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

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.

Digital Temperature/Humidity Probe. The EI-1050 uses two digital lines
on the LabJack U12 (IO0 and 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.
