4 Channel Mechanical Relay Shield for Arduino UNO MEGA
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 smooth connection with the Arduino. The shield also has four dynamic indicators show the on/off state of each relay. No Hassle connection to Arduino UNO or MEGA.
Standardized shape design.
Working status indicators for each relay.
Provides NO/NC interfaces.
Operating at 5V, direct driven by a microcontroller pin.
Can switch ON and OFF 125V AC at 3 Amps max. Or 24V DC at 3 Amps
Note: please cover USB socked on Arduino board to prevent possible contact metalUSB interface casing with the bottom of this shield
Arduino UNO not included.
