Description
The NI-9244 is a high-precision C Series Voltage Input Module with the part number 783106-01. This module is designed for a wide range of applications, providing accurate voltage measurements through its advanced features.
Each of the three single-ended, simultaneously sampled AI channels utilizes a 24-bit Delta-Sigma ADC per channel, ensuring high-resolution data acquisition. The module boasts an impressive sampling rate of 50 kS/s per channel, allowing for the capture of fast transient signals without loss of detail.
The NI-9244 is capable of handling high voltage levels with an analog input range of up to 800 Vrms L-L, making it suitable for industrial applications. Additionally, the module is equipped with screw-terminal connectivity for easy installation and secure connections.
Despite its high performance, the module maintains a low maximum input noise of 6 mVrms, ensuring accurate and reliable measurements. The DC input coupling and high input impedance of 2 MΩ further contribute to its precision and versatility.
For safety, the NI-9244 is designed with robust overvoltage protection, capable of withstanding up to 800 Vrms continuously, and up to 1000 Vrms for 1 second. It also features a voltage surge withstand capability of 8 kV for 1.2 µs/50 µs, protecting the module from sudden voltage spikes.
Software compatibility is broad, supporting NI-DAQmx, LabVIEW, LabWindows/CVI, ANSI C, and .NET, offering flexibility in programming environments for data analysis and system integration. The power consumption of the NI-9244 is optimized for efficiency, requiring only 332 mW in active mode and dropping to a mere 50 µW in sleep mode.
In summary, the NI-9244 is a technologically advanced, highly reliable voltage input module that provides precise measurements, robust protection, and
