Overview

Product overview

Key product information and technical features.

The NI-9201 adds eight voltage measurement channels to a C Series system. Its aggregate scanning rate is shared across the acquired channels rather than specified per channel.

Screw-terminal, spring-terminal, and DSUB versions exist. Connector selection also affects the channel-to-earth isolation rating, so the physical variant must be established before selecting wiring or applying safety limits.

  • Eight single-ended voltage inputs with no differential input channels.
  • 12-bit successive approximation register ADC.
  • ±100 V channel-to-COM overvoltage protection; measurement range remains ±10 V.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does part number 779372-01 identify the screw-terminal version?

No. NI identifies 779372-01 as DSUB and 779013-01 as screw terminal. This catalog record contains conflicting variant information that requires confirmation.
