  • 16 Relay board (one Bank) .PDF

Running(Edit)

for to run you need a six component:

  • Arduino mega
  • Arduino Ethernet shield
  • micro SD card
  • Main board
  • Power supply (5V to USB or up to 12V in DC plug)
  • Four relay board controlled by grounded input (Bank0-Bank3) - MAX +50V DC / 500 mA
    • Bank0 16 outputs
    • Bank1 16 outputs
    • Bank2 16 outputs
    • Bank3 15 outputs
  1. micro SD card no larger than ??GB, format at FAT16 and upload ascii file config.cfg with this content

Hardware(Edit)

Configure jumper(Edit)

  • JP1 - short disable auto reset from USB (must be open at upload firmware)
  • JP2 - short connect power between Arduino DC input and power on Relay board - WARNING to maximum voltage Arduino Mega

How to connect own relay(Edit)

Firmware(Edit)

For beginners Getting Started with Arduino

You can configure firmware from master tree GitHub

Or download preconfigured version

config.cfg copy to microSD card and plug to Ethernet shield

.ino file compile and upload to Arduino MEGA
