General Electric UR9EV CPU Processor Module

The GE UR9EV serves as the primary computational engine for the Multilin Universal Relay series. This high-speed CPU module manages the protection logic and control algorithms for complex power systems. It interprets high-resolution data from current and voltage sensors to detect faults instantly. By centralizing decision-making tasks, it ensures rapid response times for circuit breaker tripping and grid stabilization.

Technical Specifications and Environmental Ratings

Advanced Processing and Data Accuracy

This processor module utilizes 16-bit analog-to-digital conversion for superior signal clarity. High-speed sampling at 64 samples per cycle allows for detailed waveform analysis. Consequently, the module can identify subtle harmonic distortions and transient anomalies. This level of precision prevents unnecessary system downtime caused by false trip signals.

Furthermore, the UR9EV maintains stable performance across extreme thermal ranges. The industrial-grade components withstand storage temperatures up to +85°C. This resilience makes the module ideal for outdoor substations and unconditioned control rooms. The compact 0.96 kg footprint simplifies the installation process within high-density relay racks.

Operational Integration and Compatibility

Engineers integrate the UR9EV into existing Multilin relay chassis to upgrade system capabilities. The module supports seamless communication with various I/O and communication cards. It handles 220 V internal power requirements while maintaining high-frequency output for internal logic. This ensures full synchronization across all protective elements within the bay.

Standardized shipping dimensions of 17.2 x 4 x 18 cm facilitate easy replacement of legacy units. Because it belongs to the Universal Relay family, it benefits from a modular design. This allows users to swap the processor without replacing the entire relay housing.
