Description
The NI-9238 is a part of the C Series Analog Input category, bearing the part number 783311-01. This module is designed to provide a high-level precision with its 4-Channel Voltage Input capability, making it suitable for a wide range of applications. Each channel is capable of differential analog inputs, ensuring accurate and noise-free measurements.
The NI-9238’s measurement range is ±500 mV, allowing for the monitoring of low-voltage signals with high precision. It also boasts a 250 Vrms continuous isolation between channels, enhancing its safety and reliability in complex electrical environments. To further protect against unexpected power surges, the module is equipped with surge protection of up to 1,500 Vrms.
With a sampling rate of 50 kS/s per channel, the NI-9238 can capture rapid changes in the signal, making it an ideal choice for dynamic applications. The module’s 24-bit resolution ensures that even the smallest changes in the signal are accurately represented, providing users with detailed and precise data.
The input coupling type is DC, which is suitable for a wide range of signal types. For connectivity, the module uses a screw-terminal mechanism, facilitating easy and secure connections. Its input impedance is greater than 1 GΩ, minimizing the load on the measured signal and preserving signal integrity.
In terms of noise, the NI-9238 has an input noise level of 3.9 μVrms, which is remarkably low, ensuring that measurements are not compromised by external or internal noise sources. The module also exhibits a gain error of ±0.20% and an offset error of ±0.06%, indicating high accuracy and stability in measurements.
Supported by NI-DAQmx driver software, the module provides a seamless and user-friendly interface for configuring and collecting data, making it accessible for users of all experience levels. Weighing 5.15 oz, the NI-923
