Excellent Industrial Relay System

This relay module is a phenomenal industrial and scientific relay for triggering other devices.As a result of my tests, I determined that it is incredibly efficient and reliable for large-scale industrial projects. The opto isolated design provides added safety and reliability, ENSURING optimal performance. Its compact size and easy installation make it a great option for any industrial electrical system. The only downside is that it requires specialized knowledge to use, making it less…

Pros
  • Opto isolation provides protection against high voltage spikes and surges.
Cons
  • Interference from nearby electrical signals could trigger false readings or malfunctions.

Exactly what I needed for my projects

Made exactly as it should be. Would buy again. A bit confusing with jumpers, 3.3V input and trigger pin. I found that VCC was the power supply for the relay, the 3V command pin was the enable pin, and ground naturally acted as ground. After understanding this part for my project, they worked fine for what I was using them for (low voltage application). I think the seller explains this in the product documentation as well, but I'm not sure I read it until I tried to use it.

Pros
  • All the best!
Cons
