Description
5V Single Channel Relay Module with Optocoupler
This 1-channel 5V control Single-Pole Double-Throw (SPDT) High-level trigger AC power relay board can be controlled directly via a microcontroller and switch up to 10A at 250 VAC. The inputs of 1 Channel 5V Relay Module are isolated to protect any delicate control circuitry.The default state of the relay when the power is off for COM (Power) to be connected to NC (Normally Closed). This is the equivalent of setting the relay board IN pin to HIGH (has +5V sent to it).
A wide range of microcontrollers such as Arduino, AVR, PIC, ARM, etc can be used to control this 5V relay module
NOTE: There Is Printing Mistake On Module 250VAC To 30VAC And 125VAC to 28VAC But Working Will Be the Same.

Customer Reviews
I actually purchased this relay not expecting to use the LOW trigger option. I actually just wanted a simple 5v relay that I planned to control via Mosfet.
I used this to trigger the sleep mode of a Crown XLS series pro amp in a home audio application. Works great and now I don't have to turn off and on the amp every time I want to use it, it just turns on and off when the receiver turns on and off. I got the 5V version just because my receiver happened to have a switched 5V USB port on the back. No complaints, worked like a charm. Been using it for a few weeks now without any issues.
Great for Arduino controlled devices that need Mains voltage. I used one of these to control the pump on my hydroponic system triggered by an Arduino microcontroller and it worked great.
So far they work as they should. I will update if they stop working.
I'm buying another pair for another project. Well designed and work as advertised. Easier and cheaper than buying the parts and making my own board...
I needed a relay to trigger a 12 volt item based on a 5 volt output from a computer. This worked perfectly! Having the 3 wires on the 5 volt input side was a bit odd for me, but reading other reviews and questions I was able to figure it out by simply jumpering between the +5V and the signal input (since I was signaling high).
I've been using one of these in a raspberry pi project to turn a water pump on and off and it has been working just fine for awhile now.
Using one of these with an arduino to turn off my 3d printer using Octoprint. The other I'm usign to turn on/off lighting.Works great, would recommend
Any 5v input would trigger the relay. It works as it should. I would definitely buy again.
Just what my son needed for a freshman Engineering project.
