What this shield can do?

  • Work with any Arduino Nano
  • Work from 15-30 AC/DC.
  • Have 4x220v sensor
  • Have 4x8A switch relay
  • Have 0-10V output
  • Have two RS-485
  • 3 PT1000/pulled down analog input

Pin-out for auduio

  • D2,D3,D4 - TX,RX and RE/DE of 485
  • D11, D12, D13 - for second 485
  • D5 - PWM output for 0-10V
  • D6 - PWM output for second 0-10V
  • D7-D10 - control for switch relay 1-4
  • A4,A5,A6,A7 - pulled down input for PT1000
  • A0-A3 - sensors input
