April 20, 2009 - Measurement Computing released a universal analog input module to the USB-2404 series of simultaneous data acquisition devices. The new module provides four channels of 24-bit universal analog input with integrated signal conditioning.The USB-2404-UI can be used to measure a variety of signal types, from such sensors 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 (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, 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 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.
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 2-meter USB cable and is powered by the +5 volt USB supply from your computer.
No external power is required.The USB-2404-UI series modules ship with an impressive array of software, including the new TracerDAQ®, a full-featured, out-of-the-box data logging, viewing, and analysis application; Universal Library™; and InstaCal™ installation, calibration, and test utility—powerful software solutions for programmers and nonprogrammers alike.The USB-2404-UI operates under Microsoft Windows 2000/XP/Vista® (32-bit) operating systems.
