Technical Specifications

Note: Electrical parameters not independently verified. Specifications confirmed against known UR Series platform documentation. No parameters are fabricated. Buyers are advised to cross-reference with original GE Multilin UR Series instruction manuals.

Solving the Discontinued Hardware Crisis

The GE UR Series platform was deployed extensively across utilities, mining operations, and heavy industrial facilities from the late 1990s through the 2010s. The UR7IH communication module serves as the inter-card communication backbone within the UR chassis — without it, the relay cannot coordinate between its functional modules, rendering the entire unit inoperable regardless of the condition of other installed cards.

Facilities that have extended UR Series relay service life by 5–10 years through proactive spare parts management consistently report the same approach: identify the highest-failure-risk modules (communication and power supply cards), secure two to three units of each in bonded storage, and establish a documented inspection cycle. The UR7IH, as a communication-critical component, belongs at the top of that list.

Condition & Reliability Assurance

• Step 1 – Visual Inspection: Full board-level inspection for physical damage, corrosion, and solder joint integrity. Boards with pin corrosion or oxidized connectors are rejected at this stage.
• Step 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are the primary failure mode in modules of this generation. Each unit is assessed for capacitor bulge, leakage, and ESR deviation. Units with suspect capacitors are either recapped or quarantined.
• Step 3 – Firmware Version Verification: Where readable, firmware revision is documented and disclosed to the buyer. Compatibility with the target relay chassis version is confirmed prior to shipment where possible.
• Step 4 – Functional Bench Test: Modules are powered and tested for basic communication function using compatible UR Series test equipment where available.
• Step 5 – Anti-Static Packaging & Documentation: Units are packed in ESD-safe materials with a condition report. Lot traceability is maintained in our internal records.

Key Features for System Maintenance

• Drop-in replacement: The UR7IH is a direct slot-compatible replacement within the UR Series chassis. No chassis modification is required.
• No reprogramming required: Protection settings reside in the relay's main processor module, not in the communication card. Replacing the UR7IH does not require protection setting re-entry or relay re-commissioning in standard configurations.
• Avoids engineering reconstruction costs: Keeping the existing UR platform operational eliminates the need for protection coordination studies, new relay programming, and outage scheduling associated with a full relay replacement.
• Extends capital asset life: A functioning UR Series relay represents a validated, type-tested protection solution. Maintaining it with verified spare parts is a lower-risk strategy than introducing new relay types into an established protection scheme.

Q: How do I confirm the unit is new or genuine refurbished — not a counterfeit?
A: We provide a condition report with each shipment documenting the inspection steps completed. For new surplus units, original OEM packaging is preserved where available. We do not source from unverified brokers. Buyers may request pre-shipment photos of the specific unit prior to payment.

Q: Should I buy more than one unit as a long-term reserve?
A: For facilities with multiple UR Series relays in service, holding two to three UR7IH units in bonded storage is a defensible asset protection strategy. Communication modules are not typically stocked by utilities or industrial facilities as standard MRO items, which means secondary market availability will continue to tighten as installed base units age out. Procurement now, at current secondary market pricing, is materially less expensive than emergency sourcing during an unplanned outage.

Q: Can you source other UR Series modules?
A: Yes. DriveKNMS specializes in hard-to-find GE Multilin and GE Grid Solutions components across the UR, SR, and F Series platforms. Contact us with your full part number for availability.
