This IoT 8-channel DPDT relay controller was designed to function as a shield for today’s most popular IoT communication modules, including Particle Photon, Electron, Bluz, Arduino, and many more. On-board DPDT relays are ideally suited for control of telecommunications, audio, and other low-power switching applications. Each DPDT relay contains two separate switches that switch simultaneously with 6 connections for each relay. DPDT Relays are available in 1, 3, or 5-Amp versions, customized when added to your shopping cart.
This controller is based on the MCP23008, a common I2C interface chip for GPIO applications. In this design, the GPIO port is used to control the onboard DPDT relays. Three on-board address jumpers allow up to 8 similar devices (based on the MCP23008 or MCP23017) to be chained to the same I2C bus for individual control. 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 relay is accessible to the user via screw terminals, capable of accepting 14 AWG wires.
Leverage the power of IFTTT.com and Particle services to do almost anything. Send a tweet if someone rings your doorbell, send a notification to your phone if someone opens a door, turn on almost anything right from your phone with a simple setup, the possibilities are endless. NCD provides this controller with an optional pre-programmed Particle Photon module for easy connection to IFTTT. No programming required! Just use the simple IFTTT interface to set up your different configurations.

What is the NCD IoT Interface?
The NCD IoT Interface provides users with a means of changing or upgrading the IoT communications technology as new technologies emerge. The NCD IoT Interface is directly compatible with Particle Photon for WiFi communications, Electron for Cellular Communications, Bluz for Bluetooth. Optionally, adapters may be installed to provide a direct interface to Arduino Nano, Micro, USB, PyCom WyPy, Onion Omega, Raspberry Pi, and much more. The NCD IoT interface allows you to re-use your hardware so it never becomes obsolete! Based on I2C communications, the NCD IoT Interface uses only 2 GPIO lines of your microcontroller, freeing the rest of your CPU for other tasks.
