Compatible Replacement & Equivalent Models
The following modules are commonly evaluated as replacements or functional equivalents for the GE UR6NH. Compatibility depends on chassis type, firmware version, and application requirements — always validate before substitution:
- GE UR6NH-A / UR6NH-B – Variant suffixes indicating output configuration; confirm relay type before ordering
- GE UR6TH – Alternative I/O module in the UR6 family; verify I/O count and voltage ratings
- GE UR6AH – Analog I/O variant; not a direct digital replacement but used in mixed I/O configurations
- GE D60 / T60 / L90 Series I/O Modules – Platform-specific modules; cross-reference chassis slot compatibility
- Schweitzer SEL-2505 / SEL-2506 – Third-party I/O expanders compatible with IEC 61850 environments
- ABB RIO600 – IEC 61850 GOOSE-based I/O module; suitable for protocol-level integration in mixed-vendor substations
⚠ Important: Substitution of UR Series modules requires matching the chassis slot type (e.g., Slot H, Slot N) and firmware compatibility. Consult GE Multilin documentation or contact Konmask for pre-sales verification.
Why Choose the Original Model

- OEM Support: Eligible for GE Multilin technical support, firmware updates, and warranty coverage
- Reduced Integration Risk: Eliminates compatibility testing overhead associated with third-party alternatives
- Traceability: Full OEM documentation, test reports, and serialization for asset management compliance
Typical Applications
- Power system protection relay I/O expansion (transmission & distribution)
- Substation automation and SCADA integration
- Breaker control and status monitoring
- Motor protection relay auxiliary I/O
- Industrial process control with GE UR platform relays
- Renewable energy (wind/solar) plant protection systems
- Railway traction power protection
System Compatibility
The GE UR6NH is designed for use within the GE Multilin UR Series relay platform. Verified compatible host relays include:
- GE D60 Line Distance Protection System
- GE T60 Transformer Management Relay
- GE L90 Line Differential Relay
- GE B90 Bus Differential Relay
- GE C60 Breaker Protection Relay
- GE F60 Feeder Management Relay
- GE G60 Generator Management Relay
- GE M60 Motor Management Relay
Slot position: Slot H or Slot N (verify against your relay’s order code). Chassis firmware version must support the UR6NH module type — consult the relay’s order code and firmware release notes.
Selection Guide
Use the following decision framework to confirm the UR6NH is the correct module for your application:
- Step 1 – Identify Host Relay: Confirm your GE UR Series relay model (D60, T60, L90, etc.) and its order code
- Step 2 – Verify Slot Type: Check the chassis slot designation (H or N) where the I/O module will be installed
- Step 3 – Confirm I/O Requirements: Count required digital inputs and outputs; verify voltage levels (24V DC, 125V DC, 250V AC, etc.)
- Step 4 – Check Firmware Version: Ensure relay firmware supports UR6NH; upgrade if necessary before installation
- Step 5 – Validate Output Type: Confirm whether Form-A (normally open) or Form-C (changeover) relay outputs are required
- Step 6 – Review Standards: Confirm IEC 61850 GOOSE messaging requirements if applicable to your SCADA architecture

Replacement & Compatibility FAQ
Q: Can I use the UR6NH in any GE UR Series relay?
A: Not universally. The UR6NH must be installed in a compatible chassis slot (H or N type). Always verify your relay’s order code and slot map before ordering.
Q: Is the UR6NH compatible with IEC 61850 GOOSE?
A: The UR6NH provides physical I/O; GOOSE messaging is handled at the relay firmware level. Confirm your relay firmware version supports IEC 61850 if this is a requirement.
Q: What is the difference between UR6NH and UR6TH?
A: Both are UR Series I/O modules but differ in I/O count, output type, and slot compatibility. Contact us with your relay order code for a definitive comparison.
Q: Can Konmask source the UR6NH if it is out of stock?
A: Yes. Submit an RFQ and our sourcing team will locate verified stock from our supplier network, typically within 5–10 business days.
Q: Do you provide a warranty on used or refurbished units?
A: Yes — all Konmask-stocked units carry a 12-month warranty regardless of condition grade. Condition (new/refurbished/surplus) is disclosed at time of quotation.
