Description
Industrial Isolated 2-CH RS485 To RJ45 Ethernet Gateway
2-CH RS485 To Ethernet, Modbus/MQTT/JSON Support, Din-Rail Mount, Metal Case
Features At A Glance
This is a 2-CH RS485 data acquisition / IoT gateway device designed for industrial environment. The two RS485 channels can run simultaneously without mutual influence. It combines multiple functions in one: serial server, Modbus gateway, MQTT gateway, RS485 to JSON, and network switch. The module features two RS485 ports and two Ethernet ports (PoE function is optional), uses DC port (outer diameter: 5.5mm, inner diameter: 2.1mm) and screw terminal for power input. Enclosed in a rail-mount case, compact size, easy installation and cost-effective. It is suitable for applications such as data acquisition, IoT gateway, safety & IoT, intelligent instrument monitoring.

Basic Function
Bidirectional transparent transmission between RS485 and Ethernet
Multiple Power Supply Options
Supports PoE network port power supply*, complies with IEEE 802.3af PoE standard
Supports screw terminal and DC port for power input, 6–40V DC wide voltage range input
* This feature is only available for the PoE version
Supports Ethernet Port Cascading
Onboard 2-channel Ethernet ports for communication and cascading
One of which can be used for network serial server communication, and the other can be used for cascading or connecting to other devices
* Note: Each module in the cascade must have a separate power supply. The working current of the module is 12V/150mA (MAX), and can be cascaded up to 8.
Supports Din-Rail Mount
Industrial grade rail-mount design, compact size, easy installation, cost-effective
Modbus Gateway Support
Suitable for Modbus networking upgrade, can be used with corresponding configuration software
Multiple Communication Modes
Supports TCP Server / TCP Client / UDP Multicast / UDP Mode
* Note: This module is a dual channel, and each channel supports the above functions independently
MQTT/JSON To Modbus
More flexible conversion between different protocols
When used as an MQTT gateway, devices can upload serial port data to the MQTT server through the MQTT protocol via transparent transmission. Supported servers include Baidu Cloud MQTT, Alibaba Cloud MQTT, China Mobile OneNet and others. The received Modbus RTU data or non-standard serial port data can be parsed in JSON format and packaged into an MQTT data packet for uploading.
When used as a JSON data acquisition gateway, devices can be connected to data acquisition instruments through RS485 connection, then automatically collect data, convert data into JSON format, and finally publish them to the server. The received data supports Modbus RTU 645 version 97 instrument, 645 version 07 instrument, as well as various non-standard RS485 protocols. The uploaded data format can be configured through the host, and the JSON upload protocol can be MQTT protocol, HTTP POST protocol, HTTP GET protocol, etc.
Supports Multi-Host Polling
Different network devices will be identified and respond accordingly,
No more cross-talk problems when communicating with multiple network devices
Custom Heartbeat / Registration Packet
Easy for cloud communication and device identification
NTP Protocol Support
Obtain network time information for serial output or data upload
Multiple Configuration Methods
Supports web browser configuration, obtain dynamic IP address through DHCP,
DNS protocol to connect to domain server address
Multiple Protections, Safe And Stable Operation
Onboard power isolation and signal isolation, can provide stable isolated voltage with high reliability and strong anti-interference. Built-in TVS (Transient Voltage Suppressor) tube, can effectively suppress surge voltage and transient peak voltage in the circuit, lightning proof and anti-ESD. Built-in resettable fuse and protection diode, ensures stable current and voltage output, prevents over-current and over-voltage, improves shock resistance performance
