Eaton EMR-4000-2A1CB0 Motor Relay - Over Ethernet RJ-45

Feature: Modular motor relay with integrated protection and metering. Business Impact: Improves reliability and reduces unplanned downtime by providing real-time current, voltage, and power measurements. Application: Used on industrial motor drives and automation panels to monitor load health and prevent faults before they propagate. Feature: Ethernet RJ-45 connectivity for Modbus/DNP3 RTU. Business Impact: Simplifies integration with SCADA and MES systems, enabling remote diagnostics and centralized control. Application: Ideal for retrofit projects and new builds that require standard industrial networking. Feature: 8 digital inputs and 5 digital outputs with 4 analog outputs. Business Impact: Expands I/O capabilities without adding external modules, lowering wiring complexity and panel footprint. Application: Suitable for complex motor fault signaling, interlocks, and process sequencing. Feature: 8 sensing inputs including Current/Power/Voltage protection and metering. Business Impact: Enhances protection schemes and energy accounting across load profiles, supporting compliance reporting. Application: Critical in energy-intensive applications and regulated environments. Feature: I/O options like Sensitive Ground Input, IRIG-B, and URTD Interface. Business Impact: Improves timing accuracy and grounding safety for precision control and synchronization. Application: Useful in data centers, aerospace, and manufacturing where timing and ground integrity matter. Feature: Zone selective interlocking support. Business Impact: Reduces fault clearance times and improves selective tripping, protecting equipment and improving uptime. Application: Essential in switchgear and medium-voltage motor control centers. Industry context and compatibility: Designed for motor control with broad voltage ranges (19–300 Vdc and 40–250 Vac) and interoperable with standard control architectures, enabling a smoother migration path for existing Eaton E-Series ecosystems and compatible drives. Installation and maintenance considerations: Compact footprint with defined dimensions (8.06 in length, 8.7 in height, 9.72 in width) and a weight of 9.259 lb, facilitating mounting in standard enclosures and minimizing renegotiation of panel layouts. Long-term value: The combination of native metering, versatile I/O, and robust protection translates to measurable energy insight, reduced maintenance costs, and improved lifecycle economics for motor-driven processes.
