USB Data Acquisition | USB-2404-UI

The device can be used to measure a variety of sensor types such as RTDs, thermocouples, load cells, and other powered sensors. The four channels are individually configurable, so a different measurement type can be performed on each channel. All channels are measured simultaneously at up to 100 S/s per channel.

The USB-2404-UI can perform the following measurements:

• Voltage
• Current
• Thermocouple
• RTD (4-wire and 3-wire)
• Resistance (4-wire and 2-wire)
• Bridge-based sensors (quarter-, half-, and full-bridge)

Measurement ranges vary for each type of measurement.

The device features built-in current and voltage excitation. The excitation circuit is protected from overcurrent and overvoltage fault conditions. Each channel also has a built-in thermistor for cold-junction compensation (CJC) calculations when measuring thermocouples. An analog prefilter removes noise that may be present in the signals prior to conversion.

With 250 VAC channel-to-channel and channel-to-ground isolation, the USB-2404-UI protects the individual channels and connected computer and ensures a reliable data stream. Each channel has a detachable six-position spring terminal for field wiring connections. The USB-2404-UI ships with a 2m USB cable and is powered by the +5 volt USB supply from your computer. No external power is required. The USB-2404-UI is a USB 2.0 high-speed device that is supported under popular Microsoft Windows® operating systems. The USB-2404-UI is fully compatible with both USB 1.1 and USB 2.0 ports.
