Description
The NI-9244 is a C Series Analog Input module, detailed under part number 783106-01, designed for high-voltage, three-phase applications. It features a 400VRMS L-N (line-to-neutral) three-phase analog input, making it an ideal choice for a wide range of measurement applications.
This module is equipped with 24-bit Delta-Sigma ADCs for each channel, ensuring high precision in measurements. It supports three single-ended, simultaneously sampled analog input (AI) channels, allowing for efficient data acquisition. With a sampling rate of 50 kS/s per channel, it captures fast-changing signals with ease.
The NI-9244 offers an input range of up to 800 Vrms L-L (line-to-line), catering to applications requiring high voltage input. Its connectivity is facilitated through a screw-terminal setup, providing a secure and reliable connection. The maximum input noise is limited to 6 mVrms, ensuring signal integrity.
This module features DC input coupling and an input impedance of 2 MΩ Neutral-to-Ground, AIx-to-Ground, designed to accommodate a wide range of sensor types. It also boasts overvoltage protection of up to 800 Vrms continuous, with a peak of 1000 Vrms for 1 second, safeguarding the module against unexpected voltage spikes.
Regarding durability, the NI-9244 is capable of withstanding voltage surges of up to 8 kV for 1.2 µs/50 µs, ensuring long-term reliability even in harsh electrical environments. It is compatible with various software, including LabVIEW, LabWindows/CVI, ANSI C, and .NET, offering flexibility in application development.
The power consumption of the module is 332 mW max when active, and drops significantly to 50 µW in sleep mode, highlighting its efficiency. Weighing in at 5.3 oz, it is
