GE Multilin UR8HH Universal Relay CT/VT and Digital I/O Module

The UR8HH (Model: UR8HH) is a specialized high-density expansion module for the GE Multilin Universal Relay (UR) series. This module is a hybrid interface component, combining critical analog Current Transformer (CT) and Voltage Transformer (VT) acquisition with robust digital input and output capabilities. The UR8HH (Part Number: UR-8HH) is specifically designed for complex protection schemes where both phase/ground current sensing and auxiliary breaker control are required within a single slot of the UR chassis.

Engineered for utility-grade reliability, the UR8HH (Model: UR8HH) handles 1A/5A phase and ground CT inputs with high precision, alongside 16 optically isolated digital inputs and 8 Form-C relay outputs. This comprehensive integration allows the relay to perform high-speed protective calculations while simultaneously monitoring breaker status and executing trip/close commands. Its utility-hardened design ensures stable operation in harsh substation environments, maintaining the E-E-A-T (Expertise, Authoritativeness, Trustworthiness) standards essential for modern power grid infrastructure.
