Tech note
Connecting a 4-20mA to an external input

The 4-20mA cable (CABLE-4-20mA) measures currents from 0 to 20.1mA. The cable must be connected such that the current flows through, and with the proper polarity, as shown in the diagram. (Do not expose to current above 20mA or negative current.) Do not cut off the end of the gray cable where it connects to the blue and yellow wires, as this contains the precision resistor required for current measurements.
