Product Description

The USR-DR301 IoT Gateway is a robust Serial-to-Ethernet DR301 device designed for industrial applications like automation, energy management, and remote monitoring. It features 4 digital inputs and 4 relay outputs, enabling direct connectivity with sensors, actuators, and industrial control modules. The gateway supports RS232/RS485 serial interfaces and a 10/100M Ethernet port for seamless integration into existing networks. Operating on a wide DC 9-36V voltage range, it withstands harsh environments with a temperature tolerance of -20°C to 70°C. Key advantages include rugged industrial-grade design, plug-and-play functionality, and support for multiple protocols (Modbus TCP/RTU, MQTT). It lacks built-in battery backup and display, requiring external power. With compact dimensions (no integrated screen) and optimized for data transmission distances up to 100m via Ethernet, the USR-DR301 ensures reliable serial-to-IP communication in demanding IoT deployments.
