MCC USB-2404-UI Universal Input USB DAQ Device

Digilent's measurement computing USB-2404-UI features four simultaneous analog inputs capable of measuring voltage, current, thermocouples, RTDs, resistance, and bridge-based sensors. This device features an A/D per channel and includes channel-to-channel and system-to-host isolation. This device is USB-powered and requires no external power. The USB-2404-UI provides four individually configurable channels of 24-bit universal analog input with integrated signal conditioning. All channels are measured simultaneously at up to 100 S/s per channel. The USB-2404-UI can perform voltage (±60 V, ±15 V, ±4 V, ±1 V, ±125 mV), current, thermocouple, RTD (4-wire and 3-wire), resistance (4-wire and 2-wire), and bridge-based sensor (quarter-, half-, and full-bridge) measurements. Measurement ranges vary for each type of measurement. The USB-2404-UI features built-in current and voltage excitation. The excitation circuit is protected from overcurrent and overvoltage fault conditions. The USB-2404-UI supports class II TEDS smart sensors and includes a built-in thermistor for cold-junction compensation (CJC). An analog pre-filter removes noise that may be present in the signals before conversion.

High-speed, 60 Hz rejection, 50 Hz rejection, and high-resolution timing options are supported. Each option is optimized for different types of applications by using different ADC conversion times. High-speed is optimized for high-speed applications at the expense of noise rejection, 60 Hz rejection is optimized for rejection of 60 Hz noise, 50 Hz rejection is optimized for rejection of 50 Hz noise, and high-resolution is optimized for maximum overall noise rejection and provides good rejection of both 50 Hz and 60 Hz noise. Each channel has a 6-position detachable spring connector for field wiring connections.

Software support includes TracerDAQ, an out-of-the-box application for data logging, visualization, and signal generation. Data can be viewed in real-time or post-acquisition on user-configurable displays. Drivers are included for the most popular applications and programming languages including Visual C++®, Visual C#®, Visual Basic® .NET, DASYLab®, LabVIEW™, and Python™.
