4-20mA Signal Shield for Arduino

With this arduino shield you’ll be able to connect to any industrial sensor, monitor, and even control a variable directly from you Arduino board!


The Arduino 4-20mA  with real time clock shield is a 4-20mA current signal adaptation board. This Shield has 4 input channels which allow converting signals that come with this industrial standard.

The 4-20mA Shield has a DS1307 Real Time Clock that attaches a time stamp to all converted data. The RTC has a backup power supply that uses 12mm batteries (not included).

The Shield works with type 2, 3 and 4 Current Transmitters, and can be connected to other platforms such as Uno and Mega. For correct operation, you need a 9-12VDC external power supply.


Arduino uses Analog pins 0, 1, 2, 3, SDA, SCL and RESET for current signal converting and RTC communication. As long as you use this Shield, these pins cannot be used for other purposes.

This board include stackable header pins to be soldered for Arduino connection.

12mm CMOS batteries required for RTC (not included)
