Description
“`html
The NI USB-6251 M Series DAQ Device, with part number 780115-11, falls under the category of PC-based Multifunction DAQ. This device is designed to offer a versatile solution for data acquisition, featuring a range of connector variations including screw terminal, BNC, and Mass terminal to accommodate various application needs.
With a maximum sampling rate of 1.25 MS/s for single channel operations and 1.00 MS/s for multiple channels, it provides reliable performance for both individual and simultaneous measurements. The device supports 8 differential or 16 single-ended analog input channels, offering flexibility in handling various types of signals.
The input range of the device is quite extensive, supporting ±1 V, ±2 V, ±5 V, ±10 V, ±0.1 V, ±0.2 V, and ±0.5 V, making it suitable for a wide range of measurement tasks. The high input impedance of 10 GΩ ensures minimal loading on the circuit being measured.
Before reaching optimal performance, the device requires a warm-up time of 30 minutes. For maintaining accuracy and reliability, it is recommended that the device undergoes calibration at least once every two years.
In addition to its input capabilities, the device also features 2 analog output channels with an output range of ±5 V and ±10 V. This allows for the generation of precise voltage signals for testing or control purposes.
