GE FANUC SR469-P5-HI-A20 Multilin Motor Management Relay
Description
The GE FANUC SR469-P5-HI-A20 Multilin Motor Management Relay is part of the 469 series of motor management relays, designed for comprehensive motor protection and monitoring in industrial applications including aluminum production, automotive, aerospace, and metallurgy. Key technical specifications include four 4-20mA analog outputs, a flexible control power range of 90-300VDC and 70-265VAC, 48-62Hz, and 1A phase CT secondary phase current input. An optional DeviceNet communication module is available, which provides three connection ports with 5-pin Phoenix connectors, supports baud rates of 125K, 250K, or 500K, and adheres to the DeviceNet protocol. For enhanced connectivity, the variant model SR469-P5-HI-A20-T adds an integrated Ethernet port on the rear, requiring a specialized SR469 enclosure with a rear cutout for access, and is configured via the EnerVista 469 software, which can be used to set parameters and export system data. Core protection features include thermal model-based overload protection, stall, mechanical lockup, ground overcurrent, short circuit, and differential protection, plus support for 12 RTD inputs and voltage transformer inputs for over/undervoltage, phase reversal, and over/underfrequency monitoring. It also offers power measurement functions, event logging for up to 40 recent events with 16 cycles of waveform data per trip, and a user interface with a vacuum fluorescent display, keypad, RS232, and dual RS485 ports. The draw-out design simplifies testing, maintenance, and component replacement.
