Wannan yana ba da damar tsarin sarrafa kansa don sarrafa nauyi mai ƙarfi ba tare da haɗin wutar lantarki kai tsaye ba.

Yadda Ake Amfani da Module Relay

Haɗa fil ɗin shigarwar module ɗin zuwa mai sarrafawa (Arduino, ESP32, PLC, da sauransu), sannan haɗa tashoshi na COM/NO/NC zuwa nauyinka. Bayan kunna na'urar, aika siginar sarrafawa kuma relay zai kunna na'urar ON ko KASHE.
Misali: Microcontroller yana karɓar umarnin Wi-Fi daga wayarka, gudun ba da sanda yana kunna, kuma na'urarka tana kunna.

Yadda ake Gwada Module Relay

Aiwatar da wuta da siginar sarrafawa - ya kamata ku ji "danna."
Tare da multimeter, duba ci gaba:

Lokacin ON → COM da NO suna da ci gaba

Lokacin KASHE → COM da NO suna buɗewa

Idan sauyawa da ci gaba sun canza daidai, tsarin relay yana aiki.

Shin Relays da Relay Modules iri ɗaya ne?

A'a. Relay abu ne guda ɗaya. Model na gudun ba da sanda ya haɗa da wannan gudun ba da sanda tare da tuƙi da kewayawa, yana mai da shi mafi aminci kuma mafi dacewa ga tsarin sarrafa kansa.

Aikace-aikacen Module Relay Power

Ana amfani da na'urorin watsa wutar lantarki a cikin sarrafa mota, HVAC, compressors, sarrafa kansa na masana'antu, famfo, bawuloli, da dumama. A cikin tsarin da ya fi girma, suna inganta dogara da kuma kare allon kulawa daga lalacewa.

Don kariyar wuce gona da iri, ABB TF thermal overload relays suna aiki ba tare da wata matsala ba tare da na'urorin relay:

Ƙarfin wutar lantarki: 690V AC
