Description

Brief Product Description

The General Electric UR9EV is a high-performance central processing unit designed specifically for the Multilin Universal Relay (UR) platform. It provides the advanced computational power necessary for real-time fault detection, 16-bit signal conversion, and high-speed protection logic in critical power distribution networks.

Product Description

High-Speed Computational Processing

The General Electric UR9EV functions as the primary intelligence layer for the Multilin protective relay family. This CPU processor module executes complex protection algorithms with exceptional speed, ensuring that power systems respond immediately to electrical faults. By utilizing 16-bit Analog-to-Digital (A/D) conversion and a sampling rate of 64 samples per cycle, the module captures high-resolution waveform data. This precision enables the relay to distinguish between normal transient events and actual system anomalies, thereby preventing nuisance tripping while maintaining rigorous equipment protection.

Robust Industrial Architecture

Engineers designed the UR9EV module to withstand the extreme environmental conditions typical of electrical substations and industrial facilities. The unit maintains stable operation across a wide thermal range, from -40°C to +70°C, and resists non-condensing humidity up to 95%. This internal hardware resilience ensures that the control logic remains uncompromised during seasonal temperature fluctuations or high-stress electrical events. Furthermore, the module facilitates seamless communication across the relay backplane, coordinating data from various I/O and transducer cards to provide a unified protection strategy for the entire switchgear assembly.

Seamless System Integration and Maintenance

The GE UR9EV processor features a modular form factor that simplifies both initial system configuration and long-term maintenance. Its compact dimensions allow for high-density installation within standard UR-series chassis, while the robust external housing protects the sensitive 50 kHz processing circuitry. Because this module serves as the central hub for the relay, it supports advanced diagnostic protocols and Ethernet-based communication services. These features allow maintenance teams to perform remote monitoring and rapid firmware updates, significantly reducing the time required for system commissioning and troubleshooting in the field.
