Overview

Product overview

Key product information and technical features.

Four per-channel programmable ranges support voltage measurements from ±200 mV to ±10 V. Channel-to-earth isolation permits monitoring cell banks elevated above earth potential without making the individual inputs high-voltage measurement channels.

Inputs share a common reference and multiplexed ADC; acquisition is not simultaneous. The module integrates into CompactDAQ or CompactRIO systems.

  • Selectable single-ended and differential input configurations.
  • Individually programmable voltage ranges.
  • Channel-to-earth isolation rated 600 VDC in the U.S. and 400 VDC in Europe, Measurement Category I.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the NI 9206 sample all channels simultaneously?

No. It uses multiplexed acquisition, and 250 kS/s is the aggregate rate, not a per-channel rate.

Does this model use a DSUB connector?

No. NI specifies spring-terminal connectivity for the NI 9206.

What is the NI part number?

NI lists 779526-01 for the NI 9206.
