Product Overview
The GE UR8NV is an expansion analog input module for the Universal Relay (UR) series from GE Multilin (Vernova Grid Solutions). It provides high-accuracy acquisition of current signals (and in some implementations voltage via CT/VT interface) for advanced protection, metering, automation, and control applications in power systems. The UR8NV integrates seamlessly into UR relay chassis to support substations, generators, transformers, motor protection schemes, and other critical electrical infrastructure. It offers reliable performance in industrial environments with rugged design, diagnostics features, and hot-swappable capability.
