NI 9232 Operating Instructions and Specifications
If you are using an IEPE sensor, use the following equation to
make sure your configuration meets the IEPE compliance voltage
range.

Short circuit ................................ V AI < 1.5 V
Open loop ................................... V AI > 24 V
Overvoltage protection
For a low impedance source
connected between any
two terminals .............................. ±45 V
where
V
common-mode
is the channel-to-channel common-mode
voltage across two or more NI 9232 channels
V
bias
is the bias voltage of the IEPE sensor
V
full-scale
is the full-scale voltage of the IEPE sensor
