ternatively, you can use loop power as shown in Figure 3-2. In the figure, AIDIPI_08 is
shown connected to an external current source.
The current source is powered by the 24V loop supply which can power up to 8 field
devices (4-20mA or 1-5V). To create the correct ground reference, connect the 24V loop
GND (pin 20) externally to ISO_GND (in this case pin 10).
