T7-Pro Multifunction Data Aquisition Unit

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.
