GE Multilin UR8NH Universal Relay 8-Channel CT/VT Analog Input Module

The UR8NH (Model: UR8NH) is a high-performance Current Transformer/Voltage Transformer (CT/VT) interface module designed for the GE Multilin Universal Relay (UR) series. As a critical data acquisition component, the UR8NH (Part Number: UR8NH) provides the relay with 8 standard CT/VT channels, enabling high-fidelity measurement of primary power system parameters. This module is essential for protection, monitoring, and metering applications in utility substations and heavy industrial plants, ensuring that the relay has the precise analog data required for complex protection algorithms.

Designed with the modularity of the Universal Relay platform in mind, the UR8NH (Model: UR8NH) allows for streamlined hardware upgrades or the replacement of legacy modules. It features advanced onboard diagnostics that continuously monitor the health of the transformers and internal A/D converters. By converting high-level secondary currents and voltages into digital signals for the relay’s processor, the UR8NH maintains the E-E-A-T (Expertise, Authoritativeness, Trustworthiness) standards necessary for maintaining the stability and safety of critical power infrastructure.
