Customer:

I have a question about the relay board with 8 outputs. I’m asking about the additional power supply that should be connected for the optocoupler output. Please let me know if you need any clarification.

Ovaj upit je o relejnoj pločici s 8 izlaza. Meni ovo izgleda kao da niste dobili proložen mail koji je prethodio ovom upitu (a to je zapravo Vaš odgovor), pa Vam za svaki slučaj to prilažem.

Riječ je o dodatnom napajanju koji bi se trebao spojiti za izlaz optokaplera. Svakako mi javite ako Vam niti sada nije jasno. LP,

Soldered Support:

Connect the GND (ground) together with the microcontroller and any other power supply. Connect only the positive voltage from the separate power supply that you want to use to power the relay board to the positive voltage input on the board (marked VCC).

isprike :slight_smile: spojite gnd(ground) zajedno s Croduina i bilokojeg drugog napajanja, a samo pozitivan napon s posebnog napajanja s kojime želite napajati pločicu s relejom spojite na ulaz pozitivnog napona na pločicu(oznaka VCC).
