This 4-Channel I2C Relay controller makes it easy to control relays using the integrated MCP23008 Digital I/O Port Expander.
4 programmable digital I/O lines are also available for use in external digital logic applications.
Integrated I2C expansion port makes it easy to add any of our I2C devices with a convenient 4-Pin plug interface.
Operates on +12VDC using a 2.1mm barrel connector (center positive) or 2-wire terminal block.
This is a general purpose I²C device compatible with all computing platforms and IoT technologies, including Raspberry Pi, BeagleBone, Arduino, Particle, BridgeX5, and many more. All ControlEverything.com devices support a strict +5V I²C Bus standard.
