Indlela Ukwakhiwa Kwezakhiwo Ezinezitezi Ezintathu Okuxazulula Ngayo Inkinga Yokuvinjelwa Kwesikhala

Ubuchwepheshe Bokusebenza Ngogesi Bokumisa Ama-Triple-Deck

Ibhulokhi yesiphelo enamadekhi amathathu inamazinga amathathu azimele okuphela kukagesi—phezulu, phakathi, naphansi—ahlanganiswe ngaphakathi kweyunithi eyodwa yendlu efakwa ku-DIN rail ejwayelekile (35mm EN 60715). Idekhi ngayinye ihlukaniswe ngogesi kodwa ihlanganyela indlu efanayo yemishini.

Ngoba Idekhi ngayinye isebenza njengendawo yayo yokuphela yomqhubi ezimele, ukwakheka kwedekhi elithathu kwenza imisebenzi emithathu kagesi ehlukene esikhaleni sobubanzi beyunithi eyodwa:

• Idekhi 1 (Phezulu): Ukufakwa kwesignali ye-Field I/O—kuxhuma i-sensor engenayo noma i-actuator wire
• Idekhi 2 (Ephakathi): Ibhasi lokuxhumanisa elihambayo—lisabalalisa isignali ezindleleni eziningi zokukhipha ngaphakathi kwebhulokhi
• Idekhi 3 (Ngezansi): Isiteshi sokufaka se-PLC noma indawo yokubhekisela—ixhuma esiteshini sokuya kuso

Ekhabhinethini evamile esebenzisa amabhlogo asezingeni elilodwa, ukusabalalisa isignali eyodwa ye-analog eziteshini ezintathu zokufaka ze-PLC kudinga amabhlogo amathathu ahlukene anama-wire jumpers angaphandle. Ngebhlogo eliyi-triple-deck, konke ukuxhumana okuthathu kungaphakathi kweyunithi efanayo ebonakalayo.

Ngokuvumelana ne Imibhalo yomkhiqizo we-WAGO's triple-deck terminal block, lo mklamo wokufaka izintambo zangaphakathi ususa kufikela ku-67% wezintambo zangaphandle eziwelanayo uma kuqhathaniswa nokulungiselelwa okufanayo kwebhulokhi yezinga elilodwa. Kwiphaneli eneziteshi zesignali ze-analog ezingama-50, lokho kungasho ukuthi izintambo zisebenza ngaphansi kwe-100+.

Ukwabelana Kwamanje kanye Nokuhlukaniswa Kwe-Thermal Ekulungiselelweni Okuhlanganisiwe

Ngoba Izindawo ezintathu zokuxhuma zigxile endlini eyodwa, ukushabalaliswa kokushisa ngevolumu yeyunithi ngayinye kuphakeme kunakumabhulokhi asezingeni elilodwa. Ngokwe-IEC 60947-7-1 kanye nama-curve okukhipha umkhiqizi:

• Uma amazinga okushisa emvelo engaphezu kuka-40°C, sebenzisa i-10-15% ye-derating factor
• Uma amazinga okugcwaliswa kwesitimela se-DIN engaphezu kuka-80%, sebenzisa enye into yokwehlisa u-5-10%

Kwibhulokhi yesiphelo se-J-Guang 301-5.0 PCB (umthamo wamanje olinganiselwe ngu-16A, izinga lokushisa lokusebenza -40°C kuya ku-+120°C), umthamo wamanje osebenzayo olungiselelweni lwe-triple-deck ku-45°C ambient kanye nokugcwaliswa kwesitimela okungu-90% cishe u-11-12A. Lokhu kusanele ezinhlelweni eziningi zesignali ye-analog ye-PLC (ngokuvamile i-4-20mA noma i-0-10V), kodwa kuqinisekisa ukuthi amabhlogo e-triple-deck kumele akhethwe ngokucophelela ukuze asebenzise amandla omthwalo wangempela, hhayi amandla omthamo olinganiselwe kukhathalogi.

Amasu Okuxhumana Okuphambene Kokusabalalisa Isignali ye-PLC: Umhlahlandlela Wobuchwepheshe

Ukuxhumana okuphambene ngogesi kuhlanganisa izigxobo eziningi zebhulokhi yesiphelo ukudala ibhasi elivamile lokusabalalisa isignali. Ngoba ithatha indawo yokuxhuma izintambo eziningi ngazinye ngendlela eyodwa yokuxhuma yangaphakathi, ukuxhumanisa okuphambene kuyindlela eyinhloko lapho amabhlogo okugcina aphezulu eletha khona ukusebenza kahle kwesikhala sawo.

Kuzinhlelo ze-analog ze-PLC I/O, ukuxhumana okuxhumene kuvame ukuvela ngezindlela ezintathu:

1. Ukwakhiwa Kwebhasi Lesignali: Umphumela wokudlulisela insimu eyodwa uxhumeke kuziteshi eziningi zokufaka ze-PLC ukuze kube nomqondo ophindaphindayo noma wokuvota.
2. Ukusatshalaliswa Kwendawo Evamile: Isiteshi sebhasi elilodwa elimisayo sixhuma kuzo zonke izindawo zokubhekisela zesignali ngebhasi langaphakathi elihlanganyelwe, sisuse "i-ground loop spaghetti."
3. Ibhasi Le-Voltage Elibhekiselwe: Kumasistimu esignali angu-0-10V, umthombo owodwa we-voltage yokubhekisela uxhuma eziteshini eziningi zokufaka ngedekhi eliphakathi.

Ngokombono wokuxazulula izinkinga, ukwakheka kokuxhumana okuhlanzekile kakhulu yilapho yonke indawo yokuhlangana ifinyeleleka futhi ilebula. Amabhulokhi anamadekhi amathathu anokuxhumana kwangaphakathi okuwelayo enza yonke indawo yokuhlangana ibonakale ezingeni lebhulokhi yesiphelo—inzuzo ebalulekile yokuqalisa nokusebenza kahle.

Ngokweqiniso, ukwakheka kokuxhumanisa kulapho ngibona khona ukwahlulela kobunjiniyela okukhulu. Iphutha elivamile ukuxhumanisa ngokweqile—ukudala amabhasi asebenza kahle ngogesi kodwa angafinyeleleki ngokomzimba ukuze alungiswe. Umthetho wami oyinhloko: uma ungakwazi ukufinyelela idekhi eliphakathi ngaphandle kokususa ibhulokhi eliseduze, ukwakheka kwebhasi lakho lokuxhumanisa kuyinkimbinkimbi kakhulu ukuba ingasetshenziswa ensimini.

Ukuqonda Imininingwane Yesikulufo Sesiphetho Sesikulufo Se-PCB Se-301-5.0

Ibhulokhi yesikulufo se-PCB esingu-301-5.0 ifakwa ngqo kwi-PCB kunokuba ifakwe ku-DIN rail, okumelela uxhumano lokugcina phakathi kwezintambo zasensimini nezinhlelo zokulawula ze-elekthronikhi. Ngoba ingenye yezingxenye zokuxhumanisa zezinga le-PCB ezisetshenziswa kakhulu emishinini yokulawula yezimboni, isebenza njengencazelo yethu yokubhekisela yomklamo wamabhulokhi e-terminal anabantu abaningi.

Enye imininingwane edinga ukunakwa ngokukhethekile yi-torque yokuqinisa engu-0.4Nm. Lokhu kuphansi kakhulu kunezithili ezinkulu ze-DIN rail terminal (ngokuvamile ezidinga u-0.5-0.8Nm), ngoba ukufakwa kwe-PCB akunikezi ukwesekwa okufanayo komshini wokufakwa kwe-DIN rail. Ngoba Ukuqinisa kakhulu kungaphula i-PCB trace noma i-block housing, ngincoma ukusebenzisa i-screwdriver ye-torque elinganiswe ku-0.4Nm lapho uqeda izintambo kumabhulokhi angu-301-5.0. Ekwenzeni kwethu, sinamathuluzi e-torque angu-0.4±0.05Nm ajwayelekile kuzo zonke izinhlangano zamabhulokhi e-PCB terminal.

Iphimbo lika-301-5.0 elingu-5.0mm lichaza nobuningi bentambo ku-PCB uqobo. Kwemihlangano ye-J-Guang enezinsika eziningi engu-301-5.0, sincoma ukucacisa inguqulo yezinsika eziningi ezihlanganiswe efektri kunokuba izinsika ngazinye ezisika insimu, ukuqinisekisa ukubekezelelana kwephimbo okulinganayo kuyo yonke inhlangano.
