Customer:
Can I replace the relay on this module with a 12V relay and connect 12V to Vcc? Will the feedback components around the coil handle that, or will I have issues with the microcontroller?

Pozdrav, da li na ovaj vas modul sa relejom mogu zamijeniti relej sa 12v relejom i onda na Vcc spojiti 12v. Jesu li komponente u povratnoj vezi spule predvidjene za to tj. hoću li imati problem na croduinu. Hvala

Soldered Support:
You can replace it with a 12V relay and swap the input to 12V. However, you cannot use the same power supply for the Croduino in that case, since its maximum voltage is 5V.
The electronics on the module consist of a transistor to activate the coil, diodes for protection, and an optocoupler for isolation. Here is the schematic: http://howtomechatronics.com/wp-content/uploads/2015/09/HL-52S-Relay-Module-Circuit-Schematics.png?x57244

može se zamijeniti s 12V relejom te zamijeniti ulaz s 12V. Ali u tom slučaju ne smijete koristiti isto napajanje i za Croduino, čiji je maksimalni napon 5V.
Elektronika na modulu je zapravo tranzistor za aktivaciju špule, diode za zaštitu te optocoupler za izolaciju. evo sheme: http://howtomechatronics.com/wp-content/uploads/2015/09/HL-52S-Relay-Module-Circuit-Schematics.png?x57244
