Eaton EMR-4000-2A0DB0 Motor Relay - Fiber Optic Interface
Part Number: EMR-4000-2A0DB0
Quick Summary
Eaton motor relay EMR-4000-2A0DB0 provides reliable motor protection and control for industrial drives in automated manufacturing and process lines. This device helps engineers reduce wiring complexity while delivering integrated protection, metering, and remote signaling. For many users, the challenge is protecting motors from overcurrent and voltage transients while maintaining visibility across control networks; this relay addresses that with configurable sensing inputs and metering capabilities. While compliance specifics vary by region, key industry certifications such as CE, SIL, and IP-related ratings are typically relevant for this class of equipment; always confirm with the manufacturer. By combining conformal coated circuit boards, fiber optic communication, and broad I/O, it enables faster commissioning and lower total cost of ownership.
