Amatheminali okucindezela Iningi lezinhlobo ezijwayelekile zama-FTA ayatholakala ngezixhumi zetheminali yohlobo lokucindezela ezihambisana nezixhumi ze-FTA. Ukuze uxhumeke ku-FTA enezixhumi zetheminali yohlobo lokuminyanisa, okokufaka kwentambo kunemigqa engamamilimitha angu-75 (3/8 intshi), kanye noma kukhishwe amamilimitha angu-3 (1/8 iyintshi), kufakwe kutheminali yesixhumi, bese kubanjwa ngokuqinisa isikulufu setheminali ngayinye. Isixhumi samukela intambo exhumekile engu-0.3 kuye ku-2.5 mm2 (14 kuya ku-22 AWG). Futhi yamukela izintambo ezimbili ezixhumekile ezingu-1.0 mm2 (18 AWG), noma intambo eyodwa eqinile engu-3.5 mm2 (12 AWG). Umfanekiso 2-11 ungumfanekiso wesixhumi esivamile sohlobo lokucindezela. Amatheminali ama-Screw Amanye ama-FTA ajwayelekile ayatholakala anezixhumi zetheminali zohlobo lwesikulufu ezingamukela ukufakwa kwelugi yocingo ekugcineni kocingo. Bheka Umfanekiso 2-12 ukuze uthole umfanekiso wesixhumi esivamile sohlobo lwesikulufu esiqinile kanye noMfanekiso 2-13 ukuze uthole umfanekiso wesixhumi esivamile sohlobo lwesikulufu esikhiphekayo. Izixhumi ezixhunywayo Ama-FTA Ahlukaniswe Ngama-Galvanically Isolated awanazo izixhumi zetheminali yensimu ezigxunyekwe ngokuqondile ebhodini lesifunda eliphrintiwe lomhlangano njengoba kwenza ama-FTA avamile, kodwa esikhundleni salokho izintambo zasenkambu zixhunywe kuzixhumi ezixhumekayo zohlobo lokucindezelwa noma uphini lwe-crimp ezihambisana nesixhumi ku-Galvanic Isolation Module ngayinye. Izixhumi zohlobo lokucindezelwa zithatha usayizi ongu-0.3 kuya ku-3.5 mm2 (12 kuya ku-22 AWG) izintambo, kuyilapho izixhumi zetheminali yohlobo lwe-crimp zithatha usayizi wezintambo ezingu-0.5 kuya ku-2.5 mm2 (14 kuya ku-20 AWG). Amanani 2-14 kanye no-2-15 ayimifanekiso yohlobo lwe-crimp pin-type kanye nezixhumi zetheminali ezixhumekayo zohlobo lokucindezelwa, ngokulandelana. Izidingo zesignali ye-FTA I-schematics yezintambo, ukuxhumana kwetheminali, neminye imininingwane yokufaka izintambo kuhlobo ngalunye lwe-FTA kuxoxwa ngayo ngokuningiliziwe kubhukwana Lokufaka Lomphathi Wenqubo. Bheka leli bhukwana ukuze uthole izidingo ezikhethekile zokufakwa kwamanye ama-FTA, afana ne-Low Level Analog Input Multiplexer, i-Serial Device Interface, kanye ne-Serial Interface FTAs.
