Overview

Product overview

Key product information and technical features.

High-resolution mode provides 50/60 Hz rejection for low-frequency noise reduction. For faster acquisition, high-speed mode uses a 2 ms conversion time per channel; channels are scanned rather than sampled simultaneously.

16 analog current input channels in a C Series module.
24-bit delta-sigma analog-to-digital conversion.
Selectable high-speed and high-resolution conversion modes.
High-resolution mode includes 50/60 Hz noise rejection.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the NI 9208 an analog output module?

No. NI identifies it as a 16-channel C Series current input module with 24-bit resolution.

Does the NI 9208 sample all channels simultaneously?

No. It uses scanned acquisition. Conversion time is 2 ms per channel in high-speed mode and 52 ms per channel in high-resolution mode.

Which connector corresponds to part number 780968-01?

NI lists 780968-01 as the D-SUB current input module. Verify the physical module label because the NI 9208 family also includes a spring-terminal version.
