Arduino 4 Relays Shield

Arduino 4 Relays Shield is designed to drive high power loads that cannot be controlled by Arduino’s digital IOs due to the current and voltage limits. The A000110 shield features 4 relays, each relay provides 2 pole changeover contacts NO and NC. These 2 pole changeover contacts are placed parallelly in order to increase the current limit of each output. The A000110 4 relays shield consists of 4 LEDs that indicates the ON/OFF state of each relay. This 4 relays shield is compatible with all the Arduino boards with 5V and 3.3V standards. The A000110 4 relays shield is available in 53mm x 68.5mm dimensions.
