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,
OM-USB-TEMP-AI and
OM-USB-5203
OM-USB-TEMP-AI has one CJC
sensor. Voltage inputs (OM-USBTEMP-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

power up, on button press or at a

The OM-USB-TEMP,
OM-USB-TEMP-AI and
OM-USB-5203 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™;
ULx for NI LabVIEW
(comprehensive library of VIs and
example programs compatible with
LabVIEW v.8.2.1 and later); and
InstaCal™ installation, calibration,
and test utility—powerful software
solutions for programmers and
nonprogrammers alike. These
modules operate under Microsoft
Windows 2000/XP/VISTA (32-bit
or 64-bit) /7 (32-bit or 64-bit)
operating systems.

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:
• Strip Chart—log and graph values
acquire 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
