Relay Shield v3.0 4路繼電器擴展板
Relay Shield v3.0 4路繼電器擴展板 提供四個高品質的繼電器，可控制大電流負載的Arduino / Seeeduino板。它還提供NO（常開）/ NC（常閉）界面。對於不能直接由Arduino的數字I / O控制的設備，這可能是一個很好的解決方案。標準化的屏蔽外形使得能夠與Arduino和兼容設備保持良好的連接。屏蔽層還有四個LED指示燈來顯示每個繼電器的開/關狀態。
繼電器可用於開啟/關閉風扇，燈光，電機等交流電器或電磁閥等大電流直流執行器。
注意：處理AC時要格外小心。從認證的電工獲得幫助。
特徵
Arduino / Seeeduino Shield兼容
繼電器螺絲端子
每個繼電器的工作狀態指示器
高品質的繼電器
提供NO / NC接口
Channel1接口
COM1 – 公共引腳
NC1 – 常閉。當RELAY1引腳設置為低電平時將連接COM1，當RELAY1為高電平時斷開;
NO1 – 常開。當繼電器1引腳設置為高電平時，將與COM1連接，當RELAY1為低電平時斷開;
4個數字引腳來控制4個繼電器
RELAY1-RELAY4引腳可以直接與Arduino引腳號7-4連接，這樣四個繼電器可以很容易地由Arduino控制

官方技術文件與範例
The Relay 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
