WideIOT · WG series industrial intelligent gateway is a high reliability industrial intelligent gateway that supports the collection of data of various industrial equipment such as PLC, instrument, water environmental protection, power equipment, CNC, and has protocol analysis and edge computing. It is the core edge node for building industrial Internet system.
WideIOT WD Series IOT Terminals are industrial wireless terminals that support IO acquisition control and serial port transparent transmission. They support data acquisition and control of multiple channels of DI, DO, AI, AO in industrial sites, and offer LoRa local networking and 4G data upload to the cloud. Thus, they realize wireless data acquisition and remote control of numerous on-site devices such as sensors, instruments, indicator lights, actuators, and main controllers.
WideIOT·WR series industrial wireless router is a network connection that supports 5G/4G/WIFI/Ethernet, etc., supports VPN networking, and provides low-latency, high-reliability, and high-security network access for field devices. input, so as to realize large-scale equipment networking applications.
The WideIOT WS-Series Industrial Switches deliver high stability,re- liability and security with easy maintenance. Featuring dual power and network redundancy, they are ideal for smart grids, rail transit,smart cities, safe city projects, new energy and intelligent manufacturing.
The WideIOT NAT Coupler is a specialized security isolation device for production networks. It supports IP renaming for unified IP planning, enables cross-segment device access via network segmentation, and effectively mitigates same-segment conflicts and broadcast storms. It is ideal for industrial networks demanding high data reliability, including those with PLCs, HMIs, CNCs, DCSs, and MES.
WideIOT Modbus Protocol Converters are industrial‑grade smart terminals that convert Modbus RTU (serial) to Modbus TCP (Ethernet). They bridge traditional serial‑based devices to modern Ethernet networks, enabling seamless integration with SCADA, MES, and cloud platforms.

Frequently asked questions about the WD240 IOT Terminals
WD240 offers up to 8AI‑4DI‑4DO and supports 12‑bit ADC, while WD140 is a basic model with 2AI‑1DI‑1DO. Choose WD240 when you need more I/O channels or higher analog resolution.
Yes, the high‑power LoRa version (30dBm) supports up to 12KM line‑of‑sight communication. It's ideal for wide‑area sensor networks in mines, farms, or water conservancy projects.
The terminal supports MQTT protocol with JSON format. For the 4G version (WD240‑G), simply configure the cloud broker address and credentials via the web interface. It can connect to WideIOT Cloud, AWS IoT, Azure, or private MQTT brokers.
Yes. You can extend Modbus RTU networks wirelessly using LoRa. The terminal works as a Modbus gateway, collecting data from serial devices and transmitting via LoRa to a central gateway (e.g., WG593).
5‑35V DC wide voltage input, operating temperature -40°C to 85°C, with industrial‑grade EMC protection. Suitable for harsh outdoor and industrial environments.
Yes, we provide MQTT JSON development interfaces and can customize data templates to match your cloud platform requirements. Contact our support for details.
Yes, it supports Modbus RTU, making it easy to integrate with SCADA, HMI, and PLC systems. It can also forward data to OPC UA servers via the cloud gateway.
