ToggleAn industrial RS485 4G DTU is a wireless communication device that enables industrial equipment to exchange data through cellular networks. It is commonly used in IoT applications where wired network deployment is difficult or unavailable.
By connecting field devices through interfaces such as módulo de comunicación 4g can transmit industrial data to remote servers, cloud platforms, or monitoring systems through 4G LTE networks.

ZHC4013 is an industrial 4G DTU designed for RS485 device communication. It supports 1-channel RS485 transparent transmission and is compatible with Modbus RTU/TCP protocol and JSON. With “remote control” as the core function, it is a highly easy-to-use industrial 4G communication module. Users can easily and quickly integrate it into their own systems to achieve remote and local control based on LTE and RS485.

Applications of the RS485 4G DTU – ZHC4013
Energy Meter and Power Monitoring
Many industrial meters and energy devices already provide RS485 Modbus interfaces, but they are often installed in locations where wired network deployment is difficult or expensive.
ZHC4013 communicates with these devices through Modbus RTU and transfers collected data to remote servers or monitoring platforms through 4G LTE.
Typical applications include:
-
Power meter remote monitoring
-
Energy consumption data collection
-
Distributed equipment status monitoring
Water and Environmental Data Acquisition
Water and environmental monitoring sites are often located in remote areas where wired communication infrastructure is unavailable or costly.
When sensors or instruments provide RS485 interfaces, ZHC4013 enables wireless data transmission through 4G networks.
Typical applications include:
-
Water level monitoring
-
Flow meter data transmission
-
Environmental sensor monitoring
-
Remote station data collection
Industrial Equipment Connectivity
In industrial automation systems, ZHC4013 works as a communication bridge between RS485 devices and remote monitoring platforms.
It supports Modbus RTU/TCP, MQTT, and TCP communication, allowing equipment data to be transmitted according to different system requirements.
Typical applications include:
-
Machine status monitoring
-
Remote equipment maintenance
-
Industrial IoT data collection
-
Distributed automation systems
IoT Platform Integration
ZHC4013 is designed to integrate with existing IoT platforms or customer-developed servers without requiring a proprietary cloud platform.
With support for Modbus RTU/TCP, JSON, and MQTT communication, together with features such as heartbeat packets, registration packets, scheduled reporting, and remote configuration, ZHC4013 simplifies the deployment and management of distributed IoT devices.
Conclusión
RS485 4G DTU provides a practical way to connect RS485 industrial devices to remote monitoring systems through 4G networks. With support for Modbus, MQTT, JSON, and remote configuration features, it helps simplify wireless deployment for distributed industrial IoT applications.
