  • NI-9205

Issue Details

Does the overvoltage protection on the NI 9205 Module work differently if the wiring configuration is either Referenced Single-Ended or Differential.

Solution

According to the NI 9205 Datasheet the overvoltage protection for the NI 9205 Module is +/- 30 V for one channel only. This means the following for each wiring configuration:
  • Referenced Single-Ended: the voltage cannot exceed the +/- 30 V between AI+ and COM.
  • Differential: the voltage cannot exceed the +/- 30 V between AI+ and AI-.
