2-Channel Relay Controller for I2C

  • MCP23008 I2C Controlled Mechanical Relays
  • Six Programmable Digital I/O
  • 1.7 MHz Communication Speed
  • Sale
  • Regular price $29.95

Description

The MCP23008 Port Expander (from Microchip) offers an excellent platform for I2C relay control.

This 2-channel relay controller dedicates 2 MCP23008 Digital I/O Pins to relay control while offering the remaining 6 Digital I/O pins for external use. This I2C relay controller makes it easy to expand its capabilities with an integrated I2C expansion port.

Use any of our I2C Mini Modules to expand the capabilities of this controller to include a wide range of sensors, more relays, or any other I2C device we make in the future!

Operates on 12VDC using a 2.1mm barrel connector (center positive) or 2-wire terminal block.
