Okokufaka
Okokufaka kokuphepha Kuhlelo Lokuphepha kuzokhipha amandla kokufakwayo kohambo noma okokufaka kwe-analogi.

Okokufaka kwedijithali
Ukukhipha amandla okokufaka kohambo (ngokuvamile okubizwa ngokuthi i-fail-safe) kuzosetshenziswa kukho konke okokufaka kwedijithali kokuphepha. Inani lamasiginali okuqapha ukuphepha adingekayo kupharamitha ngayinye yokuphepha izoncika kakhulu ezingeni lobuqotho bokuphepha (ukuhlelwa kokuphepha) okudingekayo ukuze kufinyelelwe, umjikelezo wokuhlola ubufakazi obungu-100% odingekayo kanye nezinga lokuxilonga elitholakala kudivayisi yasendle.
Konke okokufaka kwedijithali kokuphepha kuzoxhunywa ekhadini lokunqanyulwa kwe-Digital Input. Lapho izinga lobuqotho bokuphepha lidinga ukuthi inzwa yenkundla engaphezu kweyodwa eqaphe ipharamitha yokuphepha, ngayinye yalezi zinzwa kufanele, lapho kusebenza khona, ifakwe intambo ukuze ihlukanise Amakhadi Okunqamula. Ingxenye ye-Simplex yekhadi lokunqamula (isibonelo, amafuse) kufanele icatshangelwe ukuze kuhlaziywe ukwethembeka njengengxenye yeluphu yasendle.

Ikhadi Lokunqamula lizoxhunywa ku-Triguard SC300E Input Module ngekhebula yesistimu evamile exhuma kusokhethi ekhadini elifanele le-Adapter Yokulungisa Okushisayo noma indawo ye-chassis.
Ngekhadi le-adaptha yokulungisa okushisayo, lapho kudingekile, kanye nesixhumi sendiza yangemuva ye-chassis isignali yokufaka ixhunywe endaweni emisiwe yesikhala yokufaka yedijithali lapho kuzotholakala khona Imojuli Yokufaka Yedijithali.
Zonke izikhala ze-chassis futhi, lapho kudingekile, izikhala zikazakwethu wokukhanda ezishisayo ezilungiselwe Imojula Yokufaka Yedijithali kufanele futhi zibe nokhiye be-polarization abafakelwe futhi balungiselwe lolu hlobo lwemojuli njengoba kucaciswe ku-Module kanye ne-Chassis Users Manuals.
Lapho izinga lobuqotho bokuphepha lidinga ukuthi izinzwa ezihlukene zisetshenziselwe ukuqapha amapharamitha okuphepha afanayo kufanele amiswe ukuze ahlukanise Amamojula Okufakwayo Kwedijithali lapho kusebenza khona.

Okokufaka kwe-analogi
Ama-analog transmitters asetshenziselwa ukuqapha amapharamitha okuphepha futhi ahlinzeke ngokwemvelo ngezinga elikhulayo lokuxilonga ngokuphathelene nokokufaka kwedijithali okungaphumeleli kalula. Amasignali e-analog ahlala ehlinzeka ngamavelu phakathi kwesethi yebanga lokusebenza. Kuma-transmitters ahlobene nokuphepha lokhu kufanele kube ngu-4-20 mA noma 1-5 volts okuvumela inkomba yephutha ngezansi ithi 3 mA (0.75 V) kanye no-20 mA (5 V). Uma kudingeka ukuthola ububanzi obuningi, imojuli yokufaka engu-0-10 V kufanele isetshenziswe. Wonke amaphutha agadiwe avela kumasiginali e-analogi kumele asetshenziswe isoftware yohlelo ukukhiqiza imiphumela ephephe kakhulu (isibonelo, isidlulisi esihlulekile sifuna ukuvala shaqa).
Inani lama-analog transmitters asetshenziselwa ukuqapha ipharamitha yokuphepha lizoncika ezingeni lobuqotho besistimu (ukuhlelwa kokuphepha) kwesidingo seluphu, umjikelezo wokuhlola ubufakazi obungu-100% beluphu kanye nezinga lokuxilongwa elitholakala kumthumeli.
Isiginali ye-analogi yenkambu ixhunywe ekhadini lokunqamula okokufaka kwe-Analogi. Lapho amaleveli obuqotho bokuphepha edinga ukuthi kusetshenziswe isidlulisi esingaphezu kwesisodwa ukuze kuqashwe ipharamitha yokuphepha, amasiginali okufakwayo e-analogi engeziwe kufanele afakwe intambo ukuze ahlukanise Amakhadi Okunqamula lapho kusebenza khona. I-Simplex circuitry ekhadini lokunqanyulwa kufanele ibhekwe njengokwethenjelwa njengengxenye ye-loop yokudlulisela (isibonelo, ama-fuse kanye nezimbangi zokuqapha lapho zifakwe khona). Bheka Umfanekiso B-1.
Isignali ixhunywe kusuka ekhadini lokunqanyulwa kuya kumojula yokufaka ye-Triguard SC300E ngekhebula yesistimu evamile, exhuma kusokhethi ekhadini elifanele le-Adapter Yokulungisa Okushisayo noma isixhumi se-chassis.
