Un isilayidi sombuso oqinileyo, okanye iSSR (iSylid State Relay), sisixhobo esisebenza injongo enye njengereyiti eqhelekileyo, kodwa sineengenelo ezithile phezu kwaso njengoko uza kubona kweli nqaku. Ukuba awukhumbuli kakuhle ukuba yintoni i-relay okanye yenzelwe ntoni, unako kwakhona Bona ulwazi oluninzi kweli nqaku.
Sele sikuthethile oko, makhe sibone yonke into ekufuneka uyazi malunga noku isixhobo sombane:
Yintoni i-electromechanical relay?
Un i-electromagnetic relay, edla ngokubizwa ngokuba yi-relay, sisixhobo sombane esisetyenziselwa ukulawula isekethe yombane ngokusetyenziswa kwekhoyili ye-electromagnetic. Iyisiseko sokutshintsha okwenziwa ngokufaka okanye ukususa umsinga wombane kwikhoyili ye-relay. Xa i-coil inamandla, idala intsimi yamagnetic ekhangayo okanye igxotha i-lever okanye itshintshe ngaphakathi kwi-relay, ukuvula okanye ukuvala oonxibelelwano lombane, kuxhomekeke ekubeni ngaba yi-NC okanye NO, njengoko sibonile kwelinye inqaku endikucebisayo. funda ekuqaleni.
Ezi relay zisetyenziswa kwiintlobo ngeentlobo izicelo ukwenza imisebenzi efana ukutshintshwa kweesekethe zombane zamandla aphezulu okanye ukuhlukaniswa kombane phakathi kweesekethe ezimbini ezisebenza ngeentlobo ezahlukeneyo zangoku, njenge-DC kunye ne-AC. Ziluncedo ngakumbi kwiimeko apho kufuneka ulawule isekethe ukude okanye xa ufuna ukwahlula isiphaluka solawulo ukusuka kumandla aphezulu. Ukuhanjiswa kunokufumaneka kuluhlu olubanzi lwezixhobo kunye neenkqubo, ukusuka kwizixhobo zasekhaya kunye nezixhobo zoshishino ukulawula kunye neenkqubo ezizenzekelayo.
Yintoni i-slide state relay?
Un Ukudluliswa kombuso okuqinileyo sisixhobo sokutshintsha i-elektroniki esivumela ukuhamba kwamandla ombane xa i-current encinci isetyenziswa kwii-terminals zayo zokulawula, okanye ithintele xa kungekho msinga osetyenziswayo. Oko kukuthi, kule ngqiqo ifana kakhulu nokusebenza kwe-relay eqhelekileyo.
Ezi zikhuseli eziqinileyo zibandakanya i-sensor ephendula kumqondiso wolawulo, i-electronic solid state switch elawula isiphaluka somthwalo, kunye nesixhobo sokudibanisa esenza ukuba sitshintshe ngaphandle kwesidingo sokuhambisa amacandelo oomatshini, njengakwimeko ye-electromagnetic. Kwelinye icala, ezi relays zinokuyilwa ukuba zitshintshe zombini i-AC kunye ne-DC yangoku.
Ukwenza oku kwenzeke ngaphandle kwamalungu ashukumayo, iisemiconductors zamandla, ezifana ne-thyristors kunye ne-transistors, ukulawula imisinga ukuya kuthi ga kwi-100 amperes ngamandla. Ngaphezu koko, ukuba yimeko eqinile, babonakaliswe ngokukwazi kwabo ukutshintshela kwisantya esiphezulu kakhulu, ngokulandelelana kwee-milliseconds, xa kuthelekiswa nokuhanjiswa kwe-electromechanical, kwaye abanalo uqhagamshelwano lomatshini oluguga ngokuhamba kwexesha. Noko ke, asizizo zonke iingenelo, njengoko siza kubona kamva.
Ukwahlula kombane phakathi kweesekethe ezimbini, isiginali yolawulo idityaniswe kwisekethe yolawulo, kwaye uninzi lwee-SSRs zisebenzisa ukudibanisa optical. Oku kuthetha ukuba amandla ombane olawulo avule i-LED yangaphakathi ekhanyisa kwaye isebenze i-photosensitive diode (photovoltaic), ethi, ilawule i-TRIAC (esetyenziswa kwi-AC), i-SCR okanye i-MOSFET (idla ngokubakho enye okanye ezininzi ngokuhambelana neCC) ukutshintshela kwaye uhambe ukusuka ekuvuleni ukuya ekuvaleni okanye ngokuphambanayo…

Kuphi ukuthenga i-slide state relay?
Ukuba ufuna thenga i-relay yombuso oqinileyo, unokuyithenga kancinci kakhulu kwiivenkile ezikhethekileyo okanye kumaqonga okuthengisa kwi-intanethi njengeAmazon:
Sebenzisa i-slid state relay kunye ne-Arduino
Ukusebenzisa i-slide state relay kunye ne-Arduino, uxhulumaniso lulula kakhulu, ngakumbi ukuba usebenzisa imodyuli ye-SSR. Ukuqhagamshela le relay kwibhodi yeArduino, kufuneka yenza olu nxibelelwano lulandelayo:
- I-DC +: le ngeniso ye-relay iqhagamshelwe kuqhagamshelwano lwe-5v yebhodi ye-Arduino.
- DC-: Le enye igalelo relay idibanisa GND okanye umhlaba uqhagamshelwano lwebhodi Arduino.
- I-CH1: ukuba yi-channel-slid state relay, njengaleyo siza kuyinika njengomzekelo, eli galelo lokudluliselwa liya kudityaniswa nemveliso yedijithali ye-Arduino yokulawula, umzekelo, i-D9.
- NO / C: ziziphumo ze-slid state relay eya kudityaniswa nesixhobo esifuna ukusilawula. Umzekelo, ibhalbhu yokukhanya. Thatha ingqalelo i-database ye-relay oyithengayo, kunye nemida ebekiweyo. Ngokomzekelo, abanye banyamezela kuphela umthwalo we-250V AC kunye nobukhulu obukhulu be-2A, qiniseka ukuba ungagqithisi ...
Senditshilo, ngoku makhe sibone ingacwangciswa njani, usebenzisa lo mzekelo ulula womzobo:
const int pin = 9; //Pin de control del relé en el que lo hayas conectado, en este caso D9.
void setup()
{
Serial.begin(9600); //Iniciar puerto serie
pinMode(pin, OUTPUT); //Definir pin D9 como salida para el envío de señal.
}
void loop()
{
digitalWrite(pin, HIGH); // Poner el D9 en estado alto para activar el relé
delay(5000); // Esperar 5 segundos
digitalWrite(pin, LOW); // Poner el D9 en estado bajo, para desactivar.
delay(5000); // Esperar 5 segundos
}
Njengoko ubona, yikhowudi elula kakhulu, ngoko ungayiguqula kwaye ufunde indlela yokusebenzisa i-relay. Kule meko siye sakha i-loop ukwenzela ukuba i-relay ihlale ihamba ukusuka kwelinye ilizwe ukuya kwelinye ...
