Nyob zoo cov phooj ywg hnub no kuv yuav ua ib qho SSR cais, Raws li peb paub treditional relays muab galvanic cais tab sis nws yog electromechanical hloov raws li nws cov neeg raug puas ntsoog dhau sijhawm, yog li kuv txiav txim siab los ua Solid State Relay Rau load hloov.

Kauj Ruam 1: Optocoupler Triac AC Output 1 Channel 400VDRM 6-Pin PDIP

MOC3021 yog Otocoupler cov khoom siv no yog lub luag haujlwm hloov pauv lub ntsiab triac BT136 thiab tseem muab Kev Kho Qhov Muag Sib cais.

Kauj ruam 2: BT136

BT136 yog 4A 500V Triac siv hauv cov qauv no kom hloov ON/OFF AC thauj khoom,

Ua hauj lwm

Raws li optocoupler tau txais 5v DC los ntawm Ib qho MCU lossis Lub Hwj Chim Source nws sab hauv teeb pom kev zoo, tom qab lwm Sab PhotoTriac (Transister) tig ON (Optocoupler tuaj yeem hloov AC thauj khoom tab sis nws tuaj yeem tswj tau ob peb mA tam sim no, yog li peb siv BT136 nws tuaj yeem ua haujlwm 4 Amps) nrog lub rhaub dej kub,) ces BT136 kuj tig rau, Tam sim no peb tag nrho SSR tau nquag,

Cons

Tsis muaj zog raws li Cov Kev Sib Tham Sib Tham,

Pros

  1. siv zog tsawg dua
  2. muab qhov muag cais
  3. lub sijhawm teb sai dua
  4. lub neej ntev
  5. tsis muaj suab nrov

Sib sau ua koj tus kheej yog tias koj muaj teeb meem cuam tshuam nrog txoj haujlwm no tawm lus, koj tseem tuaj yeem mus ntsib kuv li channel Nyem rau qhov no rau ntau txoj haujlwm.

ua tsaug
