Hi,
This is the first time I post on this forum & I’m writing because I have an Issue that’s bugging me for some time.
My Hardware setup:
- Raspberry PI 3
- 5V 2.5Amp Original Power adapter
- 8 Channel Module Relay
**The main problem I have is that the 8 CH Relay module has this annoying sound similar as if the relays were changing state but it isn’t. The relays actually aren’t changing their state. First i Thought it wasn’t receiving enough power so i went from a 5Vdc 2 amp power adapter to a 5Vdc 2,5Amp power adapter. But it keeps on doing this sound (less than before though). It even sounds if it’s idle or it has the LAN utp cable disconected. **
Here you can find a youtube link so you can watch & hear what I’m talking about.
As you can see I have my Raspberry PI mounted inside a 9U Wallmounted Rack with the rest of my network equipment and my Plex server inside of it.
May I need more amps or maybe ask for the 8ch relay module Guarantee?
