Description
The USB-6281 is a PC-based Multifunction DAQ that includes a variety of features designed for a wide range of applications. With part numbers including 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04, this device is versatile and suitable for multiple configurations.
It offers 16 single-ended or 8 differential analog inputs, providing flexibility in connecting various types of sensors. The ADC resolution is 18-bits, ensuring high precision in measurements.
For sampling rates, the USB-6281 can achieve a maximum sample rate of 625 kS/s for a single channel, and up to 500 kS/s across multiple channels, allowing for rapid data acquisition. It is equipped with overvoltage protection of ±25 V when the device is on and ±15 V when the device is off, along with a maximum input current during overvoltage of ±25 mA per AI pin. The input bias current is remarkably low at ±100 pA, minimizing measurement errors.
Additionally, the USB-6281 provides two analog output channels with a DAC resolution of 16-bits. These outputs can be updated at a maximum rate of 2.86 MS/s for one output channel, and 2.00 MS/s per channel when both output channels are used simultaneously, ensuring swift responses in control applications.
