Arduino 4-20mA Shield

Hi All,

My group just came out with a 4-20mA shield for the Arduino. You can find the web-page here: http://www.erdosmiller.com/products/arduino-4-20ma-shield

  • 4 4-20mA shield inputs. (2-wire,3-wire,4-wire compatible)
  • Buffered ADC inputs.
  • High resolution external ADC with internal reference.
  • Also works with the built in Arduino ADCs.
  • There is also a switching regulator on the board so that the Arduino can be powered from 10-36V.
  • Use the shield in a "pass-thru" configuration or as a 4-20mA sensor endpoints.

Can your group come up with a shield that will mimic 4-20mA output? I'm looking for a solution to transmit 4-20mA signal, not receive it.
