8 Channel 5V Relay Module

A Relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate the switch and provide electrical isolation between two circuits.

 

  • This 8 channel 5V relay has both optical and magnetic isolation,  providing a lot of protection to the inputs from electrical faults on the outputs.
  • Works well with both 3.3V and 5V logic (Raspberry Pi, Arduino, Teensy..), requiring little current drive.
  • Breadboard friendly, using Female/male dupont makes it extremely convenient for prototyping.
  • LED indicates its working status. Red refers to errors.
  • 3 terminals per SPDT relay.

All of these features make SainSmart relay a great component for automation projects.

Highly efficient and after having one constantly working for months on a RC car that I hacked using the Arduino I recommend it.

Great product at a great price!

Not much else to say other than it's perfect! Works great with Arduino if you add a transistor to prevent it from always being "on". Switches have NO and NC position so you can do just about anything you can imagine with it!

Good value for the relay.

Working flawlessly and carries a 120V circuit perfectly. The screws do have a tendency to wear but I just swapped one out that did.
