Ingcaciso yeMveliso

I-Feimu Technology inikezela ngo-Allen Bradley 1794-IF8IH. Le mveliso yenzelwe ngokukodwa ukuguqula imiqondiso eqhubekayo esuka kwiindawo zoshishino - ezifana nobushushu, uxinzelelo okanye ukuhamba - kulwimi lwedijithali umlawuli anokuqonda. Yahlukile kwiimodyuli eziqhelekileyo zohlobo lwangoku. Inoxanduva olukhethekileyo lokuphatha iisignali ezizimeleyo kwaye inamandla kakhulu okuchasa ukuphazamiseka. Sihlala sigcina le mveliso kwisitokhwe apha ukuze sigqibezele eyona nxalenye ibalulekileyo yephazili kwinkqubo yakho yeFlex I/O, ukuze ungafuneki uncedo kuye wonke umntu wale modyuli enye.

Ukusebenza kweMveliso

Lo mzekelo we-Allen Bradley 1794-IF8IH uxhasa i-protocol yonxibelelwano ye-HART, oku kuthetha ukuba ayikwazi ukufunda kuphela i-4-20mA ixabiso langoku, kodwa "inokuthetha" kunye nezixhobo ezihlakaniphile kwi-site ukufumana ulwazi olungakumbi lokuxilonga ngaphakathi kwezixhobo. Ukuchaneka kokuguqulwa kwayo kuphezulu kakhulu, kukwazi ukubamba nolona tshintsho luncinci kwintsimi. Kwaye kumzi-mveliso ololo hlobo lwemekobume ye-electromagnetic imoshakele ngakumbi, ukusebenza kwayo yodwa kudlala indima enkulu, kunokuthintela ngokufanelekileyo umqondiso wokuphazamiseka wangaphandle wokumosha idatha, ukuqinisekisa ukuba idatha ethunyelwe kwi-PLC iyinyani kwaye ithembekile.

Iimpawu zeMveliso

Lo ka-Allen Bradley 1794-IF8IH unento ekhethekileyo kakhulu, eyona "i-channel-to-channel isolation". Iimodyuli ezininzi eziqhelekileyo zinezizathu eziqhelekileyo kumajelo amaninzi, ngoko ke ukuba ucingo olunye lomhlaba luxhunywe ngokungalunganga okanye kukho ukuphazamiseka okunamandla, zonke iziteshi zinokuchaphazeleka. Kodwa lo wahlukile. Ijelo ngalinye lizimele lodwa. Nokuba elinye ijelo liyasilela, aliyi kuchaphazela amanye. Ifaneleke ngokukodwa ezo ndawo ezinemithombo yemiqondiso enzima kunye neemeko ezimbi zokumisa. Olunye uphawu kukuba inamandla kakhulu kwaye yenza ubushushu obuncinane kakhulu. Nangona ifakwe kwikhabhinethi evaliweyo, akukho mfuneko yokukhathazeka malunga nokutshatyalaliswa kokushisa okungahambi kakuhle kunye nokushisa kwendawo ejikelezileyo.
