Description
The National Instruments NI-9244 with part number 783106-01 is equipped with a high-precision 24-bit Delta-Sigma ADC per channel and supports three single-ended, simultaneously sampled AI channels. With an impressive sample rate of 50 kS/s per channel and a substantial analog input range of 800 Vrms L-L, this module ensures accurate and expansive data acquisition capabilities.
Designed for reliable connectivity, the module features screw-terminal connections and boasts a maximum input noise of 6 mVrms. It incorporates both digital and analog filters for signal clarity, and supports DC input coupling to accommodate a variety of measurement needs.
With an input impedance of 2 MΩ for both Neutral-to-Ground and AIx-to-Ground, the NI-9244 ensures compatibility with a range of signal sources. It also provides robust protection against electrical stress with 800 Vrms continuous overvoltage protection, capable of handling up to 1000 Vrms for 1 second, and can withstand voltage surges of 8 kV for 1.2 µs/50 µs.
The module operates using the versatile NI-DAQmx driver software, which is compatible with several development environments including LabVIEW, LabWindows/CVI, ANSI C, and .NET, making integration into existing systems seamless. Despite its high functionality, the NI-9244 maintains a low power consumption of 332 mW maximum when active, and a mere 50 µW when in sleep mode, highlighting its efficiency.
