Product Overview

The GE UR9EH is an advanced Central Processing Unit specifically engineered for the Multilin Universal Relay (UR) platform. Acting as the high-speed computational core of the system, this module is tasked with executing complex protection algorithms, managing automated control logic, and overseeing comprehensive power system monitoring. It provides the sub-cycle processing speeds necessary for mission-critical electrical infrastructure, ensuring that fault detection and isolation occur with surgical precision to protect high-value assets.

Built on a powerful 32-bit ARM Cortex-M7 architecture, the UR9EH manages the simultaneous processing of digital and analog data streams from across the relay chassis. Its modular nature allows it to serve as a scalable solution for utility substations, industrial power plants, and renewable energy sites, providing a deterministic environment for high-speed protective relaying.

Advanced Communication and Ruggedized Design

The UR9EH stands out in the Multilin family for its expansive communication suite, which facilitates seamless data transparency between the field level and the enterprise SCADA layer. The dual Ethernet architecture ensures that safety and control data remain uninterrupted even in the event of a single network path failure. This makes the UR9EH an ideal choice for modern Smart Grid applications and IEC 61850 based automation architectures.

Beyond its computing power, the UR9EH is physically hardened to withstand the electromagnetic interference (EMI) and vibration levels common in high-voltage switchgear environments. Its wide temperature tolerance ensures that it remains reliable in unconditioned remote cabinets, minimizing the need for active cooling and reducing overall maintenance overhead. By integrating the UR9EH into a Multilin system, facility operators gain a future-proof control core capable of adapting to evolving grid requirements while maintaining the highest levels of system reliability.
