GE UR9HH CPU Module High-Speed Protection Processing – UR Series Universal Relay Platform
When a CPU module fails in a substation protection relay, the consequences are immediate and severe: protection functions go offline, fault detection ceases, and the entire power system becomes vulnerable to uncleared faults that can cascade into equipment damage, arc flash events, or widespread outages. In mission-critical power infrastructure — from transmission substations to industrial switchgear — the CPU module is the brain of the relay. Without it, every downstream protection function is blind.
The GE UR9HH is a high-performance CPU module designed for the GE UR Series Universal Relay platform — one of the most widely deployed protection relay architectures in global power utilities and industrial facilities. The UR9HH occupies the top tier of the UR CPU family, delivering the processing headroom required for complex multi-function protection schemes, high-speed communications, and IEC 61850 GOOSE messaging. It is specified by protection engineers on every continent where GE Multilin UR relays are the standard of record.

Frequently Asked Questions
Q: Is the GE UR9HH compatible with all UR Series relay models?
A: The UR9HH is designed for the UR Series platform, but compatibility depends on the specific relay model and chassis revision. Please contact us with your relay model number for confirmation.
Q: Can I replace the CPU module without replacing the entire relay?
A: Yes. The UR Series uses a modular architecture that allows individual module replacement. The CPU module can typically be swapped without removing the relay from service, subject to site safety procedures.
Q: Do you supply new or refurbished UR9HH modules?
A: Konmask.com sources both new-old-stock and professionally refurbished units depending on availability. Condition is clearly stated in the quotation.
Q: What firmware version does the UR9HH support?
A: Firmware compatibility depends on the specific relay model and application. We recommend consulting the GE EnerVista UR Setup release notes or contacting our technical team for guidance.
Q: How long does international shipping take?
A: Typical delivery is 5–15 business days depending on destination and shipping method. Express options are available for urgent requirements.
