Eaton EMR-4000-2A1FA1 Motor Relay - URTD Interface
Part Number: EMR-4000-2A1FA1
Quick Summary
Eaton motor relay EMR-4000-2A1FA1 delivers integrated motor protection and control for demanding industrial applications. Operators often struggle to deploy reliable protection that remains compatible with existing fiber networks and metering capabilities. Certification expectations typically include CE, IP ratings, and SIL compatibility; consult Eaton for exact status on this model. By combining extensive I/O with fiber-optic Modbus RTU and URTD, this relay supports scalable, compliant control and real-time diagnostics. This translates to reduced downtime, improved energy management, and a clearer path to regulatory compliance for plant-wide motor control.
