Isishwankathelo
Kudibaniso olulula nolusebenzisekayo lwezinzwa kunye nee-actuators kwiimodyuli ze-S7-300 I/O
Ukugcina i-wiring xa ubuyisela iimodyuli ("i-wiring esisigxina").
Ngekhowudi yomatshini ukuphepha iimpazamo xa utshintsha iimodyuli
Isicelo
Umdibaniso wangaphambili uvumela uxhulumaniso olulula kunye nomsebenzisi-friendly we-sensor kunye ne-actuators kwiimodyuli ze-I / O.
Ukusetyenziswa kwesiqhagamshelanisi sangaphambili:
Iimodyuli zedijithali kunye ne-analog I/O
S7-300 CPUs compact
Iza kwii-20-pin kunye ne-40-pin ezahlukeneyo.
Yila
Isidibanisi sangaphambili sifakwe kwimodyuli kwaye sigqunywe ngumnyango wangaphambili. Xa utshintshela imodyuli, kuphela ikhonkco yangaphambili inqanyuliwe, ukutshintshwa kwexesha elide lazo zonke iingcingo ayimfuneko. Ukuze ugweme iimpazamo xa utshintsha iimodyuli, umdibaniso wangaphambili ufakwe ikhowudi ngomatshini xa uqala ukufakwa ngaphakathi. Emva koko, ingena kuphela kwiimodyuli zohlobo olufanayo. Oku kuthintela, umzekelo, i-AC 230 V yesiginali yokufaka ifakwe ngengozi kwimodyuli ye-DC 24 V.
Ukongeza, iiplagi zine "isikhundla sangaphambili sokuzibandakanya". Apha kulapho iplagi ixhwilwa kwimodyuli phambi kokuba uqhagamshelwano lombane lwenziwe. Isidibanisi sincamathela kwimodyuli kwaye sinokufakwa intambo ngokulula ("isandla sesithathu"). Emva komsebenzi wocingo, ikhonkco ifakwe ngakumbi ukuze idibanise.
Isidibanisi sangaphambili siqulathe:
Abafowunelwa boqhagamshelwano lweengcingo.
Ukukhululeka koxinzelelo kwiingcingo.
Seta kwakhona iqhosha lokuseta kwakhona ikhonkco langaphambili xa utshintsha imodyuli.
Ungeniso lokuncamatheliswa kwesiqalelo sekhowudi. Kukho izinto ezimbini zokukhowuda kwiimodyuli ezinoncamathiselo. Izinto ezincamathelayo zitshixeka xa isinxibelelanisi sangaphambili siqhagamshelwa okokuqala.
Isidibanisi se-40-pin ngaphambili siza kunye nesikrufu sokutshixa sokuncamathelisa kunye nokukhulula isinxibelelanisi xa utshintsha imodyuli.
Izihlanganisi zangaphambili ziyafumaneka kwezi ndlela zilandelayo zoqhagamshelwano:
Screw terminals
Iitheminali ezilayishwe entwasahlobo
