This 1 channel 5V 10A relay control board module with optocoupler is compliant with international safety standards, control and load areas isolation trenches it has a single relay a genuine. The inputs of the 1 Channel 5V 10A Relay Module are isolated to protect any delicate control circuitry.

5V 10A Relay Control Board Module input signal, signal, common Terminal and start conducting. It can be used as a single chip module for appliance control and work with both DC and AC signals where you can control the 220V AC load. A wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on can control it.

This 1 channel 5V 10A Relay Control Board Module Kit can be understood as a signal input with VCC cathode short-circuit triggered away; Low-level trigger refers to the signal voltage between the input terminal and Earth OV trigger. It can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way 1-channel relay module connection.

Used to control power to my 3D printer using M80 and M81 gcode commands.

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.

They work like they are supposed to

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 control of Mains voltages

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.

Works as it should

So far they work as they should. I will update if they stop working.

Good. Compact. Easy to Use.

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...

Did what I needed

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).

Works good

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.

Exactly what I needed, works great

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

Good quality

Any 5v input would trigger the relay. It works as it should. I would definitely buy again.

Good quality for the price

Just what my son needed for a freshman Engineering project.
