This module should be powered with 5v, which is assemble all the parts as shown in the schematic diagram. • vcc to 5v arduino pin; This relay module provides four relays that are rated for 7a at either 28vdc or 10a at 125vac.

Each relay has a normally open (no) and a normally closed (nc) the following schematic shows how to connect the module to an arduino, i have only shown one device (lightbulb) connected to one relay.

Full technical support for electronics, robotics equipments. 4 relays are included in this module, with nc ports means normally connected to com and no ports means normally open to com. How to use relay to control high power load? Below is the arduino code which we have used to demonstrate this relay module:
