Quick Summary

The Eaton EMR-4000-2A1DA0 motor relay is a compact control unit that provides integrated protection and motor monitoring for industrial drives in demanding environments. Engineers often face the challenge of aligning multiple protection layers across varied voltages and communications protocols within a single panel. Certification and compliance details vary by region; typical expectations include CE marking, IP enclosure protection, and SIL-capable safety features, with exact status verified by the manufacturer. By unifying sensing inputs, current and voltage protection, and fiber-optic communications, this relay streamlines panel design, reduces wiring complexity, and accelerates commissioning. In addition to core protection, its flexible I/O and compatibility with Eaton's PowerPort-E ecosystem support shorter downtime and improved site reliability for power protection and metering applications.

FAQs

Plan for a compact footprint: 8.06 in length, 9.72 in width, and 8.70 in height with a weight around 9.26 lb. Ensure panel space supports fiber-optic PROFIBUS-DP connectivity and URTD/IRIG‑B interfaces. Confirm supply compatibility across 19–300 VDC and 40–250 VAC and mount using compatible Eaton/mounting hardware for robust protection.
Key specs include 5A and 1A phase currents, 8 digital inputs, 5 digital outputs, 4 analog outputs, and 0 analog inputs. It supports 19–300 VDC and 40–250 VAC, plus I/O options like Sensitive Ground Input, IRIG-B, and URTD Interface. The device is a motor relay designed for motor protection and monitoring within Eaton's ecosystem.
Yes. The EMR-4000-2A1DA0 includes zone selective interlocking capability (1) and supports timing- and isolation-critical communications over fiber-optic networks, which assists in coordinated protection strategies. This makes it well-suited for complex motor protection schemes in automated facilities.
