Description
The multifunction I/O device, known as the USB-6281, is a product of National Instruments. This device comes with a variety of part numbers, including 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04. It is designed to offer users a comprehensive solution with its 16 single-ended or 8 differential analog input channels and an 18-bits ADC resolution.
The USB-6281 is capable of achieving a maximum sample rate of 625 kS/s for a single channel and 500 kS/s for multiple channels. This ensures high-speed data acquisition for a variety of applications. The device also features robust overvoltage protection, providing ±25 V protection when the device is on and ±15 V when it is off. Furthermore, it can handle a maximum input current per AI pin during overvoltage conditions of ±25 mA and maintains an input bias current of ±100 pA.
In addition to its analog input capabilities, the USB-6281 boasts 2 analog output channels with a 16-bits DAC resolution. It supports a maximum update rate of 2.86 MS/s for one channel, allowing for precise control signals to be generated. This makes the USB-6281 an ideal choice for a wide range of measurement and control applications, providing both versatility and reliability in a single device.
