Technical Specifications

Engineering Advantages

• Sophisticated Thermal Modeling: The 469-P5-HI-A20-T utilizes an advanced thermal model that accounts for motor heating due to overload, unbalanced current, and stator cooling. This precise calculation allows the motor to operate at its maximum safe capacity without risking insulation damage.

• Versatile Power Architecture: The "HI" control power designation enables the relay to operate across a wide voltage range (90–300 VDC or 70–265 VAC). This flexibility ensures compatibility with diverse substation battery banks and industrial AC mains, simplifying global deployment.

• Unified Communication Stack: This relay supports multiple high-level protocols including IEC 61850 and DNP3. These interfaces allow the 469 to integrate seamlessly into modern SCADA and DCS environments, providing operators with real-time data streaming for predictive analytics.

• Ruggedized Environmental Performance: Engineered for the harshest conditions, the module maintains operational accuracy from –40°C to +70°C. The robust hardware resists high-vibration and electromagnetic interference (EMI) levels typically found near large motor starters and variable frequency drives (VFDs).

• Comprehensive Diagnostic Logging: The integrated LCD and historical event logs track motor trips, starts, and operational hours. Maintenance teams use this data to perform root-cause analysis on motor faults, significantly reducing the Mean Time to Repair (MTTR).

FAQs

• Q: What is the significance of the "P5" and "A20" codes in this model?

• A: The "P5" indicates 5A Phase CT secondaries, making it compatible with standard industrial current transformers. The "A20" designates the inclusion of 4–20 mA analog outputs, which allows the relay to transmit motor parameters to external PLC or DCS analog inputs.

• Q: Can this relay protect synchronous motors?

• A: Yes. The Multilin 469 series specifically supports both induction and synchronous motors. For synchronous applications, it monitors field excitation and pull-out conditions to ensure synchronized operation.

• Q: How does the "T" suffix affect the device?

• A: The "T" typically indicates enhanced features or specific environmental testing/options within the 469 family, such as enhanced communication or specific terminal configurations. This Brand New original unit meets all standard Multilin 469 high-performance benchmarks.

• Q: Does the relay support remote monitoring?

• A: Absolutely. Through the Ethernet port or RS485 interface, you can access all motor data, trip history, and diagnostic values remotely using GE’s EnerVista software or third-party SCADA systems.
