Overview

Product overview

Key product information and technical features.

The NI-9223 provides high-speed differential voltage acquisition within the NI C Series ecosystem. Its simultaneous acquisition architecture supports measurements that require samples from multiple channels at the same instant.

NI identifies ballistics, impact and blast wave testing as applications for this module. It also supports mixed-measurement systems in which the NI-9223 runs at its maximum sample rate while an adjacent module samples more slowly.

Four differential voltage inputs with simultaneous sampling.
Up to 1 MS/s per channel with 16-bit resolution.
±10 V analog input range.
60 VDC continuous isolation between channels and from channels to earth ground, Measurement Category I.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the 1 MS/s sample rate shared across the four inputs?

No. The NI-9223 supports up to 1 MS/s per channel with simultaneous sampling.

Which NI-9223 part number uses BNC connectors?

NI identifies 783284-01 as the four-BNC version and 781398-01 as the screw-terminal version. This record contains conflicting legacy connector information, so its exact variant requires confirmation.

Are external bias resistors required for floating signal sources?

NI states that the NI-9223 does not require bias resistors; the source can connect directly to the analog input channel. Follow the module's getting started guide for wiring and safety limits.
