Description
The GE Multilin UR6PH is a high-performance Digital Input/Output (I/O) module designed for the Universal Relay (UR) Series. This modular platform is manufactured by GE Vernova (formerly GE Grid Solutions / Multilin) and is engineered to provide protective relaying, control, and monitoring for critical power system assets. The UR6PH specifically functions as an interface module, offering a combination of high-speed digital inputs and metered outputs to manage substation equipment like breakers and switches.

Country of Origin
- Primary Origin: Canada (GE Multilin’s main manufacturing and R&D hub for the UR series is located in Markham, Ontario).
Application Areas
The UR6PH module is utilized across various protection and control systems within the Universal Relay family:
- Transmission & Distribution: Used in D60 (Distance) and L90 (Line Differential) relays for breaker tripping and status monitoring.
- Generation Protection: Integrated into G60 and G30 systems to manage generator lockout relays and auxiliary signals.
- Substation Automation: Works with the C30 or C60 controllers for bay control, interlocking, and Sequence of Events (SOE) recording.
- Industrial Power Plants: Provides the I/O interface for motor protection (M60) and transformer management (T60).
Product Usage Instructions
1. Installation
- Slot Selection: The UR6PH is a “hot-swappable” module designed for specific I/O slots in the UR chassis. Ensure the CPU module is configured to recognize the module in the selected slot.
- Insertion: Slide the module into the chassis guides and push firmly until the backplane connectors seat completely. Tighten the front panel captive screws.
2. Wiring
- Inputs: Wire dry contacts to the digital inputs. These are typically used for sensing breaker position (52a/52b) or external trip commands.
- Outputs: Connect the Form-A outputs to the trip/close coils or auxiliary relays. Ensure the wiring follows the polarity required for metered versions.
3. Configuration
- Software: Use EnerVista UR Setup software to map the inputs and outputs.
- Logic: Program the I/O points within the FlexLogic™ engine to define which protection elements (e.g., Overcurrent, Distance) trigger the physical UR6PH outputs.
4. Maintenance
- Use the built-in monitoring tools to check the “health” of the trip circuit. If the module features current metering, it can detect open circuits in the breaker coil before a trip is required.
