Description

This product has been discontinued.

The new OM-USB-2404-UI provides four channels of 24-bit universal analog 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 OM-USB-2404-UI can perform the following measurements: • Voltage • Current • Thermocouple • RTD (3- and 4-wire) • Resistance (2- and 4-wire) • Bridge-based sensors (quarter-, half-, and full-bridge) Measurement ranges vary for each type of measurement (see PDF for complete specifications).

The device features a 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 pre-filter removes noise that may be present in the signals prior to conversion.

With 250 Vac channel-to-channel and channel-to-ground isolation, the OM-USB-2404-UI protects the individual channels and connected computer and ensures a reliable data stream. Each channel has a detachable six-position screw terminal block for field wiring connections.

The OM-USB-2404-UI ships with a 2 m (6') USB cable and is powered by the 5V USB supply from your computer. No external power is required.

The OM-USB-2404-UI is a USB 2.0 high-speed device that is supported under popular Microsoft Windows® operating systems. The OM-USB-2404-UI is fully compatible with both USB 1.1 and USB 2.0 ports.

Software The OM-USB-2404-UI module ships with an impressive array of software, including the new TracerDAQ®, a full-featured, out-of-the-box data logging, viewing, and analysis application. Driver support and detailed example programs are included for Universal Library programming libraries for Microsoft® Visual Studio® programming languages, and other languages, including DASYLab®, and ULx for NI LabVIEW® (comprehensive library of Vls and example programs compatible with 32-bit and 64-bit LabVIEW v8.5 through 2013) and InstaCal™ installation, calibration and test utility-powerful solutions for programmers and nonprogrammers alike. These modules operate under Microsoft Windows® XP (32-bit only) and VISTA/7/8 (32-bit and 64-bit) operating systems.

The OM-USB-2404-UI data acquisition module is supplied with TracerDAQ software which is a collection of four virtual instrument applications used to graphically display and store input data and generate output signals:
    • Strip Chart—Log and graph values acquired from analog inputs, digital inputs, temperature inputs and counter inputs
    • Oscilloscope—Display values acquired from analog inputs
    • Function Generator—Generate waveforms for analog outputs
    • Rate Generator—Generate waveforms for counter outputs
TracerDAQ PRO is an enhanced version of TracerDAQ. A comparison of some of the features included in TracerDAQ vs TracerDAQ PRO is shown on the PDF.
