Description
The USB-6281 M Series DAQ is a product of National Instruments, known for its high-quality data acquisition systems. This particular model comes with various part numbers including 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04, offering a range of options for specific needs.
It features 16 single-ended or 8 differential analog input channels, providing flexibility in connecting sensors or other input devices. The Analog-Digital Converter (ADC) resolution is 18 bits, ensuring high precision in the conversion process. When operating a single channel, the maximum sample rate is 625 kS/s, while for multiple channels, it is slightly lower at 500 kS/s max, accommodating the increased data throughput.
In terms of durability and protection, this device offers overvoltage protection of ±25 V when powered on and ±15 V when off. The input current during overvoltage conditions is limited to ±25 mA max per AI pin, complemented by an input bias current of ±100 pA, demonstrating the device’s capability to handle unexpected electrical events.
On the output side, the USB-6281 M Series DAQ is equipped with 2 analog output channels, each with a 16-bit DAC resolution. The single output channel update rate can reach up to 2.86 MS/s max, and when both channels are used, the update rate is a maximum of 2.00 MS/s per channel. This high-speed data output allows for real-time control and feedback applications. Furthermore, the timing accuracy of 50 ppm ensures that the timing of data acquisition and output operations is maintained with high precision across various environmental conditions.
