Description
The NI-9238 is a model from the C Series Analog Input category, designed to provide high precision and versatility for various measurement applications. It comes with part numbers 198914B-11L and 783311-01, ensuring you can identify the specific model you need for your setup.
This module boasts a 24-Bit resolution, offering high-quality data acquisition capabilities. It is equipped with 4-channel voltage input, which are differential, enhancing its ability to measure signals accurately even in electrically noisy environments. The measurement range of the NI-9238 is ±500 mV, allowing for the capture of small signal variations with high fidelity.
One of the key features of the NI-9238 is its robust isolation capabilities. It offers 250 Vrms continuous channel-to-channel isolation, and can withstand 1,500 Vrms surge voltage, ensuring the safety and integrity of measurements even under extreme conditions. The module’s sampling rate is 50 kS/s per channel, providing ample speed for capturing fast-changing signals.
The device operates on a 12.8 MHz time base, which aids in maintaining precise timing for sampled data. With an input impedance of >1 GΩ, it minimizes loading on the signal being measured, preserving the original signal quality. The input noise level is remarkably low at 3.9 µ Vrms, which is crucial for applications requiring the detection of very small signals.
Accuracy is further enhanced with a gain error of ±0.20% and an offset error of ±0.06%, ensuring reliable measurements. The input coupling is DC, making it suitable for a wide range of measurement tasks. For easy and secure connections, the NI-9238 utilizes a screw-terminal connectivity method.
