Arduino 4 Relays Shield

• Voltage: 5V
• Channels: 4 (each one needs 15-20mA)
• Equipped with high-current relay, AC125V 10A ; DC24V 10A

Standard interface that can be controlled directly by microcontroller
Indication LED's for Relay output status

This shield has 4 active high relays. This means they turn on when you send a high signal from the micro-controller

• Relay 1 is controlled by digital pin 7
• Relay 2 is controlled by digital pin 6
• Relay 3 is controlled by digital pin 5
• Relay 4 is controlled by digital pin 4
