Analogue Inputs

The LabJack T7 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 Mux80 multiplexer can expand this to to 80 single ended or 40 differential channels.

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.

Thermocouples

It is possible to connect thermocouples directly to the T7. The T7 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 T7 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 T7 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 T7 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 T7 has up to 6 counting inputs.

Kipling Software

The Kipling configuration software for the T7 provides basic test, configuration, and self-upgrade functionality in a graphical interface. The extent of the graphical interface is limited, since the software is intended as a basic tool. However, ALL T7 functionality is present within the program through the use of the register tables.

The Dashboard tab allows for simple testing in a graphical way. Change DIO from input to output by clicking the input button. Or, modify the analogue output voltage of the DAC lines with the arrow buttons. Analogue input values are displayed next to the analogue channel number.All of the values are updated about every half second on the dashboard page, and will continue unless the communication between the T7 and the computer is disrupted.

LUA Scripting for Stand-Alone Use

T7 and T7-Pro can operate without computer involvement running a LUA script. The user can now write complex control applications such as PID loops, data logging to SD card etc all from within Kipling which is then uoploaded to the T7. There are dozens of simple examples built into Kipling, so you don't have to dig around to find example code. See here for more information >>

uSD Card for Data Logging

The microSD card is only useful for people who are using scripting, since all other interactions with the T7 can be saved to the host PC hard drive. The LUA script has a host of file read/write routines included.

The T7-Pro ships with a 2GB micro SD card, RTC, and battery/battery-holder installed. The T7 has none of these, but does have the socket installed to hold an SD card.

Free Application Software

Included with the Windows installation we provide several useful applications free of charge.
