Description
The product with the part number 197596A-03L, which also goes by alternate part numbers including 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04, is a multifunctional DAQ device known as the USB-6281. This device falls under the category of PC-based Multifunction DAQ and is specifically the NI USB-6281 M Series OEM model. Manufactured by National Instruments, it is designed to meet various data acquisition needs.
Regarding its specifications, the USB-6281 features 16 single-ended or 8 differential analog input channels, providing flexibility in connecting different types of sensors. The analog-to-digital conversion (ADC) resolution is 18-bits, ensuring high precision in measurements. For sampling rates, it offers a 625 kS/s maximum rate for single-channel sampling and a 500 kS/s maximum rate for multiple-channel sampling, enabling efficient data collection across multiple channels simultaneously.
The device is designed with robust overvoltage protection of ±25 V when the device is on and ±15 V when the device is off, safeguarding the equipment against unexpected voltage spikes. During overvoltage conditions, the input current is limited to ±25 mA maximum per AI pin, and the input bias current is maintained at ±100 pA, ensuring the device’s integrity and operational safety.
In addition to its analog input capabilities, the USB-6281 also boasts 2 analog output channels with a 16-bits DAC resolution. This allows for precise control signals to be sent from the device, suitable for a wide range of applications. The output channel update rate further complements its performance, although the specific rate is not mentioned in the provided details.
Overall, the USB-6281 from National Instruments is a versatile, high-performance PC-based multifunction DAQ device designed for precise and efficient data acquisition and control.
