The OM-USB-TC, OM-USB-TC-AI
and OM-USB-5201 are USB 2.0
full-speed thermocouple input
data acquisition 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, TTLcompatible 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.
OM-USB-TC,
OM-USB-TC-AI
and OM-USB-5201
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).
