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.
