National Instruments USB-6451

The National Instruments USB-6451 (part number 789888-01) is a multifunction USB Type-C bus-powered mioDAQ device designed for a range of analog and digital input/output applications. Optimized for performance, this compact device features 16 analog input channels that can be configured for either single-ended or differential modes, enabling simultaneous sampling rates of up to 1 MS/s across eight channels. The analog inputs support multiple ranges from ±0.2 V to ±10 V, ensuring measurement versatility and precision.

For output capabilities, the USB-6451 is equipped with two 16-bit analog output channels, each with a range of ±10 V and a maximum update rate of 250 kS/s, making it suitable for various signal generation tasks. The device also includes 16 configurable digital I/O lines that support static I/O, waveform outputs, and trigger control, with clock frequencies reaching up to 10 MHz, allowing for individualized line programming to accommodate diverse testing and automation requirements.

Additionally, the USB-6451 features four general-purpose 32-bit counters useful for applications such as pulse and frequency measurement and position encoding. Connectivity is enhanced through two 36-position spring terminals for I/O connections, and the device is designed to operate within a robust temperature range from 0 °C to 55 °C, with storage capabilities extending down to -20 °C. The USB-6451 fulfills stringent environmental specifications, supporting operation at humidity levels of up to 90% (non-condensing) and altitudes of up to 2000 m.

Further facilitating ease of use, the device is bundled with NI’s FlexLogger Lite software, which offers free tools for data acquisition, and provides extensive programming support across various environments, including LabVIEW, Python, and C/C++. This powerful USB device is tailored for engineers and researchers who require a compact and efficient data acquisition solution for both laboratory and field applications.
