FAQs
Plan for fiber optic cabling with LC duplex connectors and ensure proper cable routing to minimize bend radius. The unit supports conformal coated circuitry for harsh environments, and mounting should consider heat dissipation given the module size (8.06 in depth, 8.7 in height, 9.72 in width). Verify voltage range and wiring of 8 DI, 5 DO, and 4 AO to match control logic and protection schemes.
The relay provides integrated current and voltage protection, metering, and zone selective interlocking, enabling faster fault isolation and reduced downtime. With 5A/1A phase current options and wide voltage compatibility (19-300 Vdc, 40-250 Vac), it supports diverse motor loads while simplifying protection schemes and enabling accurate energy monitoring.
Yes. The unit supports IEC 61850 over LC duplex fiber optic Ethernet and Modbus/DNP3 TCP over LC duplex fiber, enabling seamless integration with modern substation and plant networks while preserving isolation and high-speed communication.
Warranty details follow Eaton Selling Policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. For technical support and configuration guidance, consult Eaton documentation and partners, as field terms may vary by region and application.
