This section will show you how to switch AC outlets using a Four Outlet Power Relay Module. You can also use this method to control any device that looks for 5V logic (such as an Arduino input). 

RFID WIZ 5V Logic Output


The RFID WIZ has a white JST PH (2mm pitch) jack with 2 pins

  • GND - always stays at 0V
  • SIG - switches from 0V to 5V when the relay flips

A 2-pin  JST cable is included with your kit, and can be used to connect to any device looking for a 5V logic input. 

The power relay module has corresponding inputs:
