ℹ
Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•The Relay Shield 4x(4 relay)- enables you to manage consumer devices connected to the network 220V, switching power equipment: motors, pumps. Total have 4 relays with switching characteristics: AC 250V-10A, DC 60V-10A
•Normaly relay is that it separates the control channels and traffic channels. That gives protection to your microcontroller. But there is no guarantee of protection from very high currents
•For Relay Shield need external power supply 6-12V. For Relay Shield, use current about 400mA. With a jumper you can switch the power supply from an external to Vin board Arduino
