This IoT 4-channel high-power relay controller is capable of hosting many types of IoT communication modules, including Particle Photon, Electron, Arduino, and more. On-board relays are ideally suited for control of high power loads up to an absolute maximum of 30 Amps at 240VAC, depending on the relay chosen during purchase. This design is suitable for some mildly inductive loads when used with external induction suppression capacitors, but focuses primarily on resistive load switching. This controller includes 20-Amp SPDT or 30-Amp SPST relays, 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 4 onboard SPDT relays. Four 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.
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.
