Description
The NI-9244 is a robust C Series Analog Input module designed for precision voltage measurement. The module carries a part number of 155386A-02L, with an alternative part number of 783106-01 for flexibility in sourcing. It is classified as a Voltage Input Module, specifically engineered to cater to demanding applications that require high accuracy and reliability.
At the core of the NI-9244’s capabilities is its 24-bit Delta-Sigma ADC (Analog-to-Digital Converter) per channel, ensuring high-fidelity data conversion with minimal noise interference. This module supports 3 single-ended, simultaneously sampled Analog Input (AI) channels, which allows for synchronous data acquisition at speeds up to 50 kS/s (kilo-samples per second) per channel. Such a feature is crucial for applications requiring simultaneous data collection from multiple sources without time delay or phase shift.
The NI-9244 is designed to handle a wide input range of up to 800 Vrms L-L (line-to-line), making it suitable for high-voltage applications. Its connectivity is facilitated through a screw-terminal interface, ensuring secure and reliable connections. The module boasts a maximum input noise of 6 mVrms, maintaining signal integrity even in noisy environments.
With DC input coupling and a high input impedance of 2 MΩ, the NI-9244 is capable of interfacing with a variety of signal sources, enhancing its versatility. It also offers robust overvoltage protection up to 800 Vrms continuous, with the ability to withstand up to 1000 Vrms for 1 second, safeguarding the module against unexpected voltage spikes. Additionally, the module is equipped with surge protection rated at 8 kV for 1.2 µs/50 µs, further enhancing its resilience against transient voltage surges.
