-12TF-288, okokufaka kwedijithali nokuphumayo, okokufaka okukodwa kanye nokuphuma kabili.
^ Umgoqo ohlukanisiwe ungaguqula iswishi ye-proximity kanye nokokufaka kokuxhumana endaweni eyingozi kusignali yokuphumayo ye-transistor bese uyidlulisela endaweni ephephile. I-transistor ephumayo phakathi kwe-ec ifakwe umshini wokukhetha "isigaba esihlanekezelwe / isigaba esivamile" , ngaphezu kwalokho, kukhona isifunda esifushane sesignali yokufaka noma inkomba ye-alamu yesifunda evulekile, isifunda sihlinzeka ngokunikezwa kwamandla enzwa yokufaka.
^ Lo mkhiqizo udinga ukunikezwa kwamandla kwangaphandle okungu-20-35VDC.
^ Inkomba yesimo sesignali isethwe ekukhanyeni okubomvu nokuphuzi ukuze ibonise isimo sokusebenza kwe-relay ephumayo, uma ingeyethusa bese ukukhanya kuba bomvu, ngesikhathi sokusebenza okuvamile ukukhanya kubaphuzi.
* Ukunikezwa kwamandla ebhasi, sicela ubone isithasiselo ukuze uthole imininingwane.
