- Model/Part Number: UR9VM
- Description: CPU Module with advanced processing and communication for Multilin Universal Relay series
Overview
The General Electric UR9VM is a CPU Module from the Multilin Universal Relay (UR) series, manufactured by GE and now managed by GE Vernova. It serves as the processing core for UR relays, providing high-performance computing for protection algorithms, logic processing, and communication. Compatible with UR relays like T60, G60, B30, and L90, it is used in power plants, substations, and industrial facilities for protection and control of power system assets such as transformers, generators, and feeders. The UR9VM is a newer CPU module with advanced communication features, including dual Ethernet ports.
