Placa Arduino com 4 canais de relés isolados

26,38 €



Informação do fabricante:

Rboard is a unique Arduino board which features 4 channels isolated relays, an XBee socket, and an ATMega328. This board will add relay control as well as wireless connectivity to your projects. It’s great for anything from home automation to robot control. The possibilities are endless!


  • 4 optocoupler isolated channels
  • 4 mechanical relays with status indicator LED
  • Both “NC” and “NO” ports for each relay
  • ATMega328P with XBee interface headers, Micro SD socket
  • With Arduino Duemilanove bootloader

PWR_EXT Setting

Rboard is designed for isolating industrial application with external power supply.  So when remove the jumpers on PWR_EXT, use the DC 7-20 terminal to for ATMega328 and all digital circuit power supply, and supply the 5V relay by the PWR_EXT terminal with 5V, there are 2 completely isolated power systems for  controller part and relay part.

If you don't need so stringent electrical isolation, put the jumpers on PWR_EXT, then you don't need an extra power supply, the relays will supply by the DC 7-20 terminal the same as controller part - but there also the opto-isolation between the relay and controller I/Os.


The RBoard does not have a USB con­nec­tion. So you need a USB/Serial adapter - we recommend the Foca FT232RL breakout board.
