I bought this relay to control the power to the motors of my Ender 3 and it has worked very well so far. Very easy to use with the raspberry pi and the pin connections are clearly labeled on the PCB so setup was very easy. Highly reccomend!

These relays seem well made. I'm using a microcontroller through a level shifter to control the relay at 5 volts. If the microcontroller loses power with the relay on, it stays on. I solved this by adding a 1K Ohm resistor between the signal input and ground on the relay.

I built an automated can crusher using an old Garage Door motor. I need to apply power for motor to crush a can and then reverse the direction to release the can. This constant on/off/on/off of the motor burned the contact of two 10amp relays. Guess what, it draws more than 10 amps :-0 Well this unit if well built circuit board and components. Relays are heavier duty than my previous selection so in time I will see if they can take a liking and keep on ticking. I know that probably does not help you but in short the board, components relays are very well made and will work great for most 30amp or less switching. I recommend.

Built a fan control module with this . It worked when bench testing and when tested while plugged into the vehicle. Each of the four fans were powered by its own relay on the board, instead of one relay powering two as the original controller was. So it was not strained in any way. Once permanently installed all of the fans would run once the ignition was switched on. I did some diagnostics and found that this module failed. The relays would close as soon as power was applied to the board, even with all of the signal wires disconnected. It’s apparently an internal failure. I wouldn’t waste my time trying to use this module for anything. It would be a complete waste of time.

I have purchased and included ten (10) of these in a solar project. Knock on wood, I have had great success, as each relay has performed as expected. What's more, the board is beautifully laid out with a legend printed right on the board. Only mistake I made was to use 5v from my Arduino project to power the relays, which draws more power than the Arduino board can handle. This was my bad, and once I supplied 5v from an independent power source, specifically for powering the relay(s), all was good. What's more, unlike many Internet of Things accessories, these relays have excellent input and output connectors, that allow me to use high quality (thicker) wire than others. Finally, the board is supplied with helpful relays, one of which indicates power to the board / relays, and then one for each relay, to indicate the relay is energized. I will buy more and do recommend to friends and colleagues!

After installing this unit I find out that one of the relays doesn't close on operating. Fortunately, the project only needed 3 relays so I just moved the wires to the spare one. Lesson here: Test ALL the relays in both open and closed positions with a continuity checker to make sure they actually work. The dead relay did open the NC contact but would not close the NO contact, so the coil was fine but the relay's contacts were not. Otherwise, seems like a nice product. Hope it holds up because changing the whole module now would be a real b***h.

These relays are tough and dependable, easy to install.

I bought this relay module to control a swimming pool pump via an Arduino microcontroller. This module works well. Functionally. However, the relay contact ratings for form C contacts are not the same between normally open and normally closed. If you plan to use normally closed contacts, the current rating is much less then is advertised. Consult the songle relay datasheet before you purchase this module.I'll provide an update later after I put the contacts under load.UPDATE: I had trouble connecting pool pump wiring to this module's terminal strip because the terminal strip width is not wide enough to accommodate a properly sized spade lug (which crimps onto the wiring). My wiring was 12AWG which aligns with the current rating of this module's relay. Good luck finding a spade lug for 12AWG wiring that will slide into this module's terminal strip. I had to splay the stranding of the wiring into two halves. This worked and the module is now powering my pool pump at 240VAC/ 7A continuous. Temp rise of the relay was 14 degC over ambient after 1 hour of operation.This relay module is performing but there are some nuances that you will have to deal with.
