Description
Waveshare 21968 Rail-Mounted Serial Server, RS485 to WiFi/Ethernet Module, Modbus MQTT Gateway
RS485 device data acquisition device/IoT gateway for industrial environments. It combines multiple functions in a single device, including a serial server, Modbus gateway, MQTT gateway, RS485 to HTTPD client, and more. Equipped with RS485, Wi-Fi, and Ethernet ports, the module can implement functions such as serial-to-Wi-Fi, serial-to-Ethernet, and Ethernet-to-Wi-Fi. With screw terminals for power supply, it supports a wide voltage range from 5 to 36 V. The flame-retardant, rail-mountable (V0) housing is compact and easy to install. It is suitable for applications such as data acquisition, IoT gateway, security IoT, and intelligent instrument monitoring.
