Description
AI GND

Analog Input Ground—These terminals are the input bias
current return point. AI GND and AO GND are connected on
the device.
Note: AI GND and AO GND are isolated from earth ground,
chassis ground, P0.GND, and P1.GND.
AI <0..7>±
AI GND
Input
Analog Input Channels 0 to 7±—AI 0+ and AI 0– are the
positive and negative inputs of differential analog input
channel 0. Similarly, the following signal pairs also form
differential input channels:
Also refer to the
Analog Input Ground-Reference Settings
section of Chapter 4,
Note: AI <0..7>± are isolated from earth ground and chassis
ground.
AO <0..1>
AO GND
Output
Analog Output Channels 0 to 1—These terminals supply the
current output of AO channels 0 to 1.
Note: AO <0..1> are isolated from earth ground and chassis
ground.
