3. Main functions

✅  Signal acquisition and transmission

The TU846 terminal unit can be connected to on-site sensors, actuators, and other devices to collect analog or digital signals, and convert these signals into data formats that can be processed by the control system.

It is responsible for signal preprocessing, ensuring that the signal can be transmitted accurately and without error to the backend control system.

✅  protocol compatibility 

TU846 supports communication protocols such as Modbus, HART, Profibus, etc., and is compatible with various PLC, DCS, SCADA systems. It is widely used in industrial automation control and remote monitoring systems.

✅  Flexible I/O configuration

Provide multiple digital and analog input/output interfaces, which can be flexibly configured according to on-site needs to adapt to different equipment and system requirements.

Compatible with multiple sensors and actuators, including pressure sensors, temperature sensors, current sensors, etc.

✅  High reliability and anti-interference capability

Industrial grade design with strong anti-interference ability, able to adapt to harsh environments such as high temperature, humidity, vibration, etc.

Overload protection, short circuit protection, and high reliability components ensure long-term stable operation of the system.
