PH D-22T F-2727
Ukuhlolisisa
Isithiyo sokuphepha esihlukanisiweko ehlangothini lokuthola: i-PHD-22TF-2727, ukufakwa nokukhipha kwedijithali, ukufakwa okubili nokukhipha okubili.
Isithiyo esihlukanisiweko singatjhugulula iswitjhi yokutjhidelana nokufaka kokuthintana endaweni eyingozi kube siginali yokuthintana ye-relay bese idlulisela endaweni ephephileko.
I-relay yokukhipha ifakwe iswitjhi yokukhetha "VULA/VALA" ubujamo. Ukungezelela, kunesibonakaliso sokufaka esifitjhani namkha esivulekileko se-alamu, isekhethi inikela amandla wesensa yokufaka.
Umkhiqizo lo udinga umthombo wamandla wangaphandle we-20-35VDC.
Isitjengiso sesimo sesiginali sisethwe emkhanyweni obomvu nophuzi ukutjengisa ubujamo bokusebenza kwe-relay yokukhipha, lokha nayithusako khona-ke ukukhanya kuba bomvu, ngesikhathi sokusebenza okujayelekileko ukukhanya kuba mthubi.
* Umthombo wamandla webhasi, sibawa uqale isithasiselo ukuthola imininingwana.
