Analogue input module added to USB-2404 DAQs

An Adept Scientific product story
Edited by the Engineeringtalk editorial team May 8, 2009

Adept Scientific has announced the release of Measurement Computing's universal analogue input module to the USB-2404 series of simultaneous data acquisition devices.

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

Whereas the USB-2404-10 and USB-2404-60 modules measured voltage only (+/- 10V and +/- 60V, respectively), the USB-2404-UI can be used to measure a variety of signal types, from sensors such as RTDs, thermocouples, load cells and other powered sensors.

Each of the four channels has a detachable six-position spring terminal, which is 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 (four-wire and three-wire); resistance (four-wire and two-wire); and 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, which is protected from both overcurrent and overvoltage fault conditions.

Each channel also has a built-in thermistor for cold-junction compensation (CJC) calculations when measuring thermocouples.

An analogue pre-filter removes noise that may be present in the signals prior to conversion.

With 250VAC 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.

The status of the device is indicated by an on-board LED.

Each channel has a detachable six-position spring terminal for field wiring connections.

Additional connectors are available for purchase.

A strain relief kit is also available to secure signal wires.

The USB-2404-UI ships with a 2m USB cable and is powered by the +5V USB supply from a computer - no external power is required.

The USB-2404-UI series modules ship with an array of software, including TracerDAQ, a full-featured, out-of-the-box data logging, viewing and analysis application; Universal Library and Instacal installation, calibration and test utility.

The USB-2404-UI operates under Microsoft Windows 2000/XP/Vista (32-bit) operating systems.
