Yintoni imodyuli yokudlulisela? Inkcazo eneenkcukacha yentsingiselo, umsebenzi, kunye nokusetyenziswa kwayo.

Imodyuli ye-relay sisixhobo esincinci sombane esivumela izibonakaliso zamandla aphantsi ukulawula izixhobo eziphezulu zamandla. Isebenza njengebhuloho phakathi kwenkqubo yokulawula-njenge-PLC, i-Arduino, okanye i-microcontroller-kunye nezixhobo eziphezulu ze-voltage kufuneka zisebenze. Ukuqonda intsingiselo yemodyuli yodluliselo kukunceda uyile iindlela ezikhuselekileyo nezisebenzayo zokuzisebenzela.

Yenza ntoni iModyuli yoRelay? (Intsingiselo)

Imodyuli ye-relay isebenza njengokutshintsha kombane olawulwa kude. Isebenzisa umqondiso omncinci wokungenisa, inokuguqula okanye icime imithwalo emikhulu yombane, enje ngeenjini, iisekethe zokukhanyisa, iifeni, iimpompo, kunye noomatshini bemizi-mveliso. Oku kuthintela abalawuli abanovakalelo ukuba bangavezwa ngokuthe ngqo kumbane ophezulu okanye umsinga ophakamileyo.

Yintoni uMsebenzi weModyuli yoRelay?

Umsebenzi ophambili wemodyuli ye-relay kukutshintsha ngokukhuselekileyo. Isebenzisa isignali yokulawula i-low-voltage ukuze isebenze izixhobo eziphezulu zamandla, ngombane ihlukanisa iisekethe zokulawula ukusuka kwiisekethe zomthwalo, ikhusela abalawuli kunye ne-microcontrollers emonakalweni, kwaye inikezela ngolawulo oluthembekileyo lwe-ON / OFF kwi-automation.
Ngokomzekelo, i-microcontroller ye-5V inokutshintsha ngokukhuselekileyo isibane se-220V AC ngokusebenzisa imodyuli yokubuyisela.

Umahluko phakathi kweRelay kunye neModyuli yoRelay

I-relay yinto yokutshintsha kuphela, ngelixa imodyuli ye-relay ibandakanya i-electronics eyongezelelweyo efana ne-diode yokukhusela, i-transistors, i-LED yesalathisi, izixhumi ze-terminal, kwaye ngamanye amaxesha i-optocoupler isolation.
Imodyuli yokudlulisa ilula kwaye ikhuselekile ukuyisebenzisa kwiiprojekthi ezizenzekelayo kuba iingcingo, ukhuseleko, kunye neesekethe zokuqhuba sele zakhiwe ngaphakathi.

Injongo yeRelay

Injongo ye-relay kukulawula isiphaluka samandla aphezulu usebenzisa isignali yamandla aphantsi. Uya kufumana iilayidi kwiziqalisi zeemoto, iinkqubo zeHVAC, oomatshini bemizi-mveliso, iiphaneli zolawulo lombane, iinkqubo zokhuseleko, kunye nezixhobo ezihlakaniphile zasekhaya. Baphucula ukhuseleko, banciphise umngcipheko, kwaye bandise ukuthembeka kwenkqubo.

Isebenza Njani iModyuli yoKugqithiselwa?

Ngaphakathi kwimodyuli ye-relay nganye kukho i-coil ye-electromagnetic, abafowunelwa abatshintshayo (NO / NC), kunye nentwasahlobo. Xa ikhoyili ifumana i-voltage, intsimi yamagnetic ivala okanye ivula abafowunelwa, inika amandla isixhobo esixhunyiwe. Xa amandla esusiwe, intwasahlobo ibuyisela abafowunelwa kwindawo yabo eqhelekileyo.
Oku kuvumela iinkqubo ezizenzekelayo ukulawula imithwalo enamandla ngaphandle koqhagamshelo oluthe ngqo lombane.

Uyisebenzisa njani iModyuli yoRelay

Qhagamshela izikhonkwane zemodyuli kumlawuli (Arduino, ESP32, PLC, njl.), Emva koko uqhagamshele iitheminali ze-COM / NO / NC kumthwalo wakho. Emva kokunika amandla imodyuli, thumela isignali yokulawula kwaye i-relay iya kutshintsha isixhobo ON okanye OFF.
Umzekelo: I-microcontroller ifumana umyalelo we-Wi-Fi kwifowuni yakho, i-relay iyasebenza, kwaye isixhobo sakho siyavula.

UVavanya njani iModyuli yoRelay

Faka amandla kunye nophawu lolawulo - kufuneka uve "cofa."
Nge-multimeter, jonga ukuqhubeka:

Xa KU- → COM kwaye HAYI zinokuqhubekeka

Xa OFF → COM kwaye NO zivuliwe

Ukuba ukutshintsha kunye nokuqhubeka kutshintsha ngokuchanekileyo, imodyuli yokudlulisa iyasebenza.

Ngaba iiModyuli zoRelay kunye neRelay ziyafana?

Hayi. I-relay licandelo elinye. Imodyuli ye-relay ibandakanya ukuhanjiswa kunye nokuqhuba kunye nokukhuselwa kwesekethe, iyenza ikhuseleke kwaye ilungele ngakumbi iinkqubo ezizenzekelayo.

Izicelo zeModyuli yoKugqithiselwa kwamandla

Iimodyuli zokuhanjiswa kwamandla zisetyenziswa kulawulo lweemoto, i-HVAC, iicompressors, i-industrial automation, iimpompo, iivalvu, kunye nezifudumezi. Kwiinkqubo ezinkulu, ziphucula ukuthembeka kunye nokukhusela iibhodi zokulawula kumonakalo.

Ukukhusela ukugcwala kwemoto, i-ABB TF yokulayishwa kwe-thermal overload isebenza ngaphandle komthungo ngeemodyuli zokudlulisela:

Ukulawula umbane: 690V AC

Ireyithwe ngokuSebenza ngoku: 42A, 65A, 96A, 140A

AbaQhagamshelwa abafanelekileyo: AF09 - AF140

Ukuqukumbela

Iimodyuli zoRelay zenza i-automation ikhuseleke, ibe bhetyebhetye, kwaye isebenze kakuhle. Bavumela iinkqubo zolawulo lwamandla aphantsi ukuba zilawule imithwalo ephezulu yamandla, ibenza ibaluleke kuzo zombini ii-elektroniki zasekhaya kunye nezicelo zemizi-mveliso. Ingaba ukwakha iprojekthi ye-DIY okanye ukuphuculwa kwezixhobo zefektri, ukukhetha imodyuli efanelekileyo yokubuyisela iqinisekisa ukusebenza okuthembekileyo kunye nobomi obude benkonzo.
