THE PARTICLE PHOTON 8 CHANNEL RELAY SHIELD IS PERFECT FOR AUTOMATING YOUR PROJECTS OR CONTROLLING THEM OVER THE INTERNET!

Description:

The Particle Photon 8 Channel Relay Shield was developed so that anyone could dive right into the IoT world. It can be used to control lights, motors, solenoids, and many other electrical items. The Blynk App can be used to create an app for easy control right on your phone. It has 8 relays on board that are controlled independently by the digital I/O pins that are used to switch the relays on or off based on the state of the digital pin (HIGH or LOW). The remaining analog I/O pins are broken out to screw terminal blocks for easy access. Each relay has its own 3-postion screw terminal labeled, NO, C, or NC, for Normally Open, Common, or Normally Closed respectively. Each relays contact current rating is 10 amps and switching voltage rating is 277 Vac and 24Vdc max. Power can be supplied to the board by either the 2.1mm barrel jack connector that is found on the Arduino Uno, or the 2-postion screw terminal. The recommended supply voltage is 12Vdc for the board, with an amperage of at least 3 amps.

Addon Options:

Temperature Controlled Automatic Fan Circuit Option

This option has all of the above specifications as well as a temperature controlled fan circuit to improve cooling when the relay shield is being used under heavy load or operating in a high temperature environment. Temperature is measured using a 10K NTC thermistor. This temperature is used to turn the fan on or off based on the temperature of the voltage regulator.

Fan Option

There is a fan option available for purchase. A fan mount can be purchased with it or it can be mounted to the enclosure. If you did not purchase the fan circuit addon feature it is recommended to purchase the heatsink addon to provide some passive cooling to the voltage regulator.

Fans Specifications

• Fan manufacturer: CUI Devices
• Fan Size: Square 60mm
• Fan Thickness: 15mm
• Fan Airflow: 30.4 CFM
• Fan Voltage: 12Vdc
• Fan Power Rating: 213 mA
• 2 wire leads

Heat Sink Option

This option adds a heatsink to the voltage regulator (U15) that supplies the 5V plane on the board. This plane provides power to the relays and fan controller. The heatsink will passively help keep the voltage regulator cool by conducting the heat and passing it to the environment. Pairing the heatsink with a fan will greatly improve the cooling performance of the heat sink and extend the life of the voltage regulator.

NOTE:

It is highly recommended that if all the relays will be on for an extended period of time that cooling be provided to the board to avoid overheating and damaging the power supply circuit. This can be done by ordering the cooling fan control circuit version, heat sink, and fan. Or supply your own provisions for keeping the board cool.
