The NI 6351/6353 are NI X Series Analog Input Cards with 16-bit resolution, a maximum sample rate of 1.25 MS/s, and 50 ppm of sample rate accuracy. The cards support multiple input ranges and have a maximum working voltage of ±11 V.
The NI 6351/6353 family provides high‑performance data acquisition for PCIe and USB platforms. Both devices offer flexible analog input configurations, high‑resolution analog output, and extensive digital I/O, making them suitable for a wide range of measurement and control applications.
Key specifications include up to 1.25 MS/s single‑channel sampling, 16‑bit ADC resolution, configurable input ranges from ±0.1 V to ±10 V, and a variety of digital I/O and counter/timer resources. Power requirements, environmental limits, and safety certifications are also detailed for proper system integration.
