The OM-USB-TEMP,
OM-USB-TEMP-AI and
OM-USB-5203 are USB 2.0 full
speed temperature input data
acquisition modules (fully compatible
with both USB 1.1 and USB 2.0 ports).
These are plug-and-play modules
which draw power from the USB
cable–no external power supply is
required (except for OM-USB-5203
which requires an ac adaptor). All
configurable options are software
programmable, and the modules
are fully software calibrated.
The OM-USB-TEMP and
OM-USB-5203 provide eight
differential temperature input
channels. The OM-USB-TEMP-AI
provides eight analog input channels
that are configured as four differential
temperature inputs and four
differential or single-ended
voltage inputs.
Temperature inputs are software
programmable for different sensor
types including type J, K, T, E, R,
S, B, N thermocouples, 2, 3 or
4-wire Pt100 RTDs, 2, 3 or 4-wire
thermistors and semi-conductor
sensors and are configured in
blocks of two channels. A different
type of sensor (thermocouple, RTD,
thermistor, semiconductor) can
be connected to each block of two
channels (both channels must be the
same type).
If the block of two channels is set up
for thermocouple inputs, it is possible
to mix thermocouple types. For
example, an OM-USB-TEMP can
be configured for 4 RTD inputs
and 4 thermocouple inputs but
not for 3 RTD inputs and
5 thermocouple inputs.
These modules have integrated
cold junction compensation
(CJC), linearization and open
circuit detection for thermocouple
measurements (OM-USB-TEMP
and OM-USB-5203 have two
integrated CJC sensors and the
OM-USB-TEMP-AI has one
CJC sensor. Voltage inputs
(OM-USB-TEMP-AI only) are
software programmable for ±10V,
±5V, ±2.5V and ±1.25V ranges.
Eight independent, TTL-compatible
digital I/O channels are provided
to monitor TTL-level inputs,
communicate with external devices
and to generate alarms. The
digital I/O channels are software
programmable for input or output.
The OM-USB-5203 features
eight independent temperature
alarms. Each alarm controls an
associated digital I/O channel as
an alarm output. The input to each
alarm is any one of the temperature
input channels.
The output of each alarm is software
configurable as active high or low.
The temperature threshold condition
to activate each alarm is user
programmable. When an alarm is
activated, the associated digital I/O
channel is driven to the output state.

The OM-USB-5203 also has data
logging capability. Measurements
can be logged to a standard
CompactFlash memory card (a 512
MB CompactFlash memory card is
included with the OM-USB-5203).
Data logging can only be done when
the
OM-USB-5203 is disconnected
from the computer. External power
is required for data logging via
the included ac adaptor. User
programmable settings in data
logging mode include sampling
interval and logging start mode (on
power up, on button press or at a
specified data
and time).
Software
The OM-USB-TEMP,
OM-USB-TEMP-AI and
OM-USB-5203 modules ship with
an impressive array of software,
including 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 VIs and example programs
compatible with 32-bit and 64bit LabVIEW 2010 or later) and
InstaCalTM installation, calibration
and test utility-powerful solutions for
programmers and nonprogrammers
alike. These modules operate under
Microsoft Windows® VISTA/7/8/10
(32-bit and 64-bit) operating systems.
The The OM-USB-TEMP,
OM-USB-TEMP-AI and
OM-USB-5203data acquisition
modules are 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:
•StripChart—Logandgraph
values acquire from analog inputs,
digital inputs, temperature inputs
and counter inputs
•Oscilloscope—Displayvalues
acquired from analog inputs
•FunctionGenerator—Generate
waveforms for analog outputs
•RateGenerator—Generate
waveforms for counter outputs
