DAQ with Analog Voltage Inputs and Analog Current Outputs

[MrPibb97]

Hi Everyone,

I'm looking for a DAQ that is capable of simultaneously measuring at least 3 analog voltage input signals and outputting at least 3 analog current signals with a range of 0-20mA. Basically I'm inputting a voltage signal and I want the DAQ to output a current signal. I've searched high and low and cannot seem to find a model capable of this.

Thanks,

You will probably have to look at using a CompactDAQ chassis and getting a couple of C series modules for your I/O.  I did find a PCI-6704 card, but it is only an output card (voltage and current).

Look here for modules:

Or try the advisor to build a system

Another option is to call your local rep and get recommendations. 

Or look into buying/making a voltage to current converter.  It looks like there are some PCI/PCIe cards that have 4 analog output channels that you could use.  It will also depend on how much you have to sped on your system.

What form factor are you looking for? You could easily use a cDAQ to do 3 simultaneous AI channels and 3 current output channels. For voltage input, you could use the NI 9201 or 9215. For current output, you would use the NI 9265 or 9266. Any 4-slot cDAQ chassis would work, such as the cDAQ-9174, cDAQ-9184, or cDAQ-9185.

I believe the only PCI/PXI options that NI has for current output is the PCI- or PXI-6704 and the PXIe-4322, although these cards don't have any voltage input channels.
