Overview

Product overview

Key product information and technical features.

Each NI-9222 input has an independent signal path and ADC, allowing all four channels to be sampled simultaneously rather than through a shared multiplexed converter.

Sampling limits depend on the acquisition environment: CompactDAQ with NI-DAQmx and CompactRIO FPGA User-Controlled I/O Sampling support 500 kS/s, while CompactRIO FPGA I/O Nodes are limited to 300 kS/s.

Independent ADCs support simultaneous acquisition across all four inputs.
Successive approximation register (SAR) conversion with 16-bit resolution.
Input impedance greater than 1 GΩ.
±30 V input overvoltage protection.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the NI-9222 sample all channels simultaneously?

Yes. Each input has its own ADC and independent signal path.

Is this catalog unit the BNC version?

The connector is not confirmed. The legacy description says BNC, but the catalog tag identifies 781397-01, which NI lists as the screw-terminal version. Verify the unit label and connector before choosing accessories.
