Description
The PC-based Multifunction DAQ, model USB-6251, is identified by its part number 779627-10. This device utilizes a Screw Terminal connector type for establishing connections. It is designed to work with DAQmx and SignalExpress LE (Chinese) software, providing a versatile platform for data acquisition tasks.
It features 8 differential or 16 single-ended analog input channels, capable of a maximum sampling rate of 1.25 MS/s for a single channel and 1.00 MS/s for multi-channel operations. The input range of the device is quite flexible, offering options such as ±1 V, ±2 V, ±5 V, ±10 V, ±0.1 V, ±0.2 V, and ±0.5 V. Moreover, it can handle a working voltage of ±11 V (signal and common mode) and boasts an input impedance of 10 GΩ, whether powered on or off.
For optimal performance, the device requires a 30-minute warm-up time and should undergo calibration at least every 2 years. In terms of output capabilities, the USB-6251 provides 2 analog output channels, with an update rate of 2.86 MS/s for a single channel and 2.00 MS/s for two channels. The timing resolution of the device is 50 ns, and it offers an output range of ±5 V and ±10 V, with an output current drive of ±5 mA.
The physical dimensions of the USB-6251 vary based on the connector type. For the Screw Terminal version, the dimensions are 10.5 x 6.73 x 1.75 inches. Meanwhile, the BNC version measures 11.25 x 6.7 x 2.7 inches.
