The USB-6251 is a PC-based Multifunction DAQ part of the M Series, specifically designed for a wide range of applications. It carries the part number 779694-09 and is provided by National Instruments. This model is equipped for both Korean and international markets, featuring DAQmx and SignalExpress LE software for efficient data acquisition and analysis.
This DAQ system supports various connector variations, including Screw Terminal, BNC, and Mass Terminal, making it versatile for different connection needs. It provides up to 8 differential or 16 single-ended analog input channels, with a sampling rate of 1.25 MS/s for a single channel and 1.00 MS/s for multiple channels. The input range is quite flexible, allowing for ±1 V, ±2 V, ±5 V, ±10 V, ±0.1 V, ±0.2 V, ±0.5 V configurations, with a working voltage of ±11 V (signal and common mode).
The USB-6251 boasts an input impedance of 10 GΩ (on/off) and requires a 30-minute warm-up time for optimal performance. It is recommended that the device undergoes calibration at least once in 2 years to maintain accuracy.
In terms of output capabilities, this model includes 2 analog output channels, with an update rate of 2.86 MS/s for 1 channel and 2.00 MS/s per channel for 2 channels. The timing resolution is precise at 50 ns, and the output range can be adjusted to ±5 V or ±10 V depending on the requirements of the application.
