IiBhloko zesiphelo ezinokuxhunywa vs iiBhloko eziFixed: Ixesha lokukhetha ukuCima ngokukhawuleza kwiiNkqubo zeModular
💡 TL;DR
- Iibhloko zesiphelo ezifakelwayo zivumela ukutshintshana kweemodyuli ngaphantsi kwemizuzwana engama-30, xa kuthelekiswa nemizuzu emi-5-15 kwiibhloko ezisisigxina — ukuncipha kwe-90%+ kwixesha lokungasebenzi kwenkonzo.
- Uyilo olunokutsalwa luxabisa ngaphezulu ngama-25-40% ngesikhundla ngasinye kwangaphambili, kodwa lunciphisa iindleko zizonke zobunini nge-15-30% kwiinkqubo ezifuna imicimbi yolondolozo emithathu nangaphezulu ngonyaka.
- Ipitshi ye-3.81mm yeyona ndlela iqhelekileyo kwiibhloko ezixhunywayo kwimizi-mveliso (ezigubungela malunga ne-35% yezicelo), ngelixa ipitshi ye-7.62mm iphatha ukusasazwa kwamandla ukuya kuthi ga kwi-20A.
- Iibhloko ezixhunywayo zespring-clamp zihambelana kakuhle neenkqubo ze-modular I/O, ngelixa iibhloko ezizinzileyo zescrew-clamp zihlala zilawula iisekethe zamandla ezinamandla aphezulu ngaphezu kwe-41A.
- Kwii-OEM ezivelisa iinkqubo zolawulo lwemodyuli, ukutshintshela kwizihlanganisi ezinokuxhunywa kuzo zonke iisekethe zesignali kunye namandla aphantsi kunokunciphisa ukubuya kokusilela kwentsimi malunga ne-22% ngenxa yeempazamo ezimbalwa zocingo ngexesha lokulungiswa.
Iibhloko zesiphelo ezinokuxhunywa zivumela ukuqhawuka ngokupheleleyo kwentambo kwicala lesixhobo kwisithuba esingaphantsi kwemizuzwana engama-30 ngaphandle kokususa intambo enye, ngelixa iibhloko zesiphelo ezisisigxina zifuna ukucinywa ngokupheleleyo ngalo lonke ixesha imodyuli ifuna ukulungiswa - umahluko odibanisa iiyure zomsebenzi ogciniweyo kubomi bonke benkqubo yesiphelo.
Ukukhetha phakathi kweebhloko zesiphelo ezinokutsalwa kunye nezizinzileyo akuyonto yokuba yeyiphi "engcono." Lurhwebo phakathi kweendleko zecandelo elingaphambili kunye nokusebenza kakuhle kwexesha elide, kwaye impendulo echanekileyo ixhomekeke ngokupheleleyo ekubeni inkqubo yakho iya kulungiselelwa kangaphi, iphuculwe, okanye ilungiswe kwakhona. Nantsi isakhelo esixhaswa yidatha sokwenza eso sigqibo.
Yintoni kanye kanye i-Pluggable Terminal Block?
Ibhloko yesiphelo esixhunywayo yinkqubo yesixhumi esineziqwenga ezibini equlathe i-header esisigxina (efakwe kwi-DIN rail okanye kwi-PCB) kunye neplagi esuswayo ethwala iingcingo eziphelileyo, evumela ukuba uqhagamshelo lombane luqhekeke kwaye lwenziwe kwakhona ngaphandle kokuphazamisa iingcingo kumacala omabini.
Icala lentloko lifakelwe ngokusisigxina — nokuba lifakwe kwi-PCB okanye lifakwe kwi-DIN rail. Icala leplagi lifumana iingcingo zentsimi kwaye lingafakwa okanye lisuswe kwi-header ngesandla. Akukho zixhobo zifunekayo, akukho kukhululeka kwezikrufu, akukho kukhutshelwa kwakhona kweengcingo. Le yeyona nzuzo iphambili eqhuba umkhwa wenkqubo yemodyuli kwi-automation yemizi-mveliso.
Ngoku ka I-IEC 60947-7-1 udidi, iibhloko zesiphelo ezinokuxhunywa ziwela phantsi kodidi "lwe-plug-in", ekufuneka lubonise ubuncinane imijikelo engama-50 yokufakwa/yokukhupha ngaphandle kokonakala kokumelana noqhagamshelwano.
IiPluggable Terminal Blocks Ziyaphumelela Nini?
Iibhloko zesiphelo ezixhunywayo zibonelela ngembuyekezo elinganisekayo kutyalo-mali xa inkqubo yakho ifumana iziganeko zokulungisa okanye zokuphucula ezi-3 nangaphezulu ngonyaka, okanye xa iindleko ixesha lokungasebenzi kwemveliso lidlulile malunga ne-$50 ngomzuzu.

| I-Factor | Iibhloko zeTerminal eziQinisekisiweyo | Iibhloko zeTerminal ezinokuxhunywa |
|---|---|---|
| Ixabiso lesixhumi ngasinye (indawo ezi-2, iphimbo eliyi-5.08mm) | $0.35 – $0.55 | $0.50 – $0.80 |
| Lixesha lokuba nqamula kwaye uqhagamshele kwakhona imodyuli | Imizuzu emi-5–15 | Imizuzwana eli-15–30 |
| Umngcipheko wempazamo yocingo ngexesha lokuxhuma kwakhona | Okuphakathi (kufuneka ukufakelwa kwakhona intambo) | Iphantsi kakhulu (ulungelelwaniso lweplagi lufakwe izitshixo) |

Nantsi indlela yokubala i-rough break-even: ukuba ibhloko yakho esisigxina ixabisa i-$0.45 ngesikhundla ngasinye kwaye i-pluggable equivalent ixabisa i-$0.65, iprimiyamu ye-$0.20 ngesikhundla ngasinye ifunyanwa emva kweziganeko zenkonzo ezimalunga nezimbini - xa kucingelwa ukuba imizuzu eli-10 egciniweyo ngesiganeko ngasinye ngesantya somsebenzi esinzima se-$60/iyure ($10 ngesiganeko ngasinye esigciniweyo). Emva kwesiganeko senkonzo sesithathu, uphambili.
I-plugable vs Fixed: Uthelekiso loBugcisa oluneMilinganiselo emihlanu
Xa kuthelekiswa iibhloko zesiphelo ezinokutsalwa kunye nezizinzileyo kwiimilinganiselo ezintlanu ezinokulinganiswa — ixabiso, isantya, ukuthembeka, ukuphathwa kwangoku, kunye nomjikelo wobomi — uyilo olutsalwa luphumelela ngokufanelekileyo kwiindidi ezintathu ngelixa iibhloko ezizinzileyo zigcina iingenelo ezimbini.
| Ubukhulu | Ibhloko yesiphelo sendlela enokuxhunywa | Ibhloko yesiphelo esizinzileyo | Ophumeleleyo |
|---|---|---|---|
| 1. Isantya soQhagamshelo (ngentambo nganye) | Imizuzwana eli-10–15 (ucingo oluya kwiplagi) | Imizuzwana eyi-8–12 (ucingo oluya kwibhloko) | Izinzile (emaphethelweni) |
| 2. Ixesha lokutshintsha iiModyuli | Imizuzwana eli-15–30 | Imizuzu emi-5–15 | Iyaxhunywa |
| 3. Uzinzo lokumelana noqhagamshelwano | Ilungisiwe | ||
| 4. Ubuninzi boMbane wangoku | Ukuya kuthi ga kwi-41A (6mm², 7.62mm pitch) | Ukuya kuthi ga kwi-232A (95mm²) | Ilungisiwe |
| 5. Iindleko zoMjikelo woBomi (iminyaka emi-5, iinkonzo ezi-4/ngonyaka) | $15–$25 kwimodyuli nganye enezikhundla ezingama-24 | $35–$60 kwimodyuli nganye enezikhundla ezingama-24 | Iyaxhunywa |
Ukumelana noqhagamshelwano kwebhloko yesiphelo se-plugable terminal kuqala ngaphezulu kunebhloko esisigxina kuba lonke uqhagamshelo olunokuxhunywa luquka ujongano olongezelelweyo oludibeneyo phakathi kwe-plug contact kunye ne-header pin. Nangona kunjalo, kwiisekethe zenqanaba lesiginali (24V DC, ii-loops ze-4-20 mA, i-I/O yedijithali), lo mahluko wokuxhathisa awunakubalwa ngombane — ngesiqhelo ungaphantsi kwe-0.1% ye-voltage drop.
Imigangatho yePitch: Indlela yokukhetha ubungakanani obufanelekileyo
I-pitch ngumgama ophakathi ukuya embindini phakathi kweendawo ze-pin ezikufutshane, kwaye imisela umlinganiselo we-voltage, umthamo wangoku, kunye ne-wire gauge enokwamkelwa yi-pluggable terminal block.
| Iphimbo (mm) | Uvavanyo lweVoltage | Uvavanyo lwangoku | Ubungakanani beWire obuphezulu | Isicelo esiqhelekileyo |
|---|---|---|---|---|
| 3.50 mm | 150V | 8 A | 1.5 mm² (AWG 16) | Isignali, intambo yesenzi |
| 3.81 mm | 160V | 8 A | 1.5 mm² (AWG 16) | Uqhagamshelo lwe-PLC I/O, i-fieldbus |
| 5.00 mm | 300V | 10 A | 2.5 mm² (AWG 14) | Ulawulo oluqhelekileyo lwenjongo |
| 5.08 mm | 300V | 10 A | 2.5 mm² (AWG 14) | Injongo ngokubanzi (umgangatho waseMntla Melika) |
| 7.50 mm | 600V | 20 A | 4 mm² (AWG 12) | Umbane, iimoto eziqhubayo |
| 7.62 mm | 600V | 20 A | 6 mm² (AWG 10) | Ukusasazwa kwamandla, i-voltage ephezulu |
Ukusetyenziswa kweNkqubo yeModular: Umzekelo weHlabathi lokwenyani
Cinga ngomatshini wokupakisha i-OEM evelisa iikhabhathi zokulawula ezizimodyuli ezineemodyuli ezine zombane, iimodyuli ze-I/O ezisi-8, kunye neemodyuli zokulawula intshukumo ezi-2, nganye ifuna ukutshintshwa rhoqo ngexesha lemijikelo yokutshintsha izixhobo zomatshini.
Ngeebhloko zesiphelo ezizinzileyo, ukutshintsha imodyuli enye ye-I/O engasebenziyo kufuna ukuba ingcali ilebhelishe kwaye isuse iingcingo ezili-16 kwimodyuli endala, ihlube kwakhona kwaye igqibe kwakhona intambo nganye kwimodyuli entsha, iqinisekise indawo eyiyo ngokuchasene nomzobo wocingo (ngesiqhelo imizuzu engama-20 yokujonga), kwaye ivavanye ukuqhubeka kwayo yonke inxibelelwano. Ixesha lilonke: imizuzu eli-18–25 kwimodyuli nganye.
Nge iibhloko zesiphelo ezinokutsalwa, ingcali ikhupha iplagi eneendawo ezili-16 kwimodyuli ye-I/O engasebenziyo, iyifake kwimodyuli yokutshintsha, ize iyifake kwi-DIN rail header. Ixesha lilonke: imizuzu emi-2–4 kwimodyuli nganye. Kumjikelo wokutshintsha weemodyuli ezisi-8, oko kuthetha ukuba kugcinwe iiyure ezi-2.5 zomsebenzi.
Kwiminyaka esi-7 yobomi bomatshini obuqhelekileyo kunye neziganeko ezimbini zokulungisa izixhobo ngonyaka, uyilo olunokutsalwa lugcina malunga neeyure ezingama-560 zomsebenzi wobuchwephesha. Ngexabiso eliphantsi le-$60/iyure, oko kuthetha ukuba yi-$33,600 yokonga ubomi bonke — idlula kakhulu iindleko ezongezelelweyo zecandelo ezimalunga ne-$320 kwizihlanganisi ezinokutsalwa kulo lonke ikhabhinethi.
