Analogue
Inputs |
|
|
The
LabJack U6 has 14 external analogue inputs (AIN0-AIN13). AIN0-AIN3
are available on screw terminals and also on the DB37 connector. All
14 analogue inputs are available on the DB37 connector.
The
maximum input range is ±10 volts, with software selectable
gains of x1, x10, and x100. Each analogue input can be measured
single-ended, or differentially in even/odd pairs. Analogue input
resolution is 16 bits at max speed (?? conversion time), increasing
to 18 bits at slower speeds (?? ms conversion time). Input impedance
is at least 1 G?, with typical input bias currents of only 10 nA.
Command/response
(software timed) analogue input reads typically take 1-4 ms
depending on number of channels and communication configuration.
Hardware timed input streaming has a maximum rate that varies with
resolution from 4 ksamples/s at 18 bits to 50 ksamples/s at 16 bits.
The
U6-Pro has all the features of the normal U6 with the addition of an
auxiliary low-speed high-resolution (24-bit) sigma-delta ADC.
Analogue input resolution varies from 19.5 bits (RMS or Effective) at
max speed (??? ms conversion time), to 22 bits at slower speeds (???
ms conversion time).
Thermocouples
It
is possible to connect thermocouples directly to the U6. The U6 has
an internal temperature sensor, which can be used for cold junction
compensation. DAQFactory contains thermocouple linearisation as a
built-in conversion function.
Fixed
Current Outputs
The
LabJack U6 has 2 fixed current outputs of 10 uA and 200 uA. These
are useful for measuring resistance and for use with resistance thermometers. |
|
|
|
Analogue
Outputs |
|
The
LabJack U6 has 2 analogue outputs (DAC0 and DAC1) that are available
both on screw terminals and the DB37 connector. Each analogue output
can be set to a voltage between about 0 and 5 volts with 12-bits of
resolution. The analogue outputs are based on a true voltage reference.
The
analogue outputs are updated in command/response mode, with a
typical update time of 1-4 ms depending on communication configuration.
|
 |
|
Digital
I/O |
|
|
The
LabJack U6 has 20 digital I/O channels which can be individually
configured as input, output-high, or output-low.
The
first 4 FIO are available on screw terminals and the DB37 connector.
All 8 FIO and 3 MIO are available on the DB37 connector, and 8 EIO
and 4 CIO are available on the DB15 connector. Note that on the U6,
CIO0-CIO2 are the same as MIO0-MIO2.
Command/response
(software timed) reads/writes typically take 1-4 ms depending on
communication configuration. The digital inputs can also be read in a
hardware timed input stream where up to 16 inputs count as a single
stream channel.
Timers
Up
to 4 digital I/O can be configured as timers. The timers are very
flexible, providing options such as PWM output, pulse timing, pulse
counting, and quadrature input.
Counters
Up
to 2 digital I/O can be configured as 32-bit counters. Since
counting is one possible mode of the timers above, the U6 has up to 6
counting inputs.

Software |
|
The
LabJack U6 is supplied with a range of software which can also be
downloaded here.
Control
Panel Application
The
LabJack Control Panel application handles configuration and testing
of the U6. When first opened it searches for connected LabJacks and
displays a list. From the Control Panel Application, it is possible
to change U6 IP addess, USB ID number and read/write all
analogue/digital I/O.
Self-Upgrade
Application
Both
processors in the U6 have field upgradeable flash memory. The
self-upgrade application programs the latest firmware onto either
processor. FREE firmware upgrade will be available from time to time
bringing improved performace and new features. |

LJLogUD
A
Ready-to-run executable logs from 1-16 channels on a U3, U6, or UE9.
Displays selected channels on a graph and writes data to file.
Executable requires the LabVIEW 6.0 run time engine (which can
coexist with other versions of the LVRTE).
Download
Here >>
The
LVRTE6 is installed by the U12 Legacy software installation, can be
downloaded here,
or can be downloaded at ni.com. Get the LJStreamUD executable here,
or for LabVIEW programmers the source code is available in the LabVIEW_LJUD
archive.

For
faster acquisitions use the ready-to-run executable which streams
analog inputs from 1-16 channels on a U3, U6, or UE9. Displays
selected channels on a graph and writes data to file. Executable
requires the LabVIEW 6.0 run time engine (which can coexist with
other versions of the LVRTE).

LJTick-InAmp
InAmp
|
Signal-conditioning
module provides two instrumentation amplifiers ideal for low-level
signals such as bridge circuits (e.g. strain gauges) and thermocouples.
Each
amplifier converts a differential input to single-ended. The LJTIA
has switches to choose from 5 gain settings (x1, x11, x51, x201, or
custom) and two output voltage offsets. The 4-pin design plugs into
the standard AIN/AIN/GND/VS screw terminal block found on the U3.

LJTick-DAC
DAC
|
Provides
a pair of 14-bit analogue outputs with a range of +/- 10 volts.
Plugs into any digital I/O block, and thus up to 10 of these can be
used per U3/UE9 to add 20 analog outputs

LJTick-Relay
Driver
Relay
|
The
LJTick-RelayDriver (LJTRD) allows 2 digital I/O lines on a U3 or U6
to each control a relay or other moderate load. The 4-pin design
plugs into the standard DIO/DIO/GND/VS screw terminal block found on
newer LabJacks such as the U3 and U6.
Each
DIO controls a switch to ground (i.e. open-collector) that can hold
off up to 50 volts and can sink up to 200 mA.

LJTick-Divider
Divider
|
The
LJTick-Divider (LJTD) is a signal-conditioning module designed to
take 2 single-ended higher voltage analogue signals, and divide them
down to 0-2.5 volt signals. The 4-pin design plugs into the standard
AIN/AIN/GND/VS screw terminal block found on newer LabJacks such as
the U3 and U6.
The
use of large resistors and a precision op-amp buffer provides an
input impedance of 1 megaohm. By adding or replacing resistors, many
other configurations are possible, as discussed in the datasheet.

LJTick-CurrentShunt
Shunt
|
The
LJTick-CurrentShunt (LJTCS) is a signal-conditioning module designed
to convert a 4-20 mA current loop input signal into a 0.47-2.36 volt
signal compatible with the LabJack U3 or U6. The 4-pin design plugs
into the standard AIN/AIN/GND/VS screw terminal block found on newer
LabJacks such as the U3 and U6.
