The voltage and thermocouple data acquisition module OM-USB-TC, OM-USB-TC-AI and OM-USB-5201 are USB 2.0
full-speed modules (fully
compatible with both USB 1.1 and USB 2.0 ports).
These are stand-alone plug-andplay modules which draw power
from the USB cable (included). No external power supply is required
(except for OM-USB-5201 which requires an ac adaptor). All
configurable options are software programmable, and the modules
are fully software calibrated.
The OM-USB-TC and OM-USB-5201 provide eight
differential thermocouple input channels and have two integrated
cold junction compensation (CJC) sensors for thermocouple
measurements. The OM-USB-TC-AI provides
eight analog input channels that are configured as four differential
temperature inputs and four differential or single-ended voltage
inputs. The module has one cold junction compensation (CJC)
sensors for the thermocouple measurements. Thermocouples
inputs are software programmable for types J, K, T, E, R, S, B
and N. An open thermocouple detection feature lets you detect a broken
thermocouple. An on-board microprocessor automatically
linearizes the thermocouple measurement data. Voltage inputs
(OM-USB-TC-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-5201 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-5201 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-5201). Data logging can only be done
when the OM-USB-5201 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).
The OM-USB-TC, OM-USB-TC-AI and OM-USB-5201 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 LibraryTM; ULx for NI
LabVIEW (comprehensive library of VIs and example programs
compatible with LabVIEW v.8.2.1 and later); and InstaCalTM
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.The OM-USB-TC, OM-USB-TC-AI
and OM-USB-5201 data 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:
• 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
TracerDAQ PRO is an enhanced version of TracerDAQ.
A comparison of some of the features included in TracerDAQ vs
TracerDAQ PRO is shown below.
