Description
The USB-6281 is a sophisticated PC-based Multifunction DAQ product manufactured by National Instruments. This device is designed for precision measurement, featuring 16 single-ended or 8 differential analog input channels with an 18-bit ADC resolution. It is capable of a maximum sample rate of 625 kS/s for a single channel and 500 kS/s across multiple channels, ensuring high-speed data acquisition for a wide range of applications.
For durability and reliability, it offers overvoltage protection of ±25 V when on and ±15 V when off, safeguarding the device against unexpected voltage spikes. Furthermore, it can handle a maximum input current of ±25 mA per AI pin during overvoltage conditions. The input bias current is impressively low at ±100 pA, minimizing measurement errors due to leakage currents.
The USB-6281 also boasts 2 analog output channels with a 16-bit DAC resolution, capable of a maximum update rate of 2.86 MS/s for one channel, providing precise control signals for your experiments or control systems. The versatility of this device, combined with its robust protection features, makes it an excellent choice for researchers, engineers, and professionals looking for reliable data acquisition and control solutions.
Its part numbers include 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04, accommodating a range of configurations to meet various application requirements.
