NI 9219 vs NI 9229

[brethigh]

Hey there, me again!

I'm trying to expand on my current test stand with modules I already have on hand.  I've been using a 9229 module to record voltage, current, and torque for a 48V electric motor under load.  I've been asked to also record the voltage and current of the 3 phases.  I only have one 9229 module but I have four 9219 modules.  The engineer wants to be able to record at 1,000 Hz, and the voltage will be going up to 56V at times.  I understand the wiring would be somewhat different on the 9219 than the 9229, but I'm more concerned about can it physically do this.  The 9219 has five different nominal voltage ranges listed in the datasheet, and also says that it can only do 50S/s/ch.  Is that only 50 Hz?  I'd really love to be able to use the 9219s since I have so many of them.

Hi Brethigh,

your question would be better suited for the Multi function DAQ board: https://forums.ni.com/t5/Multifunction-DAQ/bd-p/250 since this board is for FlexLogger.

You are correct, the 9219 cannot go over 50 Hz/ch.

For power measurement, ideally you want to have synchronous acquisition. Some good options would be the : 9225, 9242 or 9244

best of luck,

Ah yes, I forgot to change out of the FlexLogger area.  Thanks for pointing that out.  And thanks for the answers, I just needed confirmation before asking to purchase another module.
