Description
The National Instruments USB-6281 is a PC-based Multifunction DAQ designed for a wide range of applications. It is part of an extensive line of DAQ products manufactured by National Instruments, a leader in the field. This model, specifically, is versatile and suitable for various data acquisition tasks.
The USB-6281 supports 16 single-ended or 8 differential analog input channels, offering flexibility in connecting different types of sensors. With an ADC resolution of 18-bits, it ensures high precision in measurements. The device can achieve a maximum sample rate of 625 kS/s for a single channel, which decreases slightly to 500 kS/s when multiple channels are used simultaneously, allowing for efficient data collection from multiple sources.
One of the key features of the USB-6281 is its robust overvoltage protection. When the device is on, it can withstand up to ±25 V, and when off, up to ±15 V, protecting the device from unexpected voltage spikes. Additionally, the maximum input current during overvoltage conditions is rated at ±25 mA per AI pin, with an input bias current of ±100 pA, ensuring the device’s safety and longevity.
Besides its impressive input capabilities, the USB-6281 also offers 2 analog output channels with a DAC resolution of 16-bits. This allows for precise control signals to be generated, with a maximum update rate of 2.86 MS/s for one output channel, facilitating high-speed operations.
With part numbers including 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04, the USB-6281 is a highly versatile and reliable choice for professionals seeking a top-tier multifunction DAQ device.
