GE UR6EH Digital (I/O) Module

The GE UR6EH is presented in the search results with two distinct and conflicting identities: one as a Protective Relay Module and another as a Digital Input/Output (I/O) Module. This discrepancy is significant, and it is crucial to clarify which product is being discussed, as their specifications and applications are entirely different.

⚠️ 1. Identification and Product Type Discrepancy

The search results show a clear inconsistency in the description of the UR6EH:

• Most sources  describe it as an intelligent protective relay module from GE.
• Other sources  describe it as a digital input/output module.

This suggests a potential error in product listing or indexing across some websites. Given that GE’s UR series is famously known for its protective relays, the specifications for the protective relay module are more likely to be accurate. The following technical specifications will focus on this primary identity, with a note on the alternative description.

📊 2. Technical Specifications (Protective Relay Identity)

Based on the majority of the search results, the core technical specifications for the GE UR6EH protective relay module are as follows:

🛡️ 3. Protection Functions & Features

The UR6EH is designed as a comprehensive protection device:

• Multifunctional Protection: It integrates several key protection functions like overcurrent, over/under voltage, and frequency protection into a single module, simplifying system design .
• Self-Diagnostics: The module includes continuous self-monitoring to detect internal faults, enhancing system reliability and preventing false trips .
• HART Communication: This protocol allows for advanced remote configuration, calibration, and real-time monitoring of the module’s status and measurements from a control room .
• Local Interface: It features a local display for on-site viewing of status information, settings, and fault data .
• Rugged Design: With a NEMA 4X/IP66 rating, it is built to operate reliably in harsh industrial environments where it may be exposed to moisture, dust, and corrosive agents .

🔌 4. Alternative Description: Digital I/O Module

Some sources list entirely different specifications, describing the UR6EH as a Digital Input/Output Module 56. The cited advantages in these sources include:

• High Integration: Combines both digital input and output functions in one module.
• High Reliability: Uses quality components for stable operation in harsh conditions.
• Ease of Use: Simple connection and configuration via programming interfaces.
• Flexibility and Compatibility: Supports multiple signal protocols (e.g., Modbus, Profibus) and is compatible with mainstream industrial controllers.

Important Note: These specifications for a DIO module contradict the protective relay specifications and are likely a result of a product listing error. The UR6EH designation, in the context of GE’s well-established UR product line, is consistent with a protective relay.

🏭 5. Applications

As a protective relay, the UR6EH is designed for application in electrical power systems to protect critical assets, including:

• Transformer protection
• Generator protection
• Motor protection
• Switchgear protection
• Feeder protection
• Busbar protection
• Cable protection
