NOTE 1: Shields should be grounded at the signal source.
NOTE 2: Unused channels should be connected to 0V
or have current jumpers installed.

typical)
More than one external power supply can be used (see channel 8).
If the power supply common of an external power supply is not connected to 0V on the
module, then the output of the external transmitter must be isolated. To avoid "ground loop"
errors, recommended 4–20mA transmitter types are:
2 or 3 wire: Isolation between input signal and power supply.
4 wire: Isolation between input signal, power supply, and 4–20mA output.
