Multifunction DAQ with WiFi, Ethernet, and USB

Choose the T7 family for ultimate flexibility. With 16-bit to 24-bit analog inputs, the option to use USB, Ethernet, or WiFi, and numerous built-in firmware features, the T7 can help you accomplish nearly any data acquisition need.

It's great for acquiring signals from virtually any kind of sensor, and can serve that sensor data out through any of its 3 communication interfaces. With instrumentation amplified inputs, software selectable gain settings, dozens of digital I/O features, and a Modbus TCP front-end, the T7 is our most versatile multifunction DAQ platform. Common applications include laboratory research, industrial control and monitoring, automated testing, and prototype development. Additionally, T7 devices are capable of stand-alone operation by running Lua scripts.

Hardware Overview

Product Variations

T7-Pro vs. T7

The T7-Pro has the following additional features:
  • 802.11b/g WiFi connectivity.
  • Low-Speed and High-Resolution (24-bit) sigma-delta ADC.
  • Battery Backed RTC for stand-alone data logging.
  • Factory Installed microSD card for stand-alone data logging.

OEM Versions

The T7 and T7-Pro come in standard and OEM versions. The OEM versions are intended to be embedded in another device. They are missing the enclosure and most connectors, as it is easier to install connectors than it is to remove them. LabJack can customize the boards to add or remove hardware before shipping, for an additional fee. More information on OEM versions can be found in the OEM Versions section of the T7 Datasheet.

Other Highlights

  • Each purchase includes lifetime support
  • Actively monitored and highly informative forums where users can share ideas, ask questions, and get answers from both peers and our technical support staff
  • Free applications to configure, test, and log data to file
  • Free examples: Python, C/C++, LabVIEW[1], C#[1], Delphi[1], Java, MATLAB[1], VB.NET[1] and more
  • Modbus TCP – Use any platform that supports TCP/IP, no driver required
  • The free, cross-platform LabJack LJM Library – Extends/wraps the Modbus protocol for convenience
  • Expansion boards and accessories – Add ±10V DACs, 4-20 mA inputs, terminal boards, relay boards and more...
  • This all sounds like what I need, but why LabJack?

[1] Windows-only. See LJM library examples page for details.
