Accelerometer and cRIO module NI9232

[lillebc]

I have a NI9232 module in my cRIO setup and I would like to measure vibration with an accelerometer. Can I forexample use a Wilcoxon Research model ED-786A (teds support) and connect it directly to the module with IEPE exitation activated? Or do I need an external power source in addtion?

Thanks for your question,

Yes - the 9232 provides IEPE, which is turned on with a I/O node method or property in LabVIEW FPGA.

Ok, so no external power supply will be needed?

the NI9232 can provide the following?

Constant Power supply IB

4 mA

Min. 2 mA / Max. 10 mA

polarised untill

Voltage supply UB

+ 24 V

Min.+ 18 VDC/ Max.+ 30 VDC
