Review on ๐ด Highly Effective 8 Channel 5V Relay Module with Optocoupler Isolation for High/Low Level Trigger Relay Support โ Red Board by Brandon Roberts
Great relay for computers and accessories
If you are looking for a relay I can assure you this relay will work great with a user configurable upper or lower trigger. I first ordered the ones I mistakenly ordered with only the low trigger. It stays on and only turns off when the relay trips. I suspect that since it's enabled 99% of the time it wears out quicker than this one, which can be set to start with high or low input. I just ordered more of these and just threw the low blue ones in the trash.
- Quick Change
- Almost never
