Description
Analog Input Sense—In NRSE mode, the reference
for each AI <0..15> signal is AI SENSE; the
reference for each AI <16..31> signal is
AI SENSE 2; the reference for each AI <80..143> is
AI SENSE 3; and the reference for each
AI <144..207> is AI SENSE 4. Also refer to the
Connecting Ground-Referenced Signal Sources
section of Chapter 4, Analog
Analog Output Channels 0 to 3—These terminals
supply the voltage output of AO channels 0 to 3.
Analog Output Ground—AO GND is the
reference for AO <0..3>. All three ground
references—AI GND, AO GND, and D GND—are
connected on the device.
Digital Ground—D GND supplies the reference for
P0.<0..31>, PFI <0..15>/P1/P2, and +5 V. All three
ground references—AI GND, AO GND, and
D GND—are connected on the device.
Port 0 Digital I/O Channels 0 to 31—You can
individually configure each signal as an input or
output.
Analog Programmable Function Interface
Channels 0 to 1—Each APFI signal can be used as
AO external reference inputs for AO <0..3>, or as an
analog trigger input. APFI <0,1> are referenced to
AI GND when they are used as analog trigger inputs.
APFI <0,1> are referenced to AO GND when they
are used as AO external offset or reference inputs.
These functions are not available on all devices.
Refer to the device specifications.
+5 V Power Source—These terminals provide a
fused +5 V power source. Refer to the
Source section for more information.
