Description
The USB-6251 OEM Board-Only Kit is a PC-based multifunction Data Acquisition (DAQ) device, part number 194929-03, manufactured by National Instruments. This model, USB-6251, is designed for versatile applications without an enclosure, making it ideal for embedded solutions.
It features 8 differential or 16 single-ended analog input channels, providing flexibility in connecting a variety of sensors. The maximum sampling rate for a single channel reaches up to 1.25 MS/s, while for multiple channels, it can achieve up to 1.00 MS/s, ensuring accurate and rapid data acquisition for both simple and complex measurement needs.
The USB-6251 supports a wide range of input ranges, including ±1 V, ±2 V, ±5 V, ±10 V, ±0.1 V, ±0.2 V, and ±0.5 V, allowing it to accommodate various signal types. With an input impedance of 10 GΩ, it ensures minimal loading on the measured signal, preserving signal integrity.
To maintain accuracy, a 30-minute warm-up time is required, and calibration is recommended at least once every two years. This ensures long-term reliability and precision of measurements.
In terms of output capabilities, the USB-6251 provides 2 analog output channels, with an update rate of 2.86 MS/s for a single channel and 2.00 MS/s for two channels. This allows for precise control signals or stimulus generation for testing and simulation applications.
