One count in the specification table is equal to one least significant
bit of the analog data value (1 in 4096).
Note 1: Shields should be grounded at the signal source.
More than one external power supply can be used provided all the power supply commons are connected. A Series 217, 0.032A, fast-acting
fuse is recommended for 4-20 mA current loops. If the power supply common of an external power supply is not connected to 0 VDC on the
module, then the output of the external transmitter must be isolated. To avoid “ground loop” errors, recommended 4-20 mA transmitter types
are: 2 or 3 wire - Isolation between input signal and power supply or 4 wire - Isolation between input signal, power supply, and 4-20 mA
