Isolated, Simultaneous, High Speed Analog & Digital Measurements
The LabJack T8 is our 2022 new flagship device, capable of collecting signals from virtually any kind of sensor. With instrumentation amplified inputs, software selectable gain settings, many digital I/O features, and a Modbus TCP front-end, the T8 is our most versatile multifunction DAQ platform. Common applications include sampling large industrial signals requiring electrical isolation and/or precision timing including EV battery testing, industrial control and monitoring, automated testing, and prototype development. Additionally, T8 devices are capable of stand-alone operation by running Lua scripts and include 5x more space for Lua scripts than other T-Series devices.

T8 Analog Outputs
- 2 analog outputs (16-bit, 0-10V)
- Waveform generation via Stream Out
- Source Impedance/Load Current compensated up to 20mA
- Vout Min -0.0 Vout Max 10.0
The DACs on the T8 use additional power systems to output voltage levels above and below the supply. This allows the T8 to output approximately -0.1 to 10 V as long as the supply voltage is within the valid operating range.
The DACs on the T8 have good load regulation. Very little voltage drop is expected up to 20mA, usually 1-2 mV.
