Analog Inputs
The LabJack U12 has 8 screw terminals for analog input signals (AI0-AI7). These can be
configured individually as 8 single-ended channels, 4 differential channels, or
combinations in between. Each input has a ±10 volt input range, 12-bit resolution, and an
input bias current of ±90 microamps. Differential channels can make use of the low noise
precision PGA to provide gains up to 20, giving an effective resolution greater than
16-bits. The analog inputs are calibrated at the factory, and the calibration constants
are stored in the LabJack's nonvolatile memory where they can be easily updated at any
time.
The LabJack U12 is capable of both
software and hardware timed acquisition. When using software timed acquisition (also
called command/response), the PC sends a command to the LabJack, and it responds with
data. This mode can acquire 4 channels at up to 50 samples/second per channel, or 8
channels at up to 25 samples/second per channel. When using hardware timed acquisition,
the PC sends a command to the LabJack telling it to start a burst or stream mode
acquisition. Both burst and stream mode take advantage of the LabJack's precision timing
crystal and high-speed sample buffer. In burst mode, up to 4,096 samples will be acquired
from 1-4 channels at up to 8,192 samples/second and stored in the buffer. After the
acquisition is complete, the data is transferred to the PC. A hardware trigger can be
configured for burst mode that starts the acquisition when a digital input changes state.
In stream mode, data is acquired from 1-4 channels at up to 1,200 samples/second and
stored in the LabJack buffer. Simultaneously, the data is transferred from the LabJack
buffer to the PC buffer, allowing the data to be streamed to disk continuously. More Info on Data Rates
Using
Thermocouples, RTD, mV sources or Potentiometers with Labjack
We sell a range of
programmable transmitters
which will convert the output of any thermcouple, RTD, mV source or potentiometer to a
4-20mA signal or 0-10V signal.
Analog Outputs
The LabJack U12 has 2 screw
terminals for analog output signals (AO0 & AO1). Each analog output can be set to a
voltage between 0 and the supply voltage (+5 volts nominal) with 10-bits of resolution.
The analog outputs are controlled in command/response mode at up to 50 Hz per channel.
Digital I/O
The LabJack U12 has 20 digital I/O
channels which can be individually configured as input or output.
Connections to 4 of the digital I/O
are made with the built-in screw terminals (IO0-IO3). These 4 channels have built-in
overvoltage/short-circuit protection. As inputs or outputs, they are controlled/read in
command/response mode at up to 50 Hz per bit. As inputs only, they can be read with the
high-speed burst and stream modes.
The remaining 16 digital I/O are
accessed through the DB-25 connector and controlled/read in command/response mode at up to
50 Hz per bit. These channels can sink or source up to 25 mA each (total sink or source
current of 200 mA max for all 16), allowing direct interface to many
relays.
Counter
There is one 32-bit counter
available on the LabJack U12 (screw terminal CNT), capable of counting frequencies up to 1
MHz. The counter is read in command/response mode at up to 50 Hz.
Watchdog Timer Function for
Unattended Operation
The LabJack U12 also has a watchdog
timer function available which can change the states of digital I/O if the LabJack does
not successfully communicate with the PC within a specified timeout period. This function
could be used to reboot the PC allowing for reliable unattended operation.
Portable Data Acquisition
and Control
When used with a notebook PC, the
LabJack U12 becomes a convenient portable data acquisition and control system. The
watchdog timer function allows the development of a system which has the reliability of a
datalogger with the power of a PC. The low-power design of the LabJack U12 allows it to
draw all it's power from the USB port. Also, no UPS is needed when using a LabJack U12
with a notebook PC. In the event of power loss, both the LabJack and the notebook will
continue to operate.
High Channel Count
Applications
By using USB hubs, up to 80 LabJacks
can be connected to a single USB port, providing an inexpensive solution for low-speed
high channel count applications.
ISEE-LABJACK Data
Acquistion Program
The ISEE-LABJACK data
acquisition program is a minimum cost (A$45 approximately US$25) HMI program for the
Labjack making it one of the most powerful data acquisition and control devices for its
price on the market today. Running under Windows XP/2000/NT/ME/98 it allows the user to
- View the analog inputs. They can be viewed as raw readings or in
engineering units.
- View the status of the digital inputs
- Control the status of the digital outputs
- Write to the Analog Outputs
- Display the analog inputs on graphs or trends
- View the maximum and minimum values for each of the analog inputs
- Log analog inputs and digital inputs and calculated variables to disk
- Display and control alarms
- Has a control language consisting of 50 If-Then statements allowing
calculations and
control to be done
- The program configuration can be saved to disk

ISEE-LABJACK Program
To PURCHASE the ISEE-Labjack Program
for A$45
Free Application Software
Includes Daqfactory Express and example applications LJlogger and
LJscope. Daqfactory Express is a HMI program that allows you to display
and graph the inputs, log data and much more. LJlogger provides datalogger type
functionality. It reads all inputs, controls all outputs, writes real time data to the
Internet or hard disk, and sends email when events are triggered. LJscope is a virtual
oscilloscope program.
Free Driver Software
Drivers are provided as a DLL which can
be called from most programming languages (Visual Basic, Visual C++, Borland Delphi and
C++ etc. Also included are an ActiveX wrapper and LabVIEW VIs which call all the functions
in the DLL.
A Java API (based on the latest driver) is available at http://www.teravation.com/products.html,
The current version supports the E functions, and the next release (available by the end
of the week) will support AOUpdate, AISample, and SHT1X from the new beta DLL.
Includes Everything for
Out-of-the-Box Operation
Everything needed (software,
screwdriver, and USB cable) is included with the LabJack U12. Installation is very simple
and takes just a few minutes:
- Connect to the USB port on a PC
running Windows 98SE/ME/2000/XP using the included cable. The low-level drivers, which
come with Windows, will be installed automatically.
- Run the LabJack installation program
to install the high-level drivers and example applications
Optional Accessories
The LabJack U12 comes complete, but
we do offer a few optional accessories.
CB25 Terminal
Board
Most of the connections on the LabJack U12 have built-in screw terminals, but 16
of the digital I/O are accessed with a DB-25 connector. To ease the use of these digital
ports the CB25 provides screw terminal connections. It also provides
short-circuit/overvoltage protection for the 16 I/O which are accessed through the DB25
connector.

IO1) to retrieve temperature and relative humidity measurements. Featuring the Sensirion
SHT11 sensor it provides 14-bit temperature readings and 12-bit humidity readings. An
enable line is provided allowing up to 20 EI-1050 probes to be connected to a single
LabJack U12. Measurement range is -40 to 120 degrees C for temperature and 0 to 100% for
humidity. Accuracy is +/-0.5 degrees C (@ 25 deg C) and +/-3.5%. With LabJack U12 firmware
version 1.10 or higher (Feb 2003 or later), it takes about 230/75 milliseconds to get a
temperature/humidity reading. With earlier firmware versions it takes about 2 seconds to
get one temperature or humidity reading.Download
