4-20 mA input cable

The 4-20 mA input cable (CABLE-4-20mA) measures current from 0 to 20.1 mA. Do not expose to current

above 20 mA or to negative current. Do not cut off the end of the gray cable where it connects to the blue and

yellow wires as it contains the precision resistor required for current measurement. The 4-20 mA input cable is

for use in indoor and outdoor environments.

Figure 5 shows a schematic of the 4-20 mA input cable.
