聖誕樹禮物

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?ˉt be directly controlled by Arduino?ˉs 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 controlled by the Arduino
