FAQs
Installers should plan for Ethernet-based communication wiring to support IEC 61850 and Modbus/TCP. Ensure proper grounding, confirm space for 8 DI, 5 DO, and 4 AO I/O, and verify compatibility with existing control platforms. The unit’s URTD, IRIG-B, and Sensitive Ground Input options require correct connector configuration and protective enclosure suitable for industrial environments.
The EMR-4000-2A1HA0 natively supports IEC 61850 over RJ-45 and Modbus/TCP, enabling seamless integration with modern substation and plant networks. This interoperability reduces custom interface work, accelerates commissioning, and improves cross-vendor data exchange for protection, metering, and control tasks.
Yes. With zone selective interlocking (1) and built-in sensing for current, power, and voltage protection, the relay enables coordinated, selective tripping that minimizes impact on healthy sections. When paired with robust enclosure and proper IP-rated installation, it supports reliable operation in demanding industrial settings.
Compliance status is listed as 'Contact Manufacturer' in the data. In practice, verify IEC 61850 compatibility for communications, and confirm any CE, SIL, or IP-related certifications with Eaton for your specific installation. Also review warranty coverage and service documentation to align with your procurement and maintenance requirements.
The integrated protection, metering, and versatile I/O reduce panel wiring and external devices, cutting installation time and material costs. Ethernet-based communication simplifies diagnostics and upgrades, lowering maintenance labor and downtime. Over time, this translates to higher equipment reliability, faster fault isolation, and improved energy efficiency in motor-driven lines.
