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.
Arduino/Seeeduino Shield compatible
Relay screw terminals
Working status indicators for each relay
High quality relays
Provides NO/NC interfaces
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

Relay Shield v3.0
The Relay Shield provides a solution for controlling high current devices that cannot be controlled by Arduino’s Digital I/O pins due to current and voltage limits.
Just to confirm...the relays will work with 120VAC correct? Also, I assume this a fits the Arduino Uno Rev3?Question by: admin on 2018-12-18 02:29:58
So I just looked at a close up of the relays in the pic and answered half my question. ;) Now just need to make sure it works with an Uno Rev3 board.Answer by: admin on 2018-12-18 02:29:58
