The Arduino 4 Relays Shield is designed as your best solution to drive high power loads that cannot be controlled by Arduino's digital IOs due to the current and voltage limits of the controller.
This shield features 4 relays, each relay provides 2 pole changeover contacts (NO and NC). These 2 pole changeover contacts are placed parallelly to increase the current limit of each output. It consists of 4 LEDs that indicate the on and off state of each relay.
