    seeedstudio - Relay Shield v3.0 - DIY Maker Open Source BOOOLE

    • Item #: 9SIVAMDJPC3768
    • Mfr. Part #: 103030009
    • The Relay Shield utilizes four high quality relays and provides NO/NC interfaces that control the load of high current. Which means it could be a nice solution for controlling devices that couldn¡¯t be directly controlled by Arduino¡¯s Digital I/Os. Standardized shield form factor enables smoothly connection with the Arduino. The shield also has four dynamic indicators show the on/off state of each relay.
    • Features:
    • Arduino/Seeeduino compatible
    • Standardized shape design
    • Working status indicators for each relay
    • High quality relays
    • Provides NO/NC interfaces
    • Specification:
    • 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 contro
