Hardware

  • PXIe-2727
  • PXI Programmable Resistor Module

Issue Details

I'm looking at the PXIe-2727 programmable resistor module and it lists a maximum of 16 kOhm resistance. Can I add up several channels to increase that resistance?

Solution

Yes, you can add the resistance of several channels in series to increase the total maximum resistance.

The only caveat is that you should always keep in mind the maximum voltage, current and power each channel can withstand.

Additional Information

The 272x reference VI API doesn't include this configuration but you can develop your own application with your own calculations by understanding the resistance of each relay and which paths you need to close. Refer to your device documentation for further information.
