Overview

Product overview

Key product information and technical features.

The NI-9250 measures voltage signals from IEPE and non-IEPE sensors, including accelerometers and microphones. It supports smart TEDS sensors and provides 2 mA IEPE excitation.

This C Series module combines BNC front connections and AC/DC input coupling with simultaneous channel measurement. Built-in anti-aliasing filters adjust to the sample rate.

Two analog input channels with simultaneous sampling.
±5 V input range and up to 102.4 kS/s per channel.
24-bit resolution and 108 dBFS DSA dynamic range.
BNC front connections and a C Series bus interface.
2 mA IEPE excitation for supported sensor measurements.
AC/DC input coupling with a listed highpass filter cut-off frequency of 0.43 Hz.
Operating temperature range of -40 °C to 70 °C.
