Specifications for Maximum Signal Ratings for AT Series Devices

If any signal should fall outside of the specified limits for any of the input
signals, do not connect it to the DAQ device. Before proceeding, add
signal-conditioning circuitry to the signal in question to either attenuate
or clip the voltage signal.
If dynamic (for example, AC) signals are connected to the inputs, you must
anticipate or calculate the maximum voltage that the signal may attain.
Again, if you suspect it will exceed the maximum signal rating allowed for
the selected signal, you should add protection or signal-conditioning
circuitry to prevent damage to the DAQ device and computer.
