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 * Offers an RS485 device data acquisitor / IoT gateway * Designed for industrial environment * Socket Distribution Protocol: In the transparent transmission mode, the serial device can send data to the specified socket link; the network data of each Socket is sent to the serial device through the serial port. * Multi Configuration Methods: supports multi-configuration methods such as hosts, web browsers and serial port configuration * Hardware Protection: ESD Level 4 Static Protection, Level 3 Surge Protection and EFT Level 3 Electrical Fast Transient/Burst Protection * Suitable for applications like data acquisition and IoT gateway * Power Supply: 5 ~ 36 V DC * DIN Rail Mount for easy installation What's On Board Specifications OUTLINE Communication interface RS485, screw terminal Power supply 5 ~ 36V DC, screw terminal Case PC + ABS, V0 flame retardant grade Dimensions L × W × H: 109.66 × 28 × 64.71 mm COMMUNICATION Ethernet 10 / 100M auto-negotiation RJ45 connector WIFI 802.11b/g/n compliant Serial port RS485 interface (Anti-surge, Lightningproof, Over-current protection) WIRELESS SPECIFICATION Frequency Band 2.412 ~ 2.484 GHz Wireless network Station / AP / AP+Station Mode Security mechanism WPA-PSK / WPA2-PSK Encryption type TKIP / AES Transmitting power 802.11b: +19dBm (Max.@11Mbps) 802.11g: +18dBm (Max.@54Mbps) 802.11n: +17dBm (Max.@HT20, MCS7); +17dBm (Max.@HT40, MCS7) Receiving sensitivity 802.11b: -89dBm (@11Mbps) 802.11g: -81dBm (@54Mbps) 802.11n: -73dBm (@HT20, MCS7); -71dBm (@HT40, MCS7) SERIAL SPECIFICATION Baud rate 300 ~ 460800 bps Parity bit none, odd, even, mark, space Data bit 5 ~ 9 bits Flow control N/A SOFTWARE Protocol TCP / UDP / ARP / ICMP / DHCP / DNS / HTTP / MQTT Configuration host, web browser, serial AT command Communication method TCP/IP direct communication, VCOM Operating mode Transparent transmission, serial command, HTTPD Client, Modbus TCP to Modbus RTU ENVIRONMENT REQUIREMENT Operating temperature -40℃ ~ 85℃ Storage temperature -45℃ ~ 125℃ Humidity range 5% ~ 95% relative humidity Resources
