The GE UR7HH Multilin COMMS Module enhances UR‑series relays with fast interrelay communication using dual 820 nm multimode fiber channels. It supports efficient data exchange in protection and control systems.
Core Features
The UR7HH includes two LED‑based multimode fiber channels and three Ethernet ports that reduce latency and support IEEE C37.118 synchrophasors. It works with EnerVista software for channel monitoring, trending, and communication diagnostics.
The UR7HH supports UR‑series relays in substation automation, protection coordination, and high‑speed interrelay communication. It integrates with EnerVista tools for enhanced monitoring and system management.
Why It Matters
The UR7HH improves communication reliability through multimode fiber channels, advanced protocol support, and robust Ethernet connectivity. Its durable design and strong compatibility make it a key module for modern UR‑based protection systems.
