Overview

Product overview

Key product information and technical features.

Designed for modular measurement systems, the NI-9232 operates in NI CompactDAQ or CompactRIO systems. Its dynamic signal acquisition architecture supports industrial sensor measurements.

Connector selection requires attention: NI identifies 782000-01 as the screw-terminal version and 784397-01 as the BNC version. The supplied catalog information references both 782000-01 and BNC connections, so the exact hardware variant remains unresolved.

  • Software-selectable AC or DC input coupling.
  • Selectable IEPE excitation of 0 or 4 mA.
  • Built-in anti-aliasing filters automatically track the sample rate.
  • IEPE open- and short-circuit detection.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the NI-9232 support smart TEDS sensors?

Yes. The datasheet specifies IEEE 1451.4 TEDS Class I support.

Does part number 782000-01 identify the BNC version?

No. NI lists 782000-01 with screw terminals; the BNC version is 784397-01. Confirm the module label and connectors because this catalog record contains conflicting variant information.
