FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the NI 9924 a PXI Express data acquisition module?

No. The NI 9924 is a 25-pin D-SUB to screw-terminal connector block for C Series modules, not a PXI Express acquisition module.

Can the NI 9924 be used with the NI 9201 or NI 9221?

Yes. NI recommends it for the 25-pin D-SUB versions of both modules. Confirm that your module has that connector variant.

What wire size does the NI 9924 accept?

The guide specifies 16–26 AWG copper conductor wire, with 4.5 mm of insulation removed and a maximum terminal tightening torque of 0.4 N·m.
