Allen Bradley 1746-NO8V

Ngaba ukusebenza kwe-activator yolawulo lwemizi-mveliso kugqwethiwe?

Njengomthengisi oqeqeshiweyo, iTekhnoloji yeFeimu ibandakanyeke ngokunzulu kwicandelo lolawulo lwamashishini iminyaka emininzi. Kutshanje siphehlelele imodyuli ye-Allen Bradley 1746-NO8V 8-channel ye-analog voltage output module. Siyaqonda ukuba kulawulo oluzenzekelayo, isignali yokuphuma ifana ne-baton, ukuba ayilawulwa ngokuchanekileyo, ukusebenza kwe-actuator kuya kuphazamiseka, kuchaphazela kakhulu ukuchaneka kwemveliso. Asithengisi nje imodyuli, kodwa sibonelela ngecandelo elingundoqo lenkqubo yakho "eyalela ngokuchanekileyo kwaye ithembele kwicala". Silawula ngokungqongqo uMgangatho. Le modyuli iveliswe ngokusesikweni ngumenzi waseTshayina, kwaye iyunithi nganye iye yavavanywa kwisiza esisebenzayo ukuqinisekisa ukusebenza okuzinzileyo. Nje ukuba ufake iodolo, unokufumana iimpahla ngokukhawuleza ngaphandle kokulibazisa ukuveliswa kunye nokulungiswa kwendawo.

Iiparamitha zeMveliso

Ngaba akwanelanga ngophawu lokutshintsha nje?

Ukuthembela ngokulula kwisiginali yokutshintsha ukulawula imotor ihlala isilela ukuhlangabezana neemfuno zemveliso. Ulawulo oluchanekileyo lokuvula i-valve kunye nesantya semoto asinakufezekiswa ngaphandle kokutshintsha ngokuqhubekayo iimpawu zombane. Kwaye le Allen Bradley 1746-NO8V yenzelwe ngokuchanekileyo ukujongana nale ndawo yentlungu. NjengeFactory egxile kulawulo lwemizi-mveliso, sibazi kakuhle ubunzima kulawulo lwendawo. Le modyuli yenzelwe ngokukodwa inkqubo ye-SLC 500 kwaye ayifuni ukuguqulwa okuntsonkothileyo. Iyakwazi ukulungelelaniswa ngokuthe ngqo kwaye ibonelele ngokuthe ngqo izibonakaliso zombane eziqhubekayo kwiivalve kunye ne-actuators, ukwenza ummiselo uchaneke ngakumbi kwaye usebenze ngakumbi, ukusombulula ngokupheleleyo ingxaki yolawulo olubi ngeempawu zokutshintsha.

Ngaba umsebenzi uzinzile ngokwaneleyo?

Imodyuli ye-Allen Bradley 1746-NO8V inomsebenzi ogqwesileyo. Inoluhlu olubanzi lwemveliso kwaye inokufikelela ngokuqhelekileyo i-0-10 volt output output. Ikwaxhasa iindidi ezahlukeneyo zombane we-single-polarity kunye ne-bipolar, ezifanelekileyo kwiimfuno ezahlukeneyo zesayithi. Isisombululo sayo siphezulu kakhulu, siyakwazi ukwahlula amawaka amanqanaba ombane ahlukeneyo, ngokuchaneka okuphezulu kokulawula.

Eyona ngongoma ibalulekileyo kukuba inomthamo owomeleleyo womthwalo kunye nemveliso eyaneleyo yangoku. Nangona intambo edibanisa i-actuator ide, isignali ayiyi kuthotywa okanye igqwethwe, iqinisekisa ukuhanjiswa ngokuchanekileyo kwemiyalelo. Kwangaxeshanye, inesantya sokuphendula esikhawulezayo. Nje ukuba i-CPU ikhuphe umyalelo, imodyuli inokutshintsha ngoko nangoko i-voltage phantse kungabikho kulibaziseka, ilungelelanise ngokugqibeleleyo kwiimfuno zolawulo lweenkqubo zamashishini ezinamandla.

Zeziphi iimbalasane eziphambili?

Olona phawu lwahlukileyo lwe-Allen Bradley 1746-NO8V luyilo oluzimeleyo lwemveliso ye-8-channel. Imisebenzi ebikade ifuna iimodyuli ezinezitishi ezi-4 ngoku inokufezekiswa ngeyunithi enye. Kwiikhabhathi zombane ezindala esele zixinene, ngokungathandabuzekiyo oku kungummangaliso wokonga indawo. Ngaphandle kwesidingo sokwandisa ikhabhinethi, iziphumo zomqondiso ezininzi zinokufezekiswa.

Enye imbalasane ngumsebenzi wayo "wokugcinwa kwemveliso", esiyixabisa ngokukhethekileyo kwimisebenzi yethu ephathekayo - ukuba inkqubo ye-PLC ilahlekelwa ngamandla ngokukhawuleza okanye i-CPU iyeka ukusebenza, imodyuli iya kugcina ixabiso lokugqibela lombane okanye isebenze ngokwexabiso lokhuseleko olusethiweyo, ukuthintela zonke izixhobo kwisiza ukuba ziyeke ngokukhawuleza okanye ziqalise kakubi, ngokufanelekileyo ukuthintela iingozi zemveliso. NjengoMvelisi oqeqeshiweyo, sibonelela ngazo zonke iimveliso ezintsha kraca. Imbonakalo icocekile kwaye intsebenzo ilungile. Emva kokuba zifunyenwe, zinokufakelwa ngokuthe ngqo kwaye zisetyenziswe.

Kulula kangakanani ukufakela kunye nokusetyenziswa?

I-Allen Bradley 1746-NO8V ilula kakhulu ukuyifaka. Inokuthi ifakwe ngokuthe ngqo kuyo nayiphi na i-slot ye-1746 ye-SLC 500 system rack (ngaphandle kwe-slot 0). I-wiring isemgangathweni kwaye ihambelana nemigangatho yezoshishino. Iinjineli eziqheleneyo nolu luhlu lweenkqubo zinokugqiba ukufakela kunye nokulungiswa kweempazamo ngokukhawuleza. Kwangaxeshanye, siya kubonelela ngesikhokelo esilula socingo ukukunceda ukuba uqalise ngokukhawuleza.

Ukusetyenziswa kwansuku zonke akufuni ukulungiswa okuyinkimbinkimbi. Jonga nje iitheminali zocingo rhoqo kwaye ugweme ukukhulula. Ukongeza, imveliso inexabiso eliphezulu lokusebenza kwexabiso (Ixabiso kunye nexabiso eliphantsi). Siye sazicima iipremiyamu ezingeyomfuneko, sivumela wonke umntu ukuba afumane iimodyuli zomgangatho ophezulu we-analog voltage output ngexabiso elifanelekileyo kunye nokunciphisa iindleko zotyalo-mali lweprojekthi.
