TheRelay Shield provides four high quality relay that can control high current loads to Arduino / Seeeduino boards. It also provides NO (Normally Open) / NC (Normally Closed) interface. It could be a nice solution for controlling devices that could not be directly controlled by Arduino's Digital I/Os. Standardized shield form factor enables smooth connection with Arduino and compatibles. The shield also has four LED indicators to show the on/off state of each relay.
Relays are useful in switching on/off AC appliances like fan, light, motor or high current DC actuators like solenoid valve etc...
Note: Exercise caution when dealing with AC. Get help from certified electrician.
Features
Arduino/Seeeduino Shield compatible
Relay screw terminals
Working status indicators for each relay
High quality relays
Provides NO/NC interfaces
Channel1 Interface
COM1 - Common pin
NC1 - Normally Closed. Will be connected with COM1 when RELAY1 pin is set low and disconnected when RELAY1 is high;
NO1 - Normally Open. Will be connected with COM1 when RELAY 1 pin is set high and disconnected when RELAY1 is low;
4 DIGITAL PINS TO CONTROL 4 RELAYS
RELAY1-RELAY4 pins could be connected directly with Arduino pin number of 7-4, so that four relays could be easily controlled by the Arduino

"中繼遮罩提供四高品質繼電器, 可控制高電流負載至 Arduino/Seeeduino 板。它也不提供 (通常開放)/NC (通常關閉) 介面。這可能是一個很好的解決方案, 控制設備不能直接控制的 Arduino 的數位 i/o。標準化的盾構因數使與 Arduino 和相容的平滑連接。盾構還有四 LED 指示燈, 顯示每個中繼的開/關狀態。
繼電器是有用的開關交流電器如風扇, 光, 電機或高電流直流執行器, 如電磁閥等。
注意: 在處理 AC 時要格外小心. 獲得認證電工的説明。
功能
Arduino/Seeeduino 盾相容
繼電器螺絲端子
每個中繼的工作狀態指示器
高品質繼電器
提供無/NC 介面
Channel1 介面
COM1-普通針
NC1-通常關閉。將與 COM1 連接時, RELAY1 針設置低, 並斷開時, RELAY1 高;
NO1-通常打開。當繼電器1引腳設置高並斷開時, 將與 COM1 連接, 當 RELAY1 低時;
4數位引腳控制4繼電器
RELAY1-RELAY4 引腳可以直接連接到 Arduino 引腳數 7-4, 因此, 四繼電器可以很容易地控制由 Arduino
