GE FANUC 469-P5-HI-A20-T Motor Management Relay

Description

The GE FANUC 469-P5-HI-A20-T Motor Management Relay is part of the 469 motor management relay series, designed to provide comprehensive motor protection, monitoring, and control for industrial applications. Key technical specifications include a control power range of 90-300VDC and 70-265VAC at 48-62Hz, and 1 A phase CT secondary phase current input. It features four 4-20mA analog outputs for transmitting critical operational data to external systems.

This relay is equipped with a DeviceNet communication option, which includes three connection ports with 5-pin Phoenix connectors, support for 125K, 250K, or 500K baud rates, and compliance with the DeviceNet protocol, as detailed in the GEK-106491C communication guide. The model’s “T” designation indicates integrated enhanced Ethernet capabilities, with an Ethernet port on the relay rear, requiring an SR469 enclosure with a rear cutout for access.

Core protection functions include thermal model-based overload, negative sequence imbalance, stall, mechanical lockup, ground overcurrent, short circuit, and differential protection, along with voltage-based features like overvoltage, undervoltage, and frequency monitoring. It also supports 12 RTD inputs for temperature tracking, 40-event recording with 16-cycle waveform capture per trip, and power measurement capabilities. Configuration is done via the EnerVista 469 installation software, which enables setting adjustments and system data export for analysis. The relay uses a draw-out design for easy maintenance and testing.
