Ukusetshenziswa kwe-multi-channel DC electronic Load ekuhlolweni kwe-PLC

I-PLC isilawuli sekhompiyutha yedijithali esetshenziswa ekulawuleni okuzenzakalelayo, esingalayisha, sigcine futhi sikhiphe imiyalelo yokulawula. Njengedivayisi yokulawula evamile ehlanganisa ubuchwepheshe bekhompiyutha, ubuchwepheshe bokulawula okuzenzakalelayo kanye nobuchwepheshe bezokuxhumana, i-PLC isetshenziswe kabanzi ezimbonini eziningi ezifana nezimoto, ugesi, insimbi, izimayini, i-petroleum, namakhemikhali.

Izinto zokuhlola ze-PLC ngokuvamile zihlanganisa okokufaka nokuphumayo, ingqondo yokuhlela, ukuxhumana, ukuxilonga amaphutha, njll. Njengengxenye eyinhloko yokuqaphela ukwenziwa kokulawula, ikhono lokushayela nokunemba komthwalo weyunithi yokukhiphayo kuthinta ngokuqondile ukusebenza kokusebenza kwe-PLC. Ngakho-ke, ukuhlolwa kweyunithi yokuphuma kwe-PLC nakho sekungenye yezinto abagxile kuzo abakhiqizi.

● Izidingo zokuhlolwa kwe-PLC nezixazululo zokuhlola ezivamile

Thatha umkhiqizi we-TOP1 PLC womhlaba njengesibonelo. I-S iyinkampani ehamba phambili emhlabeni jikelele yokufaka ugesi, ezishintshayo kanye nedijithali. Ihlinzeka ngezixazululo eziholayo embonini emkhakheni wokuphehla ugesi nokudluliswa nokusabalalisa, ingqalasizinda, i-automation yezimboni, ukushayela kanye nesofthiwe. Le nkampani ibe ku-500 ephezulu emhlabeni iminyaka eminingi ilandelana. Ekuqaleni, ikhasimende lalidinga ukuhlola ukusebenza kweyunithi yokukhishwa kochungechunge lwayo lwe-S PLC, futhi libeke phambili lezi zidingo zokuhlola ezilandelayo:
01 Amamojula amayunithi amaningi adinga ukuhlolwa ngesikhathi esisodwa: Ukukhishwa kwe-PLC eyodwa amashaneli ayi-8, futhi amanye amamodeli e-PLC anenqwaba noma amakhulu eziteshi. Lapho ama-PLC amaningi edinga ukuhlolwa, lokhu kubeka izidingo eziphakeme ekuhlanganisweni kwemishini yokuhlola;
02 Ukunemba okuphezulu, okokusebenza kokuhlola okuhlelekayo okunebanga elibanzi kuyadingeka: Okukhiphayo okulinganiselwe kwe-PLC ngu-24Vdc/750mA, futhi ububanzi bokuphumayo bungu-20.4V~28.8V. Ngokuvamile, idivayisi yokuhlola idinga ukusetha ngokunembile futhi ifunde emuva i-voltage ephumayo kanye ne-output voltage.

Ekuqaleni, ikhasimende u-S lasebenzisa izinto ezivimbela usimende kanye nemithwalo ye-elekthronikhi yedeskithophu evamile ukuze ihlole ukusebenza kweyunithi yokuphumayo, eyayinezinkinga ezifana nokunganemba kokukhishwayo okunganele kanye nenani elikhulu lempahla yokuhlola ethatha indawo.
Ukunemba okukhiphayo okunganele: Izinqamuleli zikasimende zijwayele ukukhukhuleka ngenxa yokushisa ngaphansi kwezimo zokusebenza zesikhathi eside, ezingakwazi ukuqinisekisa ukuzinza nokunemba kwenani lokuhlola;
Izinto zokuhlola zithatha isikhala: Uhlaka olujwayelekile lwedeskithophu olulayisha 19-inch 3U lusekela iziteshi ezifika kweziyisi-8, kodwa ukuhlolwa kwama-PLC angu-2 kuphela kudinga isikhala esingu-6U.

● Isixazululo sokuhlola okunembayo esiphezulu se-NGI seziteshi eziningi

Kumakhasimende e-S, babe nezinkinga zokuhlola ekuqaleni. Umthwalo we-DC kagesi we-N6180 ohlinzekwa yi-NGI onamashaneli amaningi ungaxazulula izinkinga zawo ngokuphelele.

Iziteshi ezingu-19 zingahlanganiswa esikhaleni se-3U, futhi isikhala esithathwe inombolo efanayo yamashaneli singu-1/3 kuphela womthwalo wedeskithophu wendabuko;
Eyamanje idizayini enamabanga amabili enemba efinyelela ku-0.02%+0.05%FS, engaqinisekisa ukuthi iphutha lokusetha nelokufunda emuva ngeke lidlule u-1mA uma umthwalo wamanje ungu-750mA, ohlangabezana nezidingo zokuhlola ngokugcwele. uhla lwama-PLC aphezulu, aphakathi nendawo naphansi;
Isekela ukufundwa kwe-voltage enembayo ephezulu, ngaphandle kwesidingo sokusebenzisa i-multimeter yedijithali ukukala i-voltage ephumayo, ukonga izindleko ekuthengeni nasekufakeni izintambo.
