Description
The National Instruments USB-6281 is a PC-based multifunction DAQ device, designed to meet a wide range of data acquisition needs. The device is noted for its part numbers which include 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04, indicating various configurations or versions that cater to different requirements.
At the heart of its specifications, the USB-6281 boasts 16 single-ended or 8 differential analog input channels, providing flexibility in connecting various types of sensors. The precision of data acquisition is ensured by an 18-bits ADC resolution, allowing for detailed and accurate readings. When operating on a single channel, the device can achieve a maximum sample rate of 625 kS/s, which slightly reduces to 500 kS/s when multiple channels are being utilized simultaneously.
Regarding durability and protection, the USB-6281 is equipped with robust overvoltage protection, ensuring device safety when powered on (±25 V) and off (±15 V). In addition, it can handle a maximum input current (overvoltage) of ±25 mA/AI pin, with an input bias current of ±100 pA, safeguarding the device and connected components from potential damage due to unexpected electrical surges.
Furthermore, the device features 2 analog output channels, with a 16-bits DAC resolution. This supports sophisticated signal generation capabilities, with a maximum update rate of one channel reaching up to 2.86 MS/s, enabling the output of complex waveforms at high speeds.
In summary, the National Instruments USB-6281 stands out as a high-performance, versatile DAQ device, ideal for a wide range of data acquisition and signal generation tasks in various industrial, research, and academic applications.
