Kodi gawo la relay ndi chiyani? Kufotokozera mwatsatanetsatane tanthauzo lake, ntchito yake, ndi ntchito zake.

A relay module ndi kachipangizo kakang'ono kamagetsi kamene kamalola kuti zizindikiro zotsika mphamvu zizilamulira zida zamphamvu kwambiri. Zimagwira ntchito ngati mlatho pakati pa dongosolo lolamulira-monga PLC, Arduino, kapena microcontroller-ndi zipangizo zamakono zomwe zimayenera kugwira ntchito. Kumvetsetsa tanthawuzo la gawo la relay kumakuthandizani kupanga makina otetezeka, ochita bwino kwambiri.

Kodi Relay Module Imachita Chiyani? (Tanthauzo)

Relay module imagwira ntchito ngati chosinthira chamagetsi choyendetsedwa ndi kutali. Pogwiritsa ntchito kachizindikiro kakang'ono, imatha kuyatsa kapena kuzimitsa katundu wamkulu wamagetsi, monga ma mota, mabwalo ounikira, mafani, mapampu, ndi makina aku mafakitale. Izi zimalepheretsa owongolera omwe ali ndi chidwi kuti asawonetsedwe mwachindunji ndi magetsi okwera kwambiri kapena magetsi apamwamba.

Kodi Ntchito ya Relay Module Ndi Chiyani?

Ntchito yayikulu ya module yolumikizirana ndikusinthira kotetezeka. Amagwiritsa ntchito chizindikiro chochepa chamagetsi kuti agwiritse ntchito zipangizo zamphamvu kwambiri, magetsi amalekanitsa mabwalo oyendetsa maulendo oyendetsa katundu, amateteza olamulira ndi ma microcontrollers kuti asawonongeke, ndipo amapereka odalirika ON / OFF kulamulira kwa automation.
Mwachitsanzo, 5V microcontroller ikhoza kusintha mosamala nyali ya 220V AC kudzera mugawo lopatsirana.

Kusiyana Pakati pa Relay ndi Relay Module

Relay ndi gawo losinthira, pomwe gawo lopatsirana limaphatikizapo zamagetsi zowonjezera monga ma diode oteteza, ma transistors, ma LED owonetsera, zolumikizira ma terminal, ndipo nthawi zina optocoupler kudzipatula.
Ma module a relay ndi osavuta komanso otetezeka kugwiritsa ntchito ma projekiti ongopanga okha chifukwa mawaya, chitetezo, ndi mabwalo oyendetsa amangidwa kale.

Cholinga cha Relay

Cholinga cha relay ndikuwongolera dera lamphamvu kwambiri pogwiritsa ntchito chizindikiro chochepa mphamvu. Mupeza ma relay mu zoyambira zamagalimoto, makina a HVAC, makina am'mafakitale, mapanelo owongolera magetsi, zida zachitetezo, ndi zida zanzeru zakunyumba. Amathandizira chitetezo, kuchepetsa chiopsezo, ndikuwonjezera kudalirika kwadongosolo.

Kodi Relay Module Imagwira Ntchito Motani?

Mkati mwa gawo lililonse la relay muli koyilo yamagetsi, ma switching contacts (NO/NC), ndi kasupe. Pamene koyiloyo ilandira voteji, mphamvu ya maginito imatseka kapena kutsegulira zolumikizana, ndikuyambitsa chipangizo cholumikizidwa. Mphamvu ikachotsedwa, kasupe amabwereranso omwe amalumikizana nawo kumalo awo abwino.
Izi zimathandiza makina odzipangira okha kuti azilamulira katundu wamphamvu popanda kulumikiza mwachindunji magetsi.

Momwe Mungagwiritsire Ntchito Relay Module

Lumikizani zikhomo za gawoli kwa wowongolera (Arduino, ESP32, PLC, ndi zina zotero), kenaka lumikizani ma terminals a COM / NO / NC pamtolo wanu. Mutatha kuyatsa gawoli, tumizani chizindikiro chowongolera ndipo cholumikizira chidzasintha chipangizocho ON kapena WOZIMA.
Chitsanzo: Microcontroller imalandira lamulo la Wi-Fi kuchokera pafoni yanu, relay imatsegulidwa, ndipo chipangizo chanu chimayatsidwa.

Momwe Mungayesere Relay Module

Ikani mphamvu ndi chizindikiro chowongolera - muyenera kumva "kudina."
Ndi multimeter, yang'anani kupitiliza:

Pamene ON → COM ndi NO amakhala ndi kupitiriza

Mukayimitsa → COM ndi NO zimatsegulidwa

Ngati kusintha ndi kupitiriza kusintha molondola, gawo la relay likugwira ntchito.

Kodi ma Relay ndi Relay Module ndi ofanana?

Ayi. Relay ndi gawo limodzi. Ma module a relay amaphatikizanso mayendedwe oyendetsa ndi chitetezo, zomwe zimapangitsa kuti zikhale zotetezeka komanso zosavuta kugwiritsa ntchito makina opangira makina.

Mapulogalamu a Power Relay Module

Ma module otumizirana magetsi amagwiritsidwa ntchito pakuwongolera magalimoto, HVAC, ma compressor, makina opanga mafakitale, mapampu, mavavu, ndi ma heaters. M'makina akuluakulu, amawongolera kudalirika ndikuteteza matabwa owongolera kuti asawonongeke.

Pachitetezo chochulukirachulukira pamagalimoto, mawotchi owonjezera a ABB TF amagwira ntchito mosasunthika ndi ma module a relay:

Mphamvu yamagetsi: 690V AC

Kuvoteledwa Panopa: 42A, 65A, 96A, 140A

Oyenerera Othandizira: AF09 - AF140

Mapeto

Ma module a relay amapangitsa kuti makina azikhala otetezeka, osinthika, komanso ogwira ntchito. Amalola machitidwe owongolera mphamvu zochepa kuti aziyendetsa katundu wamphamvu kwambiri, zomwe zimawapangitsa kukhala ofunikira pamagetsi apanyumba komanso ntchito zamafakitale. Kaya mukumanga pulojekiti ya DIY kapena kukweza zida za fakitale, kusankha gawo loyenera la relay kumatsimikizira magwiridwe antchito odalirika komanso moyo wautali wautumiki.
