The new OM-USB-2404 Series are high-speed
USB data acquisition modules featuring four 24-bit
simultaneous analog voltage inputs with a sampling
rate of 50 kS/s per channel, and a ±10V
(OM-USB-2404-10) or ±60V (OM-USB-2404-60)
input range. These modules are fully compatible with
both USB 1.1 and USB 2.0 ports. An anti-alias filter
removes noise that may be present in the signals prior
to conversion.
Full 250 Vrms channel-to-channel and channel-to-ground
isolation protects the module and computer
from ground spikes, and ensures a reliable data stream.
An on-board LED indicates the status of the device.
Field connections are made to four 2-pole, detachable
screw terminals. The USB 2.0 high-speed driver
transfers data at rates up to 480 Mbps.
Power for the OM-USB-2404 Series comes from the
5V USB supply from your computer. No external power
is required.
Software
The OM-USB-2404 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. 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.
