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.
