The TU846 module is used for acquiring temperature measurements from various types of temperature sensors, such as RTDs (Resistance Temperature Detectors) and thermocouples, in industrial automation and control applications. It is designed to provide high accuracy and reliability in temperature measurement.

The module supports a wide range of input signals and offers features like automatic sensor error detection and compensation, as well as built-in diagnostics for fault detection. It is typically used in process industries, such as oil and gas, chemical, and power generation, where precise temperature monitoring is crucial for process control and safety.
