GE Multilin 469-P1-HI-A20-E Motor Management Relay

This motor management relay serves as a precision guardian for medium to large industrial motors. Its primary role involves real-time monitoring of critical parameters like current, voltage, and temperature while offering programmable protection against conditions like overload, phase imbalance, and ground faults. Unlike basic relays, this unit integrates advanced diagnostics and communication capabilities for predictive maintenance strategies.

Where does this relay shine? Consider a chemical plant’s centrifugal compressor system – the 469-P1-HI-A20-E would continuously analyze vibration patterns through its CT inputs while communicating status to the DCS via Modbus. For pump stations facing frequent voltage fluctuations, its wide input range (90–300 VDC) proves invaluable. We’ve seen this unit deployed alongside GE’s VMIVME modules in power generation facilities, where its diagnostic logs helped reduce unplanned downtime by 30%.

Our inventory covers both standard configurations and specialized variants like the SR469-P5-HI-A20. For legacy systems requiring backward compatibility, we maintain stocks of earlier firmware versions. Technical support includes configuration assistance through EnerVista 469 Setup software – personally, I’ve helped several customers migrate settings from older 3500 systems to this platform.
