1-Channel DPDT Signal Relay Shield + 7 GPIO with IoT Interface

This IoT 1-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. The DPDT relay on this controller contains two separate switches that switch simultaneously with 6 connection points.

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 a DPDT relay.  Seven 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.  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 LED displays the on/off status of the relay.  This controller may be powered using our optional power supply or with 12VDC and direct screw terminal connection of bare power wires.  The on-board relay is accessible to the user via screw terminals, capable of accepting 14 AWG wire.

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 simple setup, the possibilities are endless.  NCD provides this controller with a pre-programmed Particle Photon module for easy connection to IFTTT.  No programming required!  Just use the simple IFTTT interface to setup your different configurations.

Powered By Particle

Give your Particle Photon the power to interact with the real world in ways never before possible.  Complete with a 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.

Unlimited I2C Expansion

Based on our plug-and-play I2C interface standard, all NCD IoT devices are equipped with a I2C expansion port, making it easy to expand to a wide variety of sensors, current monitors, relay controllers, PWM controllers, and much more!  We are always designing new expansions for our plug-and-play I2C framework.  We are dedicated to building a product line of interconnected devices to simplify all forms of automation.  Re-use or upgrade your hardware in seconds by selecting the modules that best fit your needs, and chaining them together using the included I2C expansion cables!

1-Amp DPDT Signal Relay Option

This controller offers an optional 1-Amp small signal relay, allowing control of low-power telecommunications signals up to 12VDC at 1 Amp. Ideal for audio, telecommunications, and very low power switching applications. This relay has a low On resistance. The 1-Amp signal relay is of the DPDT variety, which is the same as two SPDT relays that switch simultaneously, but remain isolated from each other. This relay has 6 total user connections, two of each of the following: Common (C), Normally Open (NO), and Normally Closed (NC). Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. All connections are made via screw terminals, capable of accepting up to 16 AWG wire.

3-Amp DPDT Signal Relay Option

This controller offers an optional 3-Amp small signal relay, allowing control of low-power telecommunications signals up to 12VDC at 3 Amps. Ideal for audio, telecommunications, and very low power switching applications. This relay has a low On resistance. The 3-Amp signal relay is of the DPDT variety, which is the same as two SPDT relays that switch simultaneously, but remain isolated from each other. This relay has 6 total user connections, two of each of the following: Common (C), Normally Open (NO), and Normally Closed (NC). Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. All connections are made via screw terminals, capable of accepting up to 14 AWG wire.

5-Amp DPDT Signal Relay Option

This controller offers an optional 5-Amp signal relay, allowing control of  signals up to 12VDC at 5 Amps. Ideal for audio, telecommunications, and light-duty power switching applications. This relay has a low On resistance. The 5-Amp signal relay is of the DPDT variety, which is the same as two SPDT relays that switch simultaneously, but remain isolated from each other. This relay has 6 total user connections, two of each of the following: Common (C), Normally Open (NO), and Normally Closed (NC). Common is connected to NC when the relay is off.
