4G DTU module

With the development of Internet of Things technology, the requirements for wireless transmission of various applications are gradually changing. The demand for wireless modules is also increasing with the market, and more and more industries are beginning to use 4G DTU modules .

What is 4G DTU module

4G DTU module refers to a terminal device that uses local serial port data to realize wireless long-distance data transmission using the operator’s 4G network and interacts with remote public network servers. It is mainly used for remote data collection and remote control projects.

Functional features of 4G DTU module

The general 4G DTU module provides an RS232/RS485 serial communication interface to realize two-way transparent transmission of serial data through the 4G network. The ZHC4012 of Zongheng Intelligent Control is a cost-effective 4G DTU module. It has full 4G network connectivity and is backward compatible with 3G/2G networks. It adopts Modbus RTU /TCP protocol and supports customized registration packages and heartbeat packages. It also supports automatic collection and active reporting. Multiple detection mechanisms, reconnection after disconnection, data retransmission, stable and reliable transmission without packet loss. Industrial-grade metal shell, durable and reliable, high EMC electromagnetic compatibility, high and low temperature resistant, moisture-proof and lightning-proof.

Advantages of 4G DTU module

The coverage of 4G network is very comprehensive. Even in rural areas of China, 4G signals can be received in most places. The high data rate transmission of 4G can also provide guarantee for server interaction. Moreover, 2G network withdrawal has become a general trend, so 4G is the best choice.

When an abnormality occurs in the 4G network, the 4G DTU module will automatically switch to other network frequency bands 2G/3G to continue to provide data transmission for users and ensure stable data transmission.

Application scenarios of 4G DTU module

The 4G DTU module can be used for remote intelligent meter reading, intelligent charging piles, water conservancy monitoring systems, environmental monitoring systems, industrial control fields, etc. It provides help for information and industrial integration between various industries, and has gradually developed into the Internet of Things. The core terminal device of the application.
