USB-2404-UI - 4-Channel, 24-Bit Universal Analogue Input Module

The USB-2404-UI provides four channels of 24-bit universal analogue input with integrated signal conditioning. 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 analogue 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.

"With reliability a key concern, we chose a name we could trust and the USB unit was a low-cost item that has proved very effective." Gordon Roxburgh, Volunteer Engineer, Brooklands Museum

"USB output has really made life easier on insutrumentation projects because you can simply swap from one laptop to another with minimal fuss. On this sort of operation that gives us extra confidence." Stephen Kemp, Manager, GBG Structural Services
