USR-DR164 2.4/5.8GHz Dual Band RS485 to Wi-Fi Converter - Din Rail Mount
The USR-DR164 2.4/5.8GHz Dual Band RS485 to Wi-Fi Converter is an industrial-grade serial device server designed to provide seamless wireless communication between RS485 serial devices and Wi-Fi networks. Featuring dual-band Wi-Fi support (2.4GHz and 5.8GHz), the converter ensures reliable data transmission with improved speed, reduced interference, and extended communication flexibility for industrial automation and IoT applications. Its compact DIN rail mount design makes installation simple inside control panels, automation cabinets, and industrial environments.
The device supports transparent serial-to-Wi-Fi data transmission and integrates easily with PLCs, SCADA systems, sensors, meters, and industrial controllers. With support for TCP, UDP, HTTP, MQTT, IGMP, and Modbus RTU to Modbus TCP conversion, the USR-DR164 is ideal for smart factories, energy monitoring systems, intelligent transportation, and remote industrial monitoring applications. It also supports AP, STA, and AP+STA operating modes, allowing flexible network deployment options. The wide operating voltage range and industrial-grade temperature tolerance ensure stable performance in harsh environments.
