Measures thermocouples in rugged environments. FieldDAQ™ devices are dust- and water-resistant and offer TSN technology for simplified distribution.

The Temperature Input Device for FieldDAQ measures up to 16 thermocouple channels. The module features cold-junction compensation and open thermocouple detection with an LED indicator per channel to identify disconnected thermocouples. Additionally, the module incorporates Time Sensitive Networking (TSN), which provides tight synchronization over a distributed network of data acquisition nodes without additional cabling or complex programming. The device also features an integrated network switch and built-in power circuitry for simple daisy chaining.The Temperature Input Device for FieldDAQ includes the NI-DAQmx driver and configuration utility that simplify configuration and measurements. NI-DAQmx supports NI programming environments as well as Python, ANSI C, C#.NET, and MathWorks MATLAB® software.
