Customer:
I recently purchased a relay module from you. I want to make the relay work independently without the module, but I’m having trouble with it. Could you explain in detail what your relay module is - specifically what’s on the PCB, which components it has, and why each component is necessary?

Kupio sam nedavno od Vas modul s relejom, ono što sam želio napraviti je samostalan rad releja bez tog modula, nije mi išto od ruke. Molim Vas ovim mailom da mi odgovorite i objasnite detaljno cijeli taj Vaš modul, ali ne u obliku releja, nego u obliku te Vaše pločice na kojoj je relay, što ona sadrži, koje komponente ima i zašto nam je potrebna bas ta komponenta…
Hvala

You can find the usage instructions for the relay module here: https://e-radionica.com/hr/blog/2017/12/10/kkm-relej/
Instead of connecting the control pin to a Croduino, you can control the relay by connecting it directly to GND or +5V to turn it on and off.
The relay PCB consists of a transistor and an optocoupler. The transistor amplifies the control signal, while the optocoupler provides galvanic isolation (optical, not electrical) between the two circuits.

hvala Vam na kupovini kod nas. Ovdje možete pronaći upute za korištenje modula s relejom: https://e-radionica.com/hr/blog/2017/12/10/kkm-relej/
umjesto da kontrolni pin spojite na Croduino, njegovim spajanjem na gnd ili +5V ćete paliti i gasiti relej.
Pločica s relejom sastoji se od tranzistora i optocouplera. Ako se dobro sjećam, o tranzistoru sam Vam već pisao, dok optocoupler kao i uvijek ima svrhu da galvanski(putem svjetla, ne električki) izolira dva kruga.
Ako imate konkretnih pitanja u vezi kruga, slobodno postavite
