AIDIPI_06 is configured as a current input and is shown connected to an external current
source.
Pin 5 is the ISO_GND connection for AIDIPIs 1 through 4; Pin 10 is the ISO_GND
connection for AIDIPIs 5 through 8. Pins 5 and 10 are internally connected together.
Unconnected analog inputs report an alarm condition.

Alternatively, you can use loop power as shown in
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).
