8-Channel RS485 to Ethernet RJ45 Serial Server, 8 Channels Independent RS485 Operation, Industrial Isolated DIN-Rail Serial Module, PoE Function
Industrial, multi-functional serial device data acquisition module / IoT gateway with 8 RS485 channels and two Ethernet ports (PoE version). Small size, easy installation, and cost-effectiveness make it ideal for applications such as data acquisition, IoT gateway, security and protection IoT, and intelligent instrument monitoring, meeting diverse application scenarios.
Key features:
- 8 independent RS485 ports, each configurable with different baud rates and operating بدون помех (without interference)
- Supports TCP server, TCP client, UDP, and UDP multicast modes
- Combines multiple functions in one, including serial server, Modbus gateway, MQTT gateway, and RS485 to JSON, etc.
- Uses screw terminals for stable power supply
- Built-in dual Ethernet ports enable network switch functionality
- Multiple LEDs for real-time monitoring of device status
- Wall-mount and DIN-rail mount housing, easy to install, for rapid deployment and expansion

Industrial DIN-Rail Mount Design, Supports Wall and DIN-Rail Mounting, Compact Size, Easy Installation, Cost-Effective
Modbus Gateway Support
Suitable for upgrading Modbus networks, can be used with special configuration software.
Multiple Communication Modes
Supports TCP Server / TCP Client / UDP Multicast / UDP Mode
MQTT/JSON to Modbus
More flexible conversion between different protocols
When used as an MQTT gateway, devices can send serial data to an MQTT server using the MQTT protocol via transparent transmission. Supported servers include Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet, etc. The acquired Modbus RTU data or custom serial data can be parsed into JSON format and packaged into an MQTT data packet for transmission.
When used as a JSON data acquisition gateway, devices can be connected to data acquisition instruments via an RS485 connection, then automatically acquire data, convert it to JSON format, and finally send it to a server. The acquired data supports Modbus RTU 645 instruments version 97, 645 instruments version 07, as well as various custom RS485 protocols. The format of the uploaded data can be configured via the host, and the JSON transmission protocol can be the MQTT protocol, HTTP POST protocol, HTTP GET protocol, etc.
Protection, Safety, and Stability
Built-in power supply and signal isolation provide stable isolation voltage with high reliability and strong interference immunity. Built-in TVS (Transient Voltage Suppressor Diode) effectively suppresses surges and transient voltage spikes in the circuit, lightning protection, and ESD protection. Built-in self-resetting fuse and protection diode ensure stable current and voltage output, prevent overcurrent and overvoltage, and improve shock resistance.
