This Relay as it says, is an M5Unit that implements relay functions. The relay can be used as an electric operated switch, using an electromagnet to mechanically operate a switch where it is necessary to control a large power load circuit by a separate low-power signal such as digital signal output from a microprocessor.

The Relay support input voltage goes up to 30V DC and 220V AC.

There are 3 pins named: ON, OFF, and COM. You can program it to make COM connect to ON or OFF, just like high and low output of a digital GPIO.
