Description
This IoT 24-channel Solid-State relay controller was designed to host many different IoT communication modules, including Particle Photon, Electron, Bluz, Arduino, and many more. 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 24 solid state relays. Eight programmable Digital Input/Output port pins are also available via screw terminals for use in Contact Closure detection applications or monitor and control external TTL circuits. 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 onboard 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 wires. This controller includes many solid-state relay options, customized when added to your shopping cart.
IFTTT
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.
Powered By Particle
Give your Particle Photon the power to interact with the real world in ways never before possible. Use the optional Particle Photon module pre-flashed with our custom IFTTT firmware, NCD compatible shields allow for control of many types of relays, monitoring digital and analog sensors, and much much more. Chain I²C accessory boards to your system to add whatever you may need for your next control and automation project.
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.
