Product Overview

The GE Multilin UR8FH is a measurement input module for the Universal Relay (UR) platform, used to interface field instrument transformers with relay metering and protection functions. It accepts secondary CT and VT signals, scales them to the relay’s internal measurement domain, and supports accurate acquisition of phase current, ground current, and voltage values required for protection, control, and monitoring.

UR8FH is typically applied where a UR relay must be equipped with dedicated current and voltage input hardware for feeder, transformer, generator, or bus protection schemes. This model is discontinued (Dec 31, 2018) and is commonly sourced for installed-base maintenance and direct replacement needs.
