GE UR-9HH CPU Module – High-Performance Central Processing Unit | GE Multilin UR Series Protection & Control Platform
Engineering Background
The GE Multilin UR Series represents GE Grid Solutions’ flagship platform for protection, control, and monitoring of electrical power systems. Designed for utility-grade and industrial substation environments, the UR platform integrates protection, control, metering, and communications into a single modular chassis. The UR-9HH is the high-specification CPU module that serves as the computational core of the UR chassis, executing protection algorithms, managing inter-module communications, and interfacing with SCADA/DCS systems.
Product Positioning
The UR-9HH CPU module is engineered for mission-critical applications where processing speed, deterministic response, and communication redundancy are non-negotiable. It is the preferred choice for transmission protection, generator protection, bus protection, and transformer differential schemes in high-voltage substations and industrial power systems. Procurement engineers specifying UR-series upgrades or replacements will find the UR-9HH fully backward-compatible within the UR chassis ecosystem.

Engineering Advantages
- High-Speed Processing: The “HH” designation indicates the highest processing tier in the UR CPU lineup, enabling sub-cycle protection response times critical for high-speed bus and line protection.
- Protocol Versatility: Native IEC 61850, DNP3, and Modbus support eliminates the need for protocol converters in mixed-vendor SCADA environments.
- Chassis Compatibility: Hot-swappable within powered UR chassis (with appropriate firmware); minimizes maintenance downtime.
- Cybersecurity: Supports role-based access control (RBAC) and encrypted communications per NERC CIP compliance frameworks.
- Integrated Time Sync: IRIG-B and IEEE 1588 PTP support ensures microsecond-accurate event timestamping for post-fault analysis.
- Long Service Life: GE Grid Solutions provides extended support lifecycle for UR platform modules, protecting capital investment.
System Architecture & Signal Flow
Within the UR chassis, the UR-9HH CPU module occupies the designated CPU slot and communicates with I/O modules (analog inputs, digital I/O, CT/VT interfaces) via the high-speed UR backplane bus. Protection algorithms execute in real-time on the DSP core, while the RISC core manages HMI, communications, and settings management. Front-panel Ethernet provides local EnerVista configuration access; rear Ethernet ports connect to station LAN/WAN for SCADA integration. IRIG-B or PTP time synchronization is received via the CPU module and distributed to all chassis modules.

Technical FAQ
Q: Is the UR-9HH compatible with all UR chassis sizes?
A: The UR-9HH is designed for the UR Series modular chassis. Compatibility depends on chassis generation and firmware revision. Contact Konmask with your chassis model for confirmation.
Q: Can the UR-9HH be upgraded in the field without chassis replacement?
A: Yes. The UR CPU module is a field-replaceable unit (FRU). Settings can be backed up via EnerVista software and restored to the replacement module.
Q: What firmware version is supplied?
A: Firmware version is confirmed at time of quotation. Konmask can supply units at specific firmware revisions upon request.
Q: Do you provide IEC 61850 SCL/CID configuration files?
A: Available upon request for units with confirmed IEC 61850 firmware. Contact our technical team.
Q: What is the lead time for the UR-9HH?
A: Typically 3–7 business days for in-stock units. Contact us for current availability.
