GE Multilin UR-5FH Transducer I/O 5F Module

GE Multilin UR 5FH Transducer I/O Module

The GE Multilin UR 5FH is a dedicated Transducer Input/Output (I/O) module used within the Universal Relay (UR) protection and control platform. It provides high‑accuracy analog transducer inputs and outputs, enabling UR relays to interface with external measurement devices such as transducers, sensors, and analog instrumentation used in power system monitoring and control.

Hardware Specifications

Functional Description

The UR‑5FH module expands the analog measurement capability of UR relays. It is designed to interface with external transducers, allowing the relay to read analog signals such as:

• DC voltage transducers
• DC current transducers
• Power or energy transducers
• Pressure, temperature, or auxiliary analog sensors (depending on system design)

The module converts these analog signals into digital values for use by the relay’s CPU, enabling:

• Protection logic
• Control functions
• Monitoring and trending
• SCADA / automation integration

The UR‑5FH is commonly used in UR relay families such as:

• C30 / C60 Centralized I/O processors
• F35 Feeder protection
• L60 Line protection
• T60 Transformer protection
• B30 Bus differential

Its analog channels are designed for high accuracy and stability, ensuring reliable measurement in demanding utility environments.

Integration & Placement in UR Relays

The UR‑5FH installs into one of the rear modular slots of the UR chassis. Its placement is determined by the relay’s order code, where each two‑character segment (e.g., 5F, 5H) identifies the installed transducer I/O module.

Example order code segment:

• 5F → Transducer I/O module
• 5H → Variant of transducer I/O with different scaling or channel configuration

The relay’s hinged faceplate allows easy access for installation and replacement.

Typical Applications

The UR‑5FH is used for:

• Analog transducer monitoring (DC voltage, DC current)
• Auxiliary analog measurement for control schemes
• SCADA analog input integration
• Industrial process monitoring
• Power system instrumentation

Its analog channels support precise measurement required for advanced protection and control algorithms.

Frequently Asked Questions

Q: What does the UR‑5FH module do? A: It provides analog transducer inputs and outputs, allowing UR relays to interface with external measurement devices.

Q: Where is the UR‑5FH located inside a UR relay? A: Its slot position is determined by the relay’s order code. The “5F” segment identifies the transducer I/O module.

Q: Does the UR‑5FH work with EnerVista UR? A: Yes. Configuration, diagnostics, and monitoring are performed through EnerVista UR using Viewpoint Monitoring and Viewpoint Maintenance.

Field Installation Guidelines

• Ensure the module is fully seated in the UR chassis to maintain reliable analog‑signal conversion.
• Use shielded wiring for analog transducer inputs to minimize noise.
• Terminate shields at a single grounding point to avoid ground loops.
• Verify scaling and calibration settings in EnerVista UR after installation.
• Confirm connector engagement before energizing the relay.
