In industrial environments 4-20mA is a commonly used range of values for a current loop where 4mA represents the lowest value and 20mA indicates the maximum. Some advantages compared to sending a voltage is that the resistance of the cable doesn't affect accuracy and devices may be powered from the same pair of wires.

4-20 mA PID controller PCB layout
I have designed a 4-20 mA PID controller using an ATmega328P, an MCP4922 (DAC), and an XTR115UA (4-20 mA current loop transmitter).
I used the circuits proposed in the datasheets and the PCB and schem …
