RS232/485 To WiFi/Ethernet Module (Modbus/MQTT Gateway)
This serial server combines functions like a serial server, Modbus gateway, and MQTT gateway, and also enables serial port data to be converted to HTTPD Client. With interfaces for RS232, RS485, WiFi, and Ethernet, it supports various data transfer methods, including from serial port to WiFi and Ethernet to WiFi.
It includes multiple power supply interfaces, accepting a wide range of 6~36V, and has an optional PoE function. Its metal case allows for both wall-mount and rail-mount installations and its compact size makes it easy to install. It is ideal for data acquisition and serving as an IoT gateway in safety and security projects.
We also stock a PoE version here
Note: The power supply is NOT included, it is recommended to use this 12V Power Adapter
