The OM-WLS-TC is a wireless USB
2.0 full-speed thermocouple input
module (fully compatible with both
USB 1.1 and 2.0). The OM-WLS-TC
provides 8 differential thermocouple
input channels. 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-WLS-TC supports
Types J, K, T, E, N, R, S and B
thermocouples. Two integrated
cold junction compensation
(CJC) sensors are included for
thermocouple measurements.
An open thermocouple detection
feature allows detection of a
broken thermocouple. An onboard
microprocessor automatically
linearizes the measurement data.
The OM-WLS-TC features 8
independent temperature alarms.
Each alarm controls an associated
digital I/O channel as an alarm
output. The input to each alarm is
one of the temperature channels.
The output of each alarm is
software configurable as active high
or low. The temperature threshold
conditions to activate each alarm
are software programmable. When
an alarm is activated, the associated
digital output channel is driven to
the output state. All configurable
options are software programmable.
OM-WLS-TC,
shown smaller
than actual size.
The OM-WLS-TC
is fully software-calibrated.
The OM-WLS-TC can be operated
as a standalone plug-and-play
device which draws power through
the USB cable. The unit can also be
operated as a remote device that
communicates with the computer
through the OM-WLS-IFC USBto-wireless interface device. An
external power supply is shipped
with the device to provide power
during remote operation.
When operating as a remote device,
the OM-WLS-TC communicates
with the computer through the
OM-WLS-IFC device connected to
the computer’s USB port. Before
the OM-WLS-TC can be operated
remotely, it needs to be connected
to the computer’s USB port and the
network parameters configured to
establish a wireless link with the
interface device.
Only devices with the same
parameter settings can
communicate with each other. All
configurable options are software
programmable using the included
InstaCal™ utility software.
LEDs on the OM-WLS-TC indicate
the status of communications over
the wireless link. A LED bar graph
shows the fade margin of signals
received by the OM-WLS-TC.
Software
The OM-WLS-TC 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
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 2012) and
InstaCalTM installation, calibration
and test utility-powerful solutions for
programmers and nonprogrammers
alike. These modules operate under
Micrsoft Windows® XP (32-bit only)
and VISTA/7/8 (32-bit and 64-bit)
operating systems.
