NI 9234 Operating Instructions and Specifications 22 ni.com
IEPE compliance voltage..................19 V max
If you are using an IEPE sensor, use the following equation to make
sure your configuration meets the IEPE compliance voltage range.
(Vcommon-mode + Vbias ± Vfull-scale) must be 0 to 19
Overvoltage protection (with respect to chassis ground)
For a signal source connected
to AI+ and AI–........................... ±30 V
For a low-impedance source
connected to AI+ and AI–..........– 6 to 30 V
Input delay................................... .....38.4/ fs + 3.2 μs
where Vcommon-mode is the common-mode voltage applied
to the NI9234
Vbias is the bias voltage of the IEPE sensor
Vfull-scale is the full-scale voltage of the IEPE sensor
