Issue Details

I am looking for the maximum amount of current that an Analog Input (AI) can handle for the USB-6008/6009.


  • The maximum analog input for overvoltage protection on the 6008/6009 is 35 V.
  • The input impedance for the 6008/6009 is 144 kΩ.
  • This would imply that the maximum input current during overvoltage conditions is 0.243 mA per analog input channel.
