Description

The Relay Shield is an Arduino compatible smart module with 4 mechanical relays providing an easy way to control high voltage.

The max switching power is 70W DC or 35V DC. It can be directly controlled by Arduino/Seeeduino through digital IOs with external 9V supply. With the XBee form socket and 315/433MHz RF module interface, the Relay shield can be remotely controlled, making it easy to use in robotics, industry control, smart houses etc.

Note: Take care the pins on the Shield should not be touched with USB connector of Arduino UNO when they are connected.

Features:

• Arduino/Seeeduino, Arduino Mega, and Seeeduino Mega compatible
• 4 mechanical relays with photo-coupled circuit
• Equipped with screw holes for easy installation
• Light weight
• Small form factor
• Native Arduino/Seeeduino compatibility
• Extendable
