National Instruments USB-6451 Is a Multifunction USB Type-C Bus-Powered mioDAQ Device

The National Instruments USB-6451 (part number 789888-01) is a multifunction USB Type-C bus-powered mioDAQ device, optimized for both analog and digital input/output operations. This versatile device includes 16 analog input channels (AI) configurable for single-ended or differential mode, allowing simultaneous sampling up to 1 MS/s across eight channels. The analog input channels offer multiple input ranges, from ±0.2 V to ±10 V, providing flexibility in measurement precision.

For output, the USB-6451 has two 16-bit analog output channels (AO) with a range of ±10 V and a maximum update rate of 250 kS/s, ideal for precise signal generation tasks. The digital I/O features 16 configurable lines with functions including static I/O, waveform I/O, and trigger control, supporting clock frequencies up to 10 MHz. Each line can be programmed individually, making it adaptable for various test and automation setups. The USB-6451 includes four general-purpose 32-bit counters, enabling applications in pulse and frequency measurement, as well as position encoding.

Designed with robust connectivity options, the USB-6451 incorporates two 36-position spring terminals for I/O connections. Its durable build supports operating temperatures from 0 °C to 55 °C, withstanding storage down to -20 °C. This device meets rigorous environmental specifications, allowing operation in up to 90% relative humidity (noncondensing) and at altitudes up to 2000 m.

The USB-6451 is further complemented by NI’s FlexLogger Lite software, which provides free data acquisition tools, and extensive support for programming environments like LabVIEW, Python, and C/C++. This powerful USB device is tailored to meet the needs of engineers and researchers seeking a compact, efficient data acquisition solution for laboratory and field applications.
