Description
1. Product Description
The GE 469-P1-HI-A20-Tis a digital motor management relay designed for industrial motor protection and control. Engineered by GE Multilin, this module offers advanced features like thermal monitoring, voltage/current protection, and communication capabilities to ensure reliable motor operation in diverse applications. The 469-P1-HI-A20-T supports customizable overload curves (standard, custom, voltage-dependent), thermal memory retention, and start inhibit functions, making it ideal for high-inertia loads and critical industrial systems. Its compact design and modular architecture simplify installation, while compliance with international standards (e.g., IEC 60255) ensures safety and compatibility.

3. Advantages and Features
- Advanced Protection: Customizable thermal overload curves (including voltage-dependent for high-inertia motors) with thermal memory retention (updated every 0.1 second).
- Reliability: MTBF > 150,000 hours (industry standard: 100,000 hours) with redundant circuitry and surge protection.
- Flexible Integration: Supports Modbus RTU and optional Ethernet/IP for remote monitoring and SCADA integration.
- Environmental Resilience: Operates in extreme temperatures (-40°C to +60°C) and harsh conditions (IP40-rated front panel).
- User-Friendly Design: Intuitive LCD interface for setup and real-time diagnostics.
4. Application Areas and Use Cases
Industries: Manufacturing (conveyor systems), energy (pumps/compressors), HVAC, water treatment.
Use Case: A water treatment plant deployed the 469-P1-HI-A20-T to protect 50+ pumps. The relay’s voltage-dependent overload protection prevented motor damage during voltage fluctuations, reducing downtime by 30%. Its Modbus connectivity enabled centralized monitoring, optimizing maintenance schedules.

6. Selection Recommendations
- Motor Type: Ideal for induction motors (1A CT input) in high-inertia applications (e.g., pumps, compressors).
- Environment: Choose for extreme temperatures or dusty environments (IP40 front panel).
- Communication Needs: Add Ethernet/IP module for SCADA integration; standard Modbus RTU suits basic monitoring.
- Budget: Balances advanced features with affordability (mid-tier pricing with enterprise-grade protection).
7. Precautions
-
Installation: Mount vertically in a clean, dry environment; avoid direct sunlight. Use shielded cables for CT inputs.
-
Voltage Surges: Install surge protectors for AC control power circuits.
-
Calibration: Verify CT ratios during setup; recalibrate after motor replacement.
-
Firmware: Update via GE’s Proficy software to access new features and security patches.
-
Maintenance: Schedule annual thermal memory reset and relay testing (contact GE-certified technicians).
