Arduino 4 Relay Shield A000110

The Arduino 4 Relays shield is designed as a solution for driving those high power loads that cannot be driven by Arduino's digital IOs due to current and voltage limits. The shield features 4x relays, with each relay providing 2 pole changeover contacts (NO and NC). The 2 changeover contacts have been put in parallel in order to increase output current limits.

The relays are controlled by the following Arduino board pins:

Relay 1 = Arduino pin 4

Relay 2 = Arduino pin 7

Relay 3 = Arduino pin 8

Relay 4 = Arduino pin12

* Compatible with all Arduino boards, 5V and 3.3V

* 4x Status LEDs

* Power provided by base board

* Operating voltage 5V

* Maximum switching capacity 60W

* 6x TinkerKit IO interfaces
