These Jessine 24v relays work great so far. I've tested them out with Arduinos and microcontrollers. They have selectable hi/low trigger.They work well with very simple code, just declare which pin is your trigger pin on arduino and set that between "high" or "low" with the digitalwrite command. Easy peasy.The relay needs a 24v supply connected to the DC + and -. i am using a 24v 500ma supply and that's working great. Connect the arduino digital pin to the input pin on the relay board and don't forget to connect GND on the arduino to the DC - minus terminal on the relay or it won't work.I'm using these to make my own smart plugs and it's working great!

I like these pretty well. Realistically (for me), they simply put the relay on a mountable circuit board. However, they also make it easy to change it from hi/lo switching of the relay itself via the jumper pins. And LED's are a nice touch to visually monitor the units power and status.These can clean up the appearance of your project a bit. And make it a little more professional looking. I have found they are available in 5 and 12 volt dc versions as well.I like these and recommend them.
