National Instruments NI-9201

The National Instruments NI-9201 is a C Series Voltage Input Module that offers an exceptional balance of speed and channel density. This module features eight single-ended analog input channels, supporting a voltage range of ±10 V with a 12-bit resolution. The NI-9201 is capable of a maximum sampling rate of 500 kS/s, making it suitable for high-speed data acquisition tasks. Each channel is equipped with integrated overvoltage protection, rated up to ±100 V, ensuring reliability even in scenarios with potential erratic signal connections. The module operates with minimal gain and offset errors of ±0.04% and ±0.07%, respectively, and demonstrates impressive thermal stability with gain drift of ±34 ppm/°C and offset drift of ±100 μV/°C.

The NI-9201 consumes 1 W in active mode and only 1 mW in sleep mode, contributing to energy efficiency. For connectivity, the module is offered in multiple configurations, including screw terminal, spring terminal, and D-Sub connector options. It is designed for use in Measurement Category II applications, capable of handling constant voltages up to 250 Vrms, and has been tested for surge withstand up to 2,300 Vrms. With a mean time between failures (MTBF) of 1,092,512 hours, the NI-9201 is built for long-term reliability. Compatible with the NI-DAQmx driver software, it integrates seamlessly with various application development environments such as LabVIEW, LabWindows/CVI, C/C++, C#, and Visual Basic .NET. Additionally, it demonstrates a recommended operating temperature range of -40 °C to 70 °C, making it versatile for various industrial applications.

Part numbers for the NI-9201 include 779372-01 (D-Sub), 783730-01 (spring terminal), 779013-01 (screw terminal), and 189880-51 (OEM version), with a three-year warranty provided. Documentation, including the user manual, is available for download. For pricing, please contact a sales representative.
