T4 Multifunction DAQ Device


Choose the T4 for low cost Ethernet connectivity and the same software API as our flagship T7 device.

USB or Ethernet multifunction DAQ device with up to 12 analog inputs or 16 digital I/O, 2 analog outputs (10-bit), and multiple digital counters/timers.


The T4 has 4 dedicated high voltage (±10V, 12-bit resolution) as well as up to 8 configurable low voltage analog inputs (0-2.5V, 12-bit resolution). The T4 also has numerous built-in firmware features to help users accomplish most data acquisition needs.

The T4 is much like its bigger brother, the T7, in that it supports the LJM driver (and many other software options) for easy cross-platform programming (Windows, Mac OS X / macOS, Linux and various ARM-based Linux distributions), Modbus register access to every device attribute and the ability to run on-board Lua scripts using Kipling. The T4 also includes the same Ethernet communication interface that the T7 supports (allowing for two clients to be simultaneously connected) and is a Modbus TCP/UDP server. The T4 differentiates itself from the T7 by incorporating many popular features from the U3-HV such as high and low voltage analog inputs and flexible I/O lines. Finally, the T4 sells for much less than the T7.

  • 4 dedicated high voltage analog inputs (±10V, 12-bit resolution)
  • 8 configurable low voltage analog inputs (0-2.5V, 12-bit resolution) that can function as digital I/O lines
  • 8 dedicated digital I/O lines (EIO4-EIO7 and CIO0-CIO3)
  • Multiple timers and counters (Pulse Timing, PWM Output, Quadrature Input, ...)
  • Digital I/O lines support SPI, I2C, 1-Wire, and UART (Master modes only)
  • 2 Analog Outputs (10-bit, 0-5 volts)
