PR15-7

This I2C 32-channel Solid-State relay controller offers a cross-platform solution with unmatched compatibility and expansion capabilities. Compatible with every IoT technology that supports I2C communications, this is the most versatile relay controller we have ever manufactured. All NCD I2C relay controllers have a I2C output, allowing you to chain together more relay controllers, a vast array of sensors, current monitors, PWM drivers, and much more. The expansion abilities of this relay board are unmatched by any other manufacturer in the world. This controller is based on dual MCP23017 controllers, a common I2C interface chip for GPIO applications. In this design, the GPIO port is used to control solid state relays. The I2C bus support up to 8 similar devices (based on the MCP23008 or MCP23017). This controller counts as two devices on the I2C bus. Two on-board address jumpers set the I2C start address of both MCP23017 interface chips. On-board status LEDs display the on/off status of each relay. This controller may be powered using our optional power supply or with 12VDC and direct screw terminal connection of bare power wires. Each solid state relay is accessible to the user via two large screw terminals, capable of accepting 12 AWG wire. This controller includes many solid-state relay options, customized when added to your shopping cart.
