Overview
UR35 overview
Core Purpose
The Milesight UR35 is an industrial cellular router designed to provide stable, long-term network connectivity for remote equipment and IoT systems. It is built to keep devices online in environments where wired networks are unreliable or unavailable. The router supports both cellular and Ethernet connections and automatically maintains connectivity when links change or fail.
Connectivity
The UR35 connects to the internet using cellular networks or wired Ethernet and can switch between links automatically to maintain uptime. Dual SIM support allows the router to change carriers when signal quality drops or a network becomes unavailable. This ensures continuous communication for critical systems without manual intervention.
Network Management
The device includes built-in routing, firewall, and traffic control features to manage data securely across connected devices. It supports secure VPN connections, allowing remote sites to safely communicate with central systems. Standard management tools such as web interface, CLI, SMS control, and centralised cloud management help simplify remote administration.
Integration and I/O
The UR35 supports serial communication and digital input/output, enabling it to connect directly to industrial controllers, metres, and sensors. This allows field equipment to transmit data over cellular networks without additional gateways. Modbus support enables straightforward integration with common industrial devices.
Power and Environmental Suitability
Designed for industrial use, the UR35 operates across a wide voltage range and functions reliably in extreme temperatures. Its metal enclosure and DIN-rail mounting support installation in control cabinets, roadside cabinets, and industrial facilities. Built-in watchdog functions help the device recover automatically from unexpected faults.
