AI channel Module

[KRAZE4LV]

I am using M-sreies PXI-DAQ-6251. Recently I am doing a Project where I need more than 16 AI Channels. But NI 6251 consist of maximum 16 channels, Is there a Card or module which I can attach with NI 6251 to provide me with extra AI channels. Previously, I wanted to have more AO channels so I bought NI PXI 6704 for adding more channels to the DAQ NI 6251.

Is there any such module which gives more channels?

The 6704 does not add channels to the 6251. It is a separate card. You can do the same thing by getting another 6251, any other multi-function card, or SCXI.

Hello KRAZ4LVE, hope you are doing great, 

Seems that you ran out of channels in your DAQ card.

When you attached the NI 6704 card to your system you increased the number of AO by adding a different PXI card, you will have to do add another AI card to your system in order to have more Analog Input channels, 

You can check our website for more options or simply buy another NI-PXI-6251.
