Eaton EMR-4000-2A0FB0 Motor Relay - Conformal Coated PCB

Conformal coated circuitry provides resistance to moisture, dust, and corrosive environments, which translates to lower maintenance costs and longer service life in outdoor substations and rugged plant floors. This feature directly impacts total cost of ownership by reducing field failures and minimizing downtime during harsh conditions. The embedded fiber optic Modbus/DNP3 RTU communication enables reliable, interference-free data exchange with SCADA systems, enhancing remote monitoring, fault visibility, and interoperability across Eaton E-Series networks. In practice, this means faster fault localization and streamlined maintenance planning in large industrial facilities where cable runs are long and EMI is a concern. With 8 digital inputs, 5 digital outputs, and 4 analog outputs, the unit consolidates control and signaling in a single housing, reducing panel complexity and installation time while enabling precise motor control and status reporting for energy management. The device’s current, power, and voltage protection/meters deliver real-time protection data, enabling proactive shutdowns and safer operation, which lowers outage costs and supports compliance-driven maintenance. Zone selective interlocking (1) accelerates fault clearing and minimizes collateral damage in feeder protection schemes, improving overall plant reliability and electrical safety. The URTD Interface IRIG-B option provides time synchronization critical for coordinated protection schemes and accurate event logging, enhancing forensic analysis after faults. The wide operating range of 19-300 VDC and 40-250 VAC further supports field versatility across diverse motor applications, from small servo drives to larger motor nets. A 1-year Eaton warranty coupled with robust conformity to industry practices adds business value by reducing risk and ensuring support through the product lifecycle.
