What are the differences between DTU and RTU?

DTU and RTU, then what is DTU? What is RTU, and what are the differences between DTU and RTU?

The characteristics of DTU are:

1. Rapid and flexible networking, short construction period and low cost;

2. Wide network coverage;

3. Good security and confidentiality;

4. The link supports always-on, metered billing, and low cost for users;

The characteristics of RTU are:

1. Long communication distance;

2. It is used in various industrial sites with harsh environments;

3. Modular structured design, easy to expand;

4. It is widely used in water conservancy, power dispatching, municipal dispatching and other industries with remote signaling, telemetry, and remote control.

From the above introduction, DTU is a wireless data transmission module, a terminal module for remote data transmission using 4G and 5G networks. The principle is to package serial port data into TCP or UDP packets for remote data transmission.

RTU is an analog acquisition terminal module, which is a device that converts analog variables into digital format through A/D after acquisition.

Generally, DTU can only transmit standard 232 and 485 data, while RTU can only convert analog data into serial port data after collection. DTU is a data transmission device, and RTU is a data acquisition device. The division of labor between the two is clear and easy to distinguish.
