I have a USB-9233 acquisition unit. The unit acquisition channels have IEPE current.

How to turn off the IEPE current for the USB-9233 unit.

"The USB-9233 IEPE excitation current and
AC coupling are always enabled."

Basically, the IEPE excitation is built into the circuit.  You CANNOT shut if off on these modules.

Initiatives have been taken in R&D to develop new modules with other options, but at this time, we do not have one released. But stay tuned

Thanks,
