Chapter 2 Analog Input

Table 2-5 shows how signals are routed to the NI-PGIA.

Reference all signals to ground either at the source or at the DAQ device. If

you have a floating source, reference the signal to ground by using RSE

mode or DIFF mode with bias resistors. Refer to the

Differential

Connections for Non-Referenced or Floating Signal Sources section for

more information. If you have a grounded source, do not reference the

signal to AI GND. You can avoid this reference by using DIFF or NRSE

input modes.

Caution Exceeding the DIFF and common-mode input ranges distorts the input signals.

Exceeding the maximum input voltage rating can damage the device and the computer. NI

is not liable for any damage resulting from such signal connections. The maximum input

voltage ratings are listed in the specifications document for each E Series family.

(NI 6031E, NI 6033E, and NI 6071E Only) For these extended AI devices, the AI

signals are AI <0..63>, AI SENSE, AI SENSE 2, and AI GND. In

single-ended mode, signals connected to AI <0..63> are routed to the

positive input of the PGIA. In differential mode, signals connected to

AI <0..7, 16..23, 32..39, 48..55> are routed to the positive input of the

PGIA, and signals connected to AI <8..15, 24..31, 40..47, 56..63> are

routed to the negative input of the PGIA.

(NI 6013/6014 Only) These devices do not support RSE mode. To measure

single-ended signals relative to AI GND, connect AI SENSE to AI GND on

your accessory and use NRSE mode.
