Product Overview

The UR8HH (Model: UR8HH) is a high-density, multifunctional expansion module designed for the GE Multilin Universal Relay (UR) series. This module acts as a critical hybrid interface, integrating analog Current Transformer (CT) acquisition with high-capacity digital inputs and outputs. The UR8HH (Part Number: UR-8HH) is specifically engineered for utility-scale protection schemes, allowing a single chassis slot to manage phase/ground current sensing alongside auxiliary breaker control and status monitoring.

Built for the rigorous transients of substation environments, the UR8HH (Model: UR8HH) features 16 optically isolated digital inputs and 8 Form-C relay outputs. This consolidated architecture enables the protective relay to execute sub-cycle trip commands while maintaining real-time awareness of field contact states. The module's utility-hardened design ensures electromagnetic compatibility and reliable performance in mission-critical grid infrastructure.

Core Application Scenarios

The UR8HH (Part Number: UR-8HH) is typically deployed in the following power system protection roles:

Feeder Protection: Measuring phase currents while providing ample I/O for breaker interlocking and trip/close coils.
Transformer Monitoring: Managing CT inputs for differential protection zones and monitoring tank pressure/temperature via digital inputs.
Breaker Control: Serving as a high-density I/O interface for dual-breaker configurations within a single relay.
Bus Protection: Providing the necessary CT sensing and lockout relay outputs for busbar protection schemes.
