LabJack T8
The LabJack T8 is a USB and Ethernet DAQ with eight individually isolated, simultaneously sampled 24-bit inputs at up to 40 kS/s per channel, each with its own amplifier. It suits power measurement, battery stacks and load cells, where channels sit at different ground potentials or need to stay phase-aligned.

Isolated, simultaneous inputs
Each of the T8’s eight differential inputs is galvanically isolated from the main ground and from every other input, and LabJack’s comparison table rates channel-to-channel isolation at 1 kV. One channel can read a signal referenced to earth while the next reads a cell sitting at a high common-mode voltage. All eight are sampled at the same instant, so voltage and current pairs line up without skew correction. Each channel has its own range setting, from ±11 V down to ±0.075 V in nine steps.
Rates and resolution
The T8 streams at up to 40 kS/s per channel, 320 kS/s total. Resolution is 24 bits nominal, with 15 to 22 effective bits depending on the resolution index, and one resolution index applies to every channel. The two analog outputs are 16-bit with a range of about -0.1 to 10 V and up to 20 mA of drive. There are 20 digital I/O lines with LabJack’s DIO extended features, power over Ethernet is built in, and Lua scripts run on the device. The list price is $1,400 at the time of writing.
Software
Like the T4 and T7, the T8 runs on LJM, which supports Windows, macOS and Linux, and Kipling works on all three. LJLogM and LJStreamM are Windows only. LabJack T7 on a Mac covers an LJM install that applies to the T8 as well. DAQAtlas, which is in development, reads the T8 through LJM and can record it on one timeline with other devices. Synchronizing multiple DAQ devices covers what a shared timeline can and cannot align across separate hardware.
Questions
Does the LabJack T8 work on macOS and Linux?
Yes. The T8 uses LJM, which LabJack supports on Windows, macOS and Linux, and Kipling runs on all three.
Is the T8 sample rate per channel?
Yes. The T8 samples all eight inputs simultaneously at up to 40 kS/s each, 320 kS/s in total.
Are the T8 inputs isolated?
Yes. Each analog input is individually isolated, and LabJack lists 1 kV channel-to-channel isolation.
