Product Description
The GE Multilin UR9KH UR 9KH CPU RS485 Multi-Mode Redundant 100Base-FX Module is a high-reliability processor module designed for GE Multilin Universal Relays (UR Series) used in protection, control, and automation of electrical power systems. It serves as the central processing unit for relay logic execution, communications, and coordination with peripheral I/O and network devices. The UR9KH supports both serial and fiber-optic communication — featuring an RS-485 port coupled with a multi-mode ST fiber interface supporting redundant 100Base-FX connectivity — enabling deterministic and highly resilient networking in substation and industrial environments. This module is typically deployed in feeder, bus, transformer, motor and generator protection applications requiring robust fault detection, control logic, and integration with SCADA/DCS systems.
