Waveshare Rail-Mount Serial Server RS485 to WIFI/Ethernet Module, Modbus MQTT Gateway

Features
This is a RS485 device data acquisitor / IoT gateway designed for industrial environment. It combines multi functions in one, including serial server, Modbus gateway, MQTT gateway, RS485 to HTTPD Client, etc. With RS485, WIFI and Ethernet ports, the module can realize functions such as serial to WIFI, serial to Ethernet, Ethernet to WIFI and so on. Using screw terminals for power input, it supports 5~36V wide range power supply. Rail-mount V0 flame-retardant case design, small in size, easy to install. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring…
