Relay Shield v3.0

Description

Description 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 For technical support, please post your questions to our forum .
