Special order, 7-14 day despatch
Labjack T7-PRO-OEM is a PCB-only version of the standatd T7-PRO. The enclosure, and most connectors are not installed on the OEM version, which allows customers to fit their own connectors themselves.
The LabJack T7-PRO 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.
The T7-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).
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-PRO has up to 6 counting inputs.
The Kipling configuration software for the T7-PRO 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.
