RS485 To WiFi/Ethernet Module (Modbus/MQTT Gateway)

This RS485 device data acquisitor / IoT gateway is designed for an industrial environment. It combines multiple functions in one, including serial server, Modbus gateway, MQTT gateway and RS485 to HTTPD Client.

With RS485, WiFi and Ethernet ports, the module has functions such as serial to WiFi, serial to Ethernet, Ethernet to WiFi and many others. With screw terminals for power input, it supports a 5~36V power supply. It is suitable for applications like data acquisition, IoT gateway, safety & security IoT, and intelligent instrument monitoring. With Industrial DIN Rail Mount Support, it is easy to install, has a compact size, and is cost-effective.

A power supply is not included however we stock the

recommended 12V 2A DIN-rail PSU

here.

Functions

• Rail-Mount Serial Server, RS485 to WiFi/Ethernet Module, Modbus MQTT Gateway
