Description
The UR-9GH is a CPU of the 9G model used in many of the universal relays of the Multilin GE UR series. The different CPU parts can be classified in terms of old and new models. In this case, the UR-9GH, is a new model that is described as having a RS485 and a 10Base-F with Ethernet, Modbus TCP/IP, and DNP features.
The older model with these similar features is the 9C model of CPUs. Some new model designations, such as the 9J, 9K, 9L, 9M, 9N, 9P, 9R, and 9S modules, do not have preexisting old CPU options with their similar characteristics. For example, the 9N CPU is the only module CPU that has the RS485 and the 10/100Base-T features.
If a new CPU is paired with an old version of the CT/VT module then the universal relay will display an error code showing that the hardware options do not function together properly. However, all of the other hardware options for other I/O modules can function with the new hardware (for the CPU and for the CT/VT modules). Firmware versions may also designate if the new or the old versions will be compatible in the UR system as a whole.

The UR9GH continuously monitors internal operating conditions and maintains critical relay settings, event records, oscillography files, and fault data. Its architecture enables integration with SCADA systems, substation automation networks, and advanced grid management applications.
The UR9GH is widely deployed in power generation facilities, electrical substations, transmission networks, distribution systems, petrochemical plants, mining operations, and heavy industrial power systems.
- Substation Automation: Central hub for SCADA/DCS integration enabling remote monitoring and control
- Transformer Protection: Manages CT/VT inputs and executes relay logic for fault detection and isolation
- Generator/Motor Protection: Provides thermal modeling, monitors abnormalities, and executes high-speed tripping
- Transmission/Distribution: Supports differential, distance, and phase comparison protection algorithms

Chassis & Case: Universal Relays use a drawout case. Install the empty case into the switchgear panel cut-out using the provided mounting hardware. Securely torque all hardware to factory specifications.
Grounding: Connect the main ground terminal on the back of the case to the main grounding system. Keep all ground leads as short as possible to minimize electromagnetic interference.
Module Insertion: Carefully insert the UR 9GH CPU module into the assigned rear slot. Fasten the module's front faceplate screws tightly to ensure proper backplane connection and chassis grounding.
