Mojule oa relay ke eng? Tlhaloso e qaqileng ea moelelo oa eona, mosebetsi le tšebeliso.
Mojule oa relay ke sesebelisoa se senyenyane sa elektronike se lumellang matšoao a matla a tlaase ho laola thepa ea matla a phahameng. E sebetsa e le borokho pakeng tsa tsamaiso ea taolo-e kang PLC, Arduino, kapa microcontroller-le lisebelisoa tse phahameng tsa motlakase tseo e lokelang ho li sebetsa. Ho utloisisa moelelo oa li-relay module ho u thusa ho rala litsamaiso tse sireletsehileng, tse sebetsang hantle haholoanyane.
Relay Module e Etsa'ng? (Moelelo)
Mojule oa relay o sebetsa joalo ka sesebelisoa sa motlakase se laoloang hole. E sebelisa lets'oao le lenyenyane la ho kenya, e ka bulela kapa ea tima meroalo e meholo ea motlakase, joalo ka lienjineri, li-circuits tsa mabone, lifenehi, lipompo le mechini ea indasteri. Sena se thibela li-controller tse nang le kutloelo-bohloko hore li se ke tsa pepeseha ka kotloloho ho matla a phahameng kapa hona joale.
Mosebetsi oa Relay Module ke Ofe?
Mosebetsi o ka sehloohong oa module ea relay ke ho fetola ka mokhoa o sireletsehileng. E sebelisa lets'oao la taolo ea matla a tlase ho sebetsa lisebelisoa tse matla a matla, motlakase o arola lipotoloho tsa taolo ho lipotoloho tsa mojaro, o sireletsa balaoli le li-microcontrollers ho senya, mme o fana ka taolo e tšepahalang ea ON / OFF bakeng sa boiketsetso.
Ka mohlala, microcontroller ea 5V e ka fetola lebone la 220V AC ka mokhoa o sireletsehileng ka module ea relay.
Phapang Pakeng Tsa Relay le Relay Module
Relay ke karolo ea switching feela, athe module ea relay e kenyelletsa lisebelisoa tse ling tsa elektroniki joalo ka li-diode tsa ts'ireletso, li-transistors, li-LED tsa matšoao, lihokelo tsa terminal, 'me ka linako tse ling optocoupler isolation.
Mojule oa relay o bonolo ebile o bolokehile ho sebelisoa mererong ea othomathiki hobane li-wiring, ts'ireletso le li-circuits tsa ho khanna li se li hahiloe.
Sepheo sa Relay
Sepheo sa relay ke ho laola potoloho ea matla a phahameng ka ho sebelisa letšoao la matla a tlaase. U tla fumana li-relay ho li-motor starters, litsamaiso tsa HVAC, mechini ea indasteri, liphanele tsa taolo ea motlakase, lits'ebetso tsa ts'ireletso le lisebelisoa tse bohlale tsa lapeng. Li ntlafatsa polokeho, li fokotsa kotsi, 'me li eketsa ts'epo ea sistimi.
Relay Module e sebetsa Joang?
Ka hare ho mojule o mong le o mong oa relay ho na le coil ea electromagnetic, switching contacts (NO/NC), le selemo. Ha coil e amohela voltage, matla a khoheli a koala kapa a bula mabitso, a matlafatsa sesebelisoa se hokahaneng. Ha matla a tlosoa, selemo se khutlisetsa mabitso sebakeng sa bona se tloaelehileng.
Sena se lumella litsamaiso tsa othomathike ho laola meroalo e matla ntle le khokahanyo e tobileng ea motlakase.
Mokhoa oa ho Sebelisa Mojule oa Relay
Hokela lithakhisa tsa mojule ho molaoli (Arduino, ESP32, PLC, joalo-joalo), ebe o hokela liteishene tsa COM / NO / NC mojaro oa hau. Kamora ho matlafatsa mojule, romella lets'oao la taolo mme relay e tla bulela sesebelisoa kapa HO TŠOA.
Mohlala: Microcontroller e fumana taelo ea Wi-Fi ho tsoa fonong ea hau, relay ea sebetsa, 'me sesebelisoa sa hau sea buleha.
Mokhoa oa ho Lekola Mojule oa Relay
Kenya matla le lets'oao la taolo - o lokela ho utloa "tobetsa."
Ka multimeter, hlahloba tsoelo-pele:
Ha HO ON → COM le NO li na le tsoelo-pele
Ha TIMA → COM le NO lia buloa
Haeba ho fetoha le ho tsoela pele ho fetoha ka nepo, mojule oa relay o sebetsa.
Na li-Relay le Relay Modules lia Tšoanang?
Che. Relay ke karolo e le 'ngoe. Mojule oa relay o kenyelletsa relay eo hammoho le potoloho ea ho khanna le ts'ireletso, e etsa hore e bolokehe ebile e le bonolo haholoanyane bakeng sa litsamaiso tsa othomathike.
Lisebelisoa tsa Mojule oa Relay ea Matla
Li-module tsa phetisetso ea motlakase li sebelisoa taolong ea makoloi, HVAC, li-compressor, li-automation tsa indasteri, lipompo, li-valve le li-heaters. Litsamaisong tse kholoanyane, li ntlafatsa ho ts'epahala le ho sireletsa liboto tsa taolo hore li se ke tsa senyeha.
Bakeng sa ts'ireletso ea enjene e ngata, li-relay tsa ABB TF tse futhumatsang li sebetsa ka mokhoa o ts'oanelang ka li-module tsa relay:
Matla a ho laola: 690V AC
E Lekanyelitsoe Ts'ebetso ea Hona Joale: 42A, 65A, 96A, 140A
Likhokahano tse Loketseng: AF09 - AF140
Qetello
Li-module tsa relay li etsa hore boiketsetso bo bolokehe, bo tenyetsehe, 'me bo sebetse hantle. Li lumella litsamaiso tsa taolo ea matla a tlase ho laola meroalo e matla haholo, e etsa hore e be ea bohlokoa lits'ebetsong tsa elektronike tsa lapeng le tsa indasteri. Ho sa tsotellehe hore na ho aha morero oa DIY kapa ho ntlafatsa lisebelisoa tsa fektheri, ho khetha mochine o nepahetseng oa relay ho tiisa ts'ebetso e ka tšeptjoang le bophelo bo bolelele ba tšebeletso.
