Product Overview

The UR9GH is a processor (CPU) module used in GE Multilin UR Series Universal Relays. It provides the primary computing and firmware execution environment that enables the relay’s protection, control logic, communications handling, and event/time functions. In a UR relay chassis, the CPU module is responsible for coordinating I/O processing, executing configured protection elements, and supporting engineering access for settings, monitoring, and diagnostics.

This module is applied in protection and control panels where UR Series relays are installed for feeder, transformer, motor, generator, or bus protection schemes. Because the UR9GH has a published discontinuation date, it is commonly sourced for installed-base support and maintenance replacement.
