Umxholo woMsebenzi weNtambo yeSikrufu yeSigodlo seNdabuko
Kwikhabhinethi yokulawula ye-PLC ephakathi nendawo yoomatshini bokupakisha, iinkqubo zokuhambisa, okanye ulawulo lomatshini wokubumba ngenaliti, ngokuqhelekileyo kukho iziphelo zentambo ezizi-600-1,200. Isiphelo ngasinye kwibhloko yesiphelo sesiqhelo se-screw-clamp feed-through sifuna: ukususa i-insulation ye-8-10mm ukusuka kwisiphelo sentambo kusetyenziswa isixhobo sokuqhawula esilinganisiweyo, ukufaka intambo ehlutshiweyo kwindawo yokuvula isiphelo, ukuqinisa i-screw kwi-torque echaziweyo (ngesiqhelo yi-0.5-0.8 Nm kwintambo ye-2.5mm² njengoko kuchaziwe ngumvelisi wesiphelo), kunye nokuqinisekisa uqhagamshelo ngovavanyo lokutsala ngokwe-IEC 60947-7-1. Umjikelo opheleleyo wokufaka i-strip-insert-tighten-verify uthatha imizuzwana engama-45-90 ngentambo nganye kuxhomekeke kumava ochwepheshe, ukufikelela kwindawo yesiphelo kwikhabhinethi exineneyo, kunye nokuba ukuhanjiswa kwentambo kufuna amanyathelo ongezelelweyo olawulo lwentambo. Ngomyinge wemizuzwana engama-60 ngoqhagamshelo kunye neziphelo ezingama-800 ngekhabhinethi nganye, umsebenzi wocingo oluthe ngqo kuphela yimizuzu engama-800 - ngaphezulu kweeyure ezili-13 ngekhabhinethi nganye.
Oku akubandakanyi ixesha elifunekayo ukutolika umzobo wocingo kunye nokuwudibanisa kwiindawo zesiphelo. Umzobo wocingo ubonisa uqhagamshelo olunengqiqo: "I0.0 → isiphelo X1:47." Ingcali kufuneka ifumane isiphelo X1 kwireyile ye-DIN, ibale ukuya kwindawo engama-47 kumqolo wee-terminals ezibonakala zifana ezingama-60-80, kwaye ifake ucingo oluchanekileyo. Kwi-density ye-terminals ezingama-60 ngemitha nganye yereyile ye-DIN, ucalucalulo olubonakalayo phakathi kwesiphelo 47 kunye nesiphelo 48 lufuna ingqwalasela egxile kuyo yonke inxibelelwano. Izinga lempazamo phantsi kweemeko zemveliso - apho iingcali zidibanisa iikhabhathi iiyure ezi-7-8 ngeshifti nganye - malunga neempazamo zocingo ezi-2-5 kwikhabhathi nganye ngokomndilili, ngokusekelwe kwidatha yomgangatho wevenkile yepaneli endiyijongileyo. Impazamo nganye ithatha imizuzu eli-15-45 ukuxilonga nokulungisa ngexesha lovavanyo olusebenzayo, yongeza imizuzu engama-30-225 yexesha lokuphinda usebenze kwikhabhathi nganye. Ezi mpazamo phantse zingumsebenzi wenyathelo lokubonisa ngesandla - iminwe yengcali ifike kwintambo echanekileyo kodwa indawo yesiphelo engalunganga - kwaye akunakwenzeka ukuba zisuswe ngoqeqesho okanye uqeqesho lwenkqubo kuphela.
I-Pluggable Paradigm: Iphela kwiHarness, Hayi kwiKhabhinethi
Iibhloko zesiphelo ezinokuxhunywa zitshintsha indlela esisiseko yokudibanisa intambo ukusuka ekupheliseni ikhabhinethi ukuya ekupheliseni kwi-harness. Endaweni yokuzisa iingcingo ngazinye kwikhabhinethi kwaye ziphelise nganye kwindawo yayo emiselweyo kwi-DIN rail, umakhi wephaneli ufumana ii-harnesses zentambo ezihlanganisiweyo kwangaphambili ezinezihlanganisi ezinokuxhunywa esele zipheliseni kwisiphelo sentambo. Ibhloko yesihlanganisi - iplagi yesikhundla se-2-24 ene-pitch ye-5.08mm - idibana ne-header esisigxina efakwe kwi-DIN rail. Umsebenzi womakhi wekhabhinethi utshintsha ukusuka kwii-800 zokuphelisa iingcingo ngazinye ukuya ekupheliseni ii-20-40 zokudibanisa ezihlanganisiweyo kwi-headers zazo ezifanelekileyo.
Le yimodeli yokuhlanganisa eyahlukileyo ngokusisiseko eneziphumo ezidlula kude imali eyongiweyo ngqo kubasebenzi. Umsebenzi wocingo oluchanekileyo noluneziphene utshintshelwa phezulu ukuya kwinqanaba lokuvelisa i-harness, apho unokwenziwa ebhentshini phantsi kweemeko zokukhanya ezingcono, ngokufikelela okungenakuthintelwa kwiindawo zokudibanisa, kwaye - ngokubalulekileyo - ngezixhobo zokuvavanya i-harness ezizenzekelayo eziqinisekisa lonke uqhagamshelo lokuqhubeka, ukunikezelwa kwephini ngokuchanekileyo, kunye nokumelana nobushushu ngaphambi kokuba i-harness ithunyelwe kwi-panel shop. Inkqubo yovavanyo lwe-harness esebenzisa i-Cirris okanye umvavanyi ofanayo ozenzekelayo inokuqinisekisa i-connector assembly ye-50-position kwimizuzwana engaphantsi kwama-30 kwaye ivelise ingxelo yovavanyo esebenza njengobungqina bomgangatho ochanekileyo kuhlolo oluzayo lwe-panel shop. Utshintsho luvela ekuthembeni ingqalelo yengcali ukuya ekuthembeni umlinganiselo ochanekileyo wezixhobo zokuvavanya.
Ukonga ixesha kukhulu kwaye kubhalwe kakuhle kwisakhiwo seephaneli zemizi-mveliso. Ibhloko yokudibanisa enezintambo ezili-12 eziphelisiweyo ngaphambili ixhuma kwi-DIN rail header yayo kwimizuzwana emi-5-10 - ixesha elifunekayo ukulungelelanisa isixhumi ne-header, ukuyityhala ide ithebhu yokutshixa idibane ngokucofa okuvakalayo, kwaye uqinisekise ngokubonakalayo ukufakwa ngokupheleleyo ngokujonga ukuba ubuso besixhumi buchanekile nobuso be-header. Ibhloko yesiphelo sesikrufu yendabuko enezikhundla ezili-12 ifuna imizuzu eli-12-18 ukuba iphele kwikhabhinethi. Indlela yokuxhuzula inciphisa oku ukuya ngaphantsi kwemizuzwana engama-30 yokusebenza kwicala lekhabhinethi - ukuncipha okungaphezulu kwama-95% kumsebenzi wecala lekhabhinethi kwezo qhagamshelo zili-12. Kwikhabhinethi yoqhagamshelo ezingama-800 eneziqhagamshelo ezinokuxhuzulwa, ixesha loqhagamshelo lwekhabhinethi lehla ukusuka kwiiyure ezili-13 nangaphezulu ukuya kwiiyure ezi-2-3. Ixesha lokuhlanganisa i-harness ephelisiweyo, elenziwa ebhentshini, longeza iiyure ezi-4-6, ukuze kuncitshiswe i-35-45% kumsebenzi we-wire iyonke.
Ukususwa kweMpazamo ngePinout eQinisekisiweyo
Eyona nzuzo ibalulekileyo ngokwezoqoqosho yeebhloko zesiphelo ezinokuxhunywa isenokungabi kukonga kwabasebenzi — kukushenxiswa phantse kweempazamo zokwabiwa kwentambo. Xa umenzi wehashe esakha isixhumi esineendawo ezili-12 esineentambo kwiindawo eziqala kwi-1 ukuya kwi-12, i-pinout ilungisiwe ngokwasemzimbeni. Umakhi wephaneli akanakufaka intambo engalunganga kwindawo yesi-7 kuba intambo yendawo yesi-7 sele iphelile kwisixhumi kwindawo yesi-7 kwaye ayinakushukunyiswa ngaphandle kokuyisika nokuyiphelisa kwakhona. Isenzo sokudibanisa kuphela kwikhabhinethi kukufaka isixhumi kwintloko echanekileyo, ebhalwe ngesazisi sesixhumi (umz., "X101") esihambelana nomzobo wocingo kunye nelebheli ebonakalayo emzimbeni wesixhumi esisecaleni sehashe.
Olu tshintsho ukusuka ekuqinisekisweni ngentambo nganye ukuya ekuqinisekisweni ngekhonkco ngalinye lutshintsha ngokusisiseko iprofayili yokubhaqwa kwempazamo. Kwikhabhinethi yesiqhelo eneentambo ezisuka kwindawo enye ukuya kwenye, zonke iintambo ezingama-800 kufuneka zihlolwe ngokwahlukeneyo ngokubhekiselele kumzobo wentambo - inkqubo yokuqinisekisa efuna iiyure ezi-4-6 kwaye ixhomekeke kwisantya esifanayo sempazamo yomntu njengentambo yokuqala. Ngezixhumi ezixhunywayo, ukuqinisekiswa kunciphisa ukuya kuthi ga: (1) ukuqinisekisa ukuba intambo yayiqhubeka kwaye i-pinout ivavanyiwe kumenzi we-harness kwaye ingxelo yovavanyo iyafumaneka, kunye (2) ukuqinisekisa ukuba iplagi nganye yesixhumi ikwintloko echanekileyo ngokujonga ngokubonakalayo ilebhile ngokubhekiselele kumzobo woyilo lwekhabhinethi. Inyathelo lesi-2 lithatha imizuzu eli-10-15 kwizixhumi ezingama-30. Umsebenzi wokuqinisekisa uwonke uyehla ukusuka kwiiyure ezi-4-6 ukuya ngaphantsi kweyure. Izinga lempazamo yentambo liyehla ukusuka kwi-2-5 kwikhabhinethi nganye ukuya kufutshane ne-zero kuba i-pinout inyanzeliswa ngokoqobo sisixhumi - akukho sigqibo somsebenzi malunga nokuba yeyiphi intambo eya apho, kuphela kukudibana okubonakalayo phakathi kweelebhile ezimbini.
I I-UL 508A umgangatho weephaneli zolawulo zemizi-mveliso kunye I-IEC 61439 Kwizixhobo zokudibanisa i-switchgear kunye ne-controlgear, zombini ezi zixhobo zibhekisa kwiteknoloji yoqhagamshelo oluxhunywayo njengendlela yokuphucula umgangatho wocingo lwefektri. I-UL 508A ivumela ngokukodwa izihlanganisi ezixhunywayo njengendlela yoqhagamshelo eyamkelekileyo xa nje isihlanganisi sidweliswe kwisicelo kwaye ukulinganiswa kwe-voltage/current kungaphakathi kweenkcukacha zomenzi wesihlanganisi.
Inkonzo yasentsimini: Apho i-ROI iyanda khona
Ukonga ixesha lokuhlanganisa kuthetha ukwamkelwa kweebhloko zesiphelo ezinokuxhunywa kwivenkile yeepaneli; ukonga kwinkonzo yasentsimini kulapho i-ROI ikhawuleza khona ngaphaya kwesizathu sokuqala sokuthenga. Xa imodyuli ye-I/O ingaphumeleli kwikhabhinethi ye-PLC enxibe ii-terminals zesikrufu zendabuko, inkqubo yenkonzo yasentsimini ithatha ixesha elininzi: thatha iifoto okanye ubhale ilebheli kuyo yonke intambo eqhagamshelwe kwimodyuli engaphumeleliyo (imizuzu eli-10-30, kuxhomekeke kubuninzi bentambo kunye nomgangatho weelebheli okhoyo), khupha zonke iingcingo ezingama-20-40 (imizuzu emi-5-15), susa imodyuli engaphumeleliyo kwaye ufake enye endaweni yayo (imizuzu emi-5-10), phinda ucime zonke iingcingo kwiiterminals ezichanekileyo kwimodyuli yokutshintsha ngelixa ubhekisa kwifoto okanye iilebheli ezithathwe kwinyathelo loku-1 (imizuzu engama-20-45), kwaye uqinisekise lonke uqhagamshelo (imizuzu emi-5-10). Ixesha elipheleleyo elidlulileyo: imizuzu engama-45-105 yomsebenzi wobuchwephesha onobuchule, apho umatshini wokuvelisa ungasebenzi.
Ngezixhumi ezinokuxhunywa, inkqubo iyawa ukuze: ikhuphe ibhloko yesixhumi kwimodyuli engaphumelelanga (imizuzwana emi-5), isuse imodyuli engaphumelelanga kwaye ifake enye endaweni yayo (imizuzu emi-5-10), kwaye ifake ibhloko yesixhumi kwimodyuli yokutshintsha (imizuzwana emi-5). Iingcingo ezingenanto azixhunywanga. Iingcingo ezingenanto ziyacinywa kwakhona. Uqhagamshelo olungenanto lufuna ukuqinisekiswa kuba isixhumi esifanayo esineengcingo ezifanayo kwiindawo ezifanayo zephini ngoku sixhunyiwe kwimodyuli yokutshintsha efanayo. Ixesha lilonke - ngaphantsi kwemizuzu eli-10, elilawulwa kukutshintshwa kwemodyuli yoomatshini kunye nokuqaliswa kwakhona kwe-PLC - linciphiso lwama-80-90% kwinkqubo yesiqhelo. Kumashishini apho ixesha lokungasebenzi komatshini lixabisa i-USD 500-5,000 ngeyure (imigca yokuhlanganisa iimoto, ukupakishwa kokutya neziselo, ukwenziwa kwamayeza, ukwenziwa kwe-semiconductor), umahluko phakathi kokulungiswa kwemizuzu engama-90 kunye nokulungiswa kwemizuzu eli-10 kusindisa i-USD 650-7,500 kwixabiso lexesha lokungasebenzi ngemodyuli nganye ye-I/O. Kwiminyaka eli-10-15 yokusebenza komatshini kunye nokutshintshwa kweemodyuli ze-I/O ezi-3-6, ukonga kwenkonzo yasentsimini kuphela kunokudlula iindleko ezongezelelekileyo zeebhloko zesiphelo ezinokutsalwa nge-3-5x.
Uqoqosho lweendleko zoQhagamshelo ngoQhagamshelo
Kwinqanaba lecandelo, ibhloko yesiphelo yesiqhelo yeendawo ezimbini ene-screw-clamp feed-through ixabisa malunga ne-USD 0.30-0.60 kwindawo nganye ngobuninzi bomthamo (izikhundla ezingaphezu kwe-5,000). Inkqubo yebhloko yesiphelo ye-5.08mm enokuxhunywa - equka i-DIN rail-mounted header kunye ne-harness-side plug connector - ixabisa malunga ne-USD 0.80-1.50 kwindawo nganye. Iprimiyamu yeendleko zecandelo yi-USD 0.50-1.00 enentsingiselo kwindawo nganye, ethi kwikhabhinethi eneendawo ezingama-800 imele i-USD 400-800 kwixabiso elongezelelweyo lezinto zokwakha.
Nangona kunjalo, iindleko zecandelo ziyinto enye kuphela. Izinga labasebenzi bendibano eligcwele umthwalo kwivenkile yepaneli eMntla Melika okanye eNtshona Yurophu yi-USD 35-55 ngeyure. Ukonga kwabasebenzi ngoqhagamshelo ngalunye — malunga nemizuzwana engama-30-50 — kuthetha ukuba yi-USD 0.29-0.76 ngoqhagamshelo ngalunye kwezi xabiso. Ukusebenzisa iindawo eziphakathi zoluhlu ngalunye, iprimiyamu yecandelo le-USD 0.75 ihlawulelwa yi-USD 0.50 kwimali yogcino lwabasebenzi, ishiya iprimiyamu epheleleyo ye-USD 0.25 ngesikhundla ngasinye — okanye i-USD 200 kwikhabhinethi eneendawo ezingama-800. Xa ukonga inkonzo yasentsimini, ixesha lovavanyo olusebenzayo elincitshisiweyo, kunye nokususwa kwamabango eentambo zewaranti kufakiwe, iindleko zizonke zobunini zitshintsha ngokungqongqo zikhetha izihlanganisi ezinokuxhunywa kunyaka woku-1-2 wokusebenza kwentsimi.
Imibuzo ebuzwa qho
Ithini ireyithingi yangoku yeebhloko zesiphelo ezinokuxhunywa ze-5.08mm?
Iibhloko zesiphelo ezisetyenziswayo ezixhunywayo zepitch eziyi-5.08mm zilinganiswe nge-12-16A kwi-300V ngokwemigangatho ye-IEC 61984 kunye ne-UL 1059, kusetyenziswa intambo eyi-0.5-2.5mm² (20-14 AWG). Oku kugubungela uninzi lweempawu ze-PLC I/O — ii-digital inputs (5-15mA kwi-24VDC), iziphumo zedijithali (0.5-2A kwi-24VDC okanye kwi-120VAC), kunye nezibonakaliso ze-analog (4-20mA okanye kwi-0-10V). Uqhagamshelo lwamandla aphezulu olufana nee-motor contactors, izixhobo zamandla, kunye neesekethe ze-heater ezingaphezulu kwe-16A kufuneka zisebenzise izihlanganisi ezinkulu (7.5mm okanye 10.16mm) okanye iibhloko zesiphelo samandla sendabuko. Umgangatho wepitch we-5.08mm wenzelwe ngokukodwa ukuhambelana nesithuba se-terminal kwiimodyuli ze-PLC I/O ezivela kubavelisi abakhulu kuquka i-Siemens S7, i-Allen-Bradley ControlLogix, kunye ne-Mitsubishi MELSEC series, nto leyo eyenza ukuba ibe ngumgangatho ofanelekileyo wocingo lwe-PLC cabinet I/O kwihlabathi liphela.
Zisebenza njani iibhloko zesiphelo ezinokutsalwa phantsi kweemeko zokungcangcazela kwemizi-mveliso?
Xa ichazwe ngokufanelekileyo nge-latch edibeneyo yokutshixa, izihlanganisi ezinokuxhunywa zisebenza ngokuthembekileyo phantsi kweemeko eziqhelekileyo zokungcangcazela kwemizi-mveliso. Ingcaciso ephambili yindlela yokugcina isihlanganisi — khangela izihlanganisi ezine-latch evalayo enika ukucofa okuvakalayo xa kufakwe ngokupheleleyo, endaweni yokugcina ukulingana nokungqubana. Uthotho lwe-PCT luka-J-Guang lusebenzisa uyilo lwe-latch ezimbini olunamandla okugcina adlula i-80N, oluvavanyiweyo I-IEC 60068-2-6 Uvavanyo lokungcangcazela kwi-10-500 Hz kunye ne-amplitude yokufuduka ye-0.35mm. Kwiimeko ezigqithisileyo zokungcangcazela ezifana nezixhobo zemigodi, amagumbi eenjini zaselwandle, kunye nesitokhwe sokuqengqeleka sikaloliwe, izihlanganisi ze-screw-flange ezine-mechanical screw-down retention kwi-header zibonelela ngokhuseleko olongezelelweyo ngaphaya kwe-locking latch eqhelekileyo. Kwiminyaka eli-14 yedatha yentsimi kwisiseko sethu esifakiweyo, asikaze sibhale ukusilela kwentsimi okubangelwa kukwahlulwa kwesihlanganisi phantsi kweemeko zokusebenza eziqhelekileyo zoshishino xa imodeli ye-locking latch yayichazwe kwaye yafakwa ngokuchanekileyo.
Ingakanani i-odolo encinci yokulungiselela uqwalaselo lwesixhumi esenziwe ngokwezifiso?
Izihlanganisi eziqhelekileyo ezikwaziyo ukuxhunywa kwindawo ezi-2-24 ezine-pitch ye-5.08mm ziyafumaneka kwisitokhwe ngaphandle kobungakanani obuncinci be-odolo — iiyunithi ezi-1 zinoku-odolwa ukuze kwenziwe i-prototyping kunye novavanyo lwe-pilot. Uqwalaselo olwenziwe ngokwezifiso oluneendibaniselwano ezithile zokubala iiphini, ikhowudi yombala ngokwemisebenzi (umz., oluhlaza okwesibhakabhaka kwiimpawu ze-DC, obomvu kwi-AC, otyheli kwiisekethe zokhuseleko), okanye iilebhile zokuchonga izihlanganisi eziprintiweyo kwangaphambili zihlala ziphethe ii-MOQs zeziqwenga ezingama-500-1,000 kunye namaxesha okukhokela eeveki ezi-4-6. Kwii-OEMs ezilungelelanisiweyo kuqwalaselo oluthile lwesihlanganisi kumgca wonke wemveliso, iindleko zezixhobo zokuhlanganisa ezenziwe ngokwezifiso zihlala zihlawulwe kwiikhabhinethi zokuqala ezingama-500-1,000, kwaye ukuhambelana kweelebhile kuzo zonke iikhabhinethi ezikwintsimi kwenza kube lula kakhulu uxwebhu lwenkonzo yasentsimini kunye nolawulo lweendawo ezisele.
Ngaba iikhabhathi ezikhoyo ezinezikrufu-isiphelo sendlela zinokufakelwa kwakhona ngezihlanganisi ezixhunywayo?
Ukulungiswa okungaphelelanga kunokwenzeka kodwa kufuna uvavanyo lobunjineli. Ukuba ikhabhinethi ekhoyo isebenzisa ukufakwa kwe-DIN rail standard, ii-pluggable terminal block headers zinokufakelwa kwi-rail efanayo. Nangona kunjalo, iintambo ezikhoyo kuya kufuneka ziphinde zipheliswe ngee-plugs ze-pluggable connector - nto leyo ethetha ukuphinda ifake i-cabinet. Ukulungiswa kwakhona kuluncedo kakhulu xa ikhabhinethi sele icwangciselwe ukufakelwa i-rewire enkulu (umz., ngexesha lokuphuculwa kwenkqubo yolawulo ukusuka kwisizukulwana esidala se-PLC). Kwikhabhinethi entsha yokwakha, indlela ye-wiring harness echazwe apha ngasentla inika iingenelo ezipheleleyo. Kwiikhabhinethi ezikhoyo, ixabiso elinyukayo lokulungiswa kwakhona ngokuyintloko kukonga ixesha lenkonzo yasentsimini xa iimodyuli ze-I/O zifuna ukutshintshwa, kuba umsebenzi wokuqala wokufakelwa kwentambo sele wenziwe. Sicebisa ukuvavanya ukutshintshwa kwe-retrofit kwisiseko sekhabhinethi ngekhabhinethi ngokusekelwe kubomi benkonzo eseleyo elindelekileyo kunye nezinga lokusilela kwe-I/O module yembali kuloo modeli yezixhobo ezithile.
