Relay Shield V3 for Arduino

Description Arduino/Seeeduino compatible Standardized shape design Working status indicators for each relay High quality relays Provides NO/NC interfaces The Relay Shield V3 for Arduino 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.

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 can be connected directly with Arduino pin number of 7-4, so that four relays could be easily controlled by the Arduino
