USB or Ethernet multifunction DAQ device with 14 analog inputs (16- to 18- bit), 2 analog outputs (12-bit), 23 digital I/O, and up to 10 digital counters/timers.
Choose the T7 series for ultimate flexibility. With 16 to 24-bit analog inputs, the option to use USB, Ethernet, or WiFi, and numerous built-in firmware features, the T7 Series can help you accomplish nearly any data acquisition need.
It's great for acquiring signals from virtually any kind 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 Series is our most versatile multifunction DAQ platform. Common applications include laboratory research, industrial control and monitoring, and prototype development. Additionally, the T7 series devices are capable of stand-alone operation by running Lua Scripts.
More technical specifications about the T7 can be found in Appendix A of the T7's Datasheet.
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.

LJLogMLJLogM is an application that allows data to be collected at variable rates from a T7/T7-Pro and saved to a .csv file. This logging program should be used when collecting data slower than 100Hz. Simple scaling equations can be used to apply mathematical filtering to the values before they are graphed & logged to a file. |
|
LJStreamMLJStreamM is an application that uses the T7/T7-Pro's streaming functionality to collect data at high rates to graph and save the data to a .csv file. This logging program should be used when collecting data faster than 100Hz. Simple scaling equations can be used to apply mathematical filtering to the values before they are graphed & logged to a file. |

T7 microSD Card UtilityThe T7 microSD Card utility is an application that connects to T7/T7-Pro devices to allow files saved to installed microSD cards to be downloaded with out having to remove the microSD card from the device. This allows files that were created by Lua scripts to be downloaded. |
Applications compatible with the T7 are installed by the LJM Library installer. Check the installer's download page for more details.
