Arduino 4 Relays Shield를 사용하면 Arduino가 높은 전력 부하를 견딜 수 d있으며, Arduino가 Arduino의 디지털 핀으로 직접 제어 할 수 없는 고전력 부하를 견딜 수있게 합니다.

Arduino 4 Relays Shield 에는 4개의 릴레이가 있으며 각 릴레이에는 2 극 전환 접점 (NO 및 NC)이 있습니다. 네 개의 LED는 각 릴레이의 켜기 / 끄기 상태를 나타냅니다.

Arduino 4 RELAYS SHIELD

The Arduino 4 Relays Shield allows your Arduino driving high power loads.

The Arduino 4 Relays Shield allows your Arduino driving high power loads that cannot be controlled directly by Arduino's digital pins. The Shield features four relays, each relay with 2 pole changeover contacts (NO and NC). Four LEDs indicate the on/off state of each relay.



Overview

The Arduino 4 Relays Shield is a solution for driving high power loads that cannot be controlled by Arduino's digital IOs, due to the current and voltage limits of the controller.

The Shield features four relays, each relay provides 2 pole changeover contacts (NO and NC); in order to increase the current limit of each output the 2 changeover contacts have been put in parallel. Four LEDs indicate the on/off state of each relay.
