GE UR 67H – Digital Input/Output Communications Module | UR Series Protection Platform
Engineering Background
The GE UR Series (Universal Relay) is GE Grid Solutions’ flagship protection and control platform, widely deployed in transmission substations, generation facilities, and industrial power systems worldwide. The UR architecture is modular by design — each relay chassis accepts a defined set of plug-in modules that extend I/O capacity, communications capability, and signal processing without requiring a new relay frame. The UR 67H is a dedicated Digital Input/Output Communications Module engineered to expand the discrete signal interface of any UR-series relay, enabling high-density contact monitoring and output control within a single slot.
Product Positioning
For protection engineers managing substation automation upgrades, SCADA integration projects, or relay replacement programs, the UR 67H eliminates the need for external I/O marshalling panels by consolidating digital contact inputs and relay outputs directly on the relay backplane. It is the preferred module for applications requiring deterministic, high-speed discrete signal exchange between the protection relay and the substation control bus.

Proven Application Environments
- Transmission Substation Protection: Line, transformer, and bus differential protection schemes requiring high-count discrete I/O for breaker control, alarm annunciation, and SCADA telemetry.
- Generation Plant Control: Generator protection relays (G30/G60) where auxiliary contact monitoring of excitation, governor, and cooling systems demands expanded digital inputs.
- Industrial Power Systems: Motor bus transfer, feeder protection, and arc flash mitigation systems in petrochemical, mining, and data center facilities.
- Relay Modernization Programs: Drop-in I/O expansion for existing UR chassis during protection system upgrades, avoiding full relay replacement costs.
- IEC 61850 Substation Automation: Supplementary hardwired I/O alongside GOOSE messaging for redundant trip/close paths in digital substation architectures.
Engineering Advantages
- Modular Scalability: Slots directly into the UR chassis backplane — no external wiring harness, no additional power supply, no panel space consumed.
- Deterministic Response: Hardwired digital I/O operates independently of communications network latency, ensuring protection-grade response times for trip and close commands.
- Unified Configuration: Fully configurable via GE EnerVista UR Setup software — all I/O assignments, debounce timers, and output latch logic managed within the same relay settings file.
- Backplane Integration: Communicates over the UR internal high-speed backplane bus, eliminating inter-module wiring and reducing failure points.
- Hot-Swap Capable: Designed for field replacement without relay chassis removal, minimizing outage duration during maintenance windows.
- Long Service Life: GE UR platform modules are supported under GE Grid Solutions’ long-term parts availability program, with documented firmware compatibility across UR firmware generations.
System Architecture & Signal Flow
The UR 67H occupies a designated module slot in the UR relay chassis. On the field side, discrete contact inputs are wired to the module’s terminal block; the module’s internal optocoupler circuits convert wet or dry contact closures into logic-level signals. These signals are transmitted over the UR backplane bus to the relay’s main processor, where they are processed by the FlexLogic™ programmable logic engine and mapped to protection elements, control outputs, or SCADA data points. Output relay contacts on the module provide hardwired trip, close, alarm, or auxiliary functions back to the switchgear or control panel.
Signal Flow Summary: Field contacts → UR 67H optocoupler inputs → UR backplane bus → Main processor / FlexLogic™ → Output relay contacts → Switchgear / Control panel

Technical FAQ
Q: Is the UR 67H compatible with all UR Series relay models?
A: The UR 67H is designed for the GE UR Series modular chassis. Compatibility depends on the specific relay model and available module slots. Contact us with your relay model number for a definitive compatibility confirmation.
Q: What firmware version is required?
A: GE UR modules are generally firmware-agnostic at the hardware level; however, specific I/O features may require minimum firmware versions. We recommend running the latest GE-approved firmware for your relay model. Firmware version of the supplied module will be documented at shipment.
Q: Can this module be configured without GE EnerVista software?
A: No. GE EnerVista UR Setup is required for I/O assignment and FlexLogic™ configuration. EnerVista is available as a free download from GE Grid Solutions.
Q: Do you offer volume pricing for project quantities?
A: Yes. Volume discounts are available for orders of 5+ units. Contact support@konmask.com for a project quotation.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. For larger quantities or specific firmware requirements, lead time will be confirmed at quotation stage.
