This IoT 2-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 2 on-board DPDT relays. Six 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 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. DPDT Relays are available in 1, 3, and 5-Amp versions, customized when added to your shopping cart.
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.
