Case
A European industrial leader with scattered manufacturing and energy hubs struggled with inefficient energy data collection: technicians relied on laptops for on-site logging, causing delays and fragmented data that hindered optimization and compliance.
Adopting the TR-344 Industrial Router transformed their workflow. Its robust 4G/5G cellular connectivity enabled automatic, long-distance data transmission from distributed meters and sensors—eliminating laptop-dependent on-site work. The router’s compatibility with key energy protocols (e.g., DL/T 645, IEC 62056) and flexible LAN/RS485 interfaces ensured seamless integration with existing devices, while dual-core processing guaranteed stable, real-time data flow.
Now, energy data is centralized on a single platform, providing the team with holistic, up-to-date insights. Technicians focus on critical tasks instead of manual logging, and data-driven decisions drive smarter energy use and regulatory adherence. The TR-344’s industrial-grade reliability has made it a cornerstone of the company’s energy management strategy.
