HF ElfinEW11A0 Whole Set RS485 to WiFi Serial Server, Mini Industrial Wireless Networking Device with RJ45 Port, Modbus TCPIP Supported, STA/AP/STA+AP Mode for PLC Sensor Industrial IoT Application

HF ElfinEW11A0 is a minisize industrialgrade RS485toWiFi serial server whole set, designed to connect legacy RS485 serialport equipment to WiFi and Ethernet IP network for industrial IoT data acquisition and remote monitoring. It supports Modbus TCPIP protocol, implementing bidirectional transparent transmission between Modbus RTU serial devices and TCPIP network system, perfectly matching PLC, modbus sensors, instrument meters and automation control hardware.

This wireless networking unit supports STA, AP and STA+AP mixed working modes. Users can configure parameters via builtin embedded web server or SmartLink smartconfig function, no complicated software installation required. It adopts widerange 536V DC power supply, adapts to various industrial powersupply environments. The working temperature covers 20 to +70, capable of stable operation in factory workshops, outdoor cabinets and other complex industrialscene environments

The complete wholeset includes external WiFi antenna, RS485power hybrid cable and DINrail mounting carrier, supporting direct installation on standard DIN rail. Multiple LED indicator lights display power, network and serialport communication status for quick fault diagnosis. It supports mainstream TCP, UDP, DHCP, DNS and other complete TCP/IP protocol stacks, with AES encrypted transmission function to enhance datacommunication security

It is widely applied in industrial automatic control, remote equipment monitoring, sensor data collection, UPS monitoring and smartbuilding projects. It helps users transform traditional wired serialport devices into networkconnected IoT terminals without modifying original field hardware.
