Quick Summary

Eaton motor relay EMR-3000-2B0KB0 provides reliable motor control for industrial automation and process equipment. Many projects struggle with integrating multiple I/O schemes and protecting motors without sacrificing uptime; this device consolidates protection, metering, and fiber-optic networking in a single package to streamline deployment. While the data sheet lists general compliance details, verify certification specifics with Eaton to ensure site-appropriate approvals; the unit supports 50/60 Hz operation, wide DC/AC voltage ranges, and conformal-coated boards for harsh environments. Designed for scalable control architectures, it aligns with modern Ethernet-based field networks and time-synchronization needs, helping reduce integration risk and accelerate project timelines.

Feature → Business Impact → Application: Four digital inputs and four digital outputs deliver flexible, compact control without adding external I/O hardware, reducing panel space and wiring complexity while enabling precise motor sequencing in packaging and material handling lines. This translates into faster commissioning and lower wiring costs on both new builds and retrofit projects. Feature → Business Impact → Application: Current protection and metering provide real-time visibility and fault isolation, improving motor reliability and enabling proactive maintenance strategies in continuous-process environments such as water treatment or chemical processing. Feature → Business Impact → Application: IEC 61850 over LC duplex fiber optic Ethernet enables seamless integration with substation and plant-wide networks, supporting scalable, standards-based architectures and easier remote diagnostics. Feature → Business Impact → Application: URTD Interface and IRIG-B time synchronization simplify event logging and coordinated protection schemes in multi-rack or multi-site installations, enhancing safety and operational coordination. Feature → Business Impact → Application: Conformal coated circuit boards improve reliability in humid, dusty, or humid environments common to manufacturing floors and outdoor enclosures, reducing failure rates and maintenance cycles. Feature → Business Impact → Application: Wide operating ranges of 19–300 VDC and 40–250 VAC plus 50/60 Hz compatibility ensure compatibility with existing power systems and drive equipment, minimizing rework and enabling smoother asset migrations. Industry-specific note: these capabilities support zone selective interlocking, precise motor protection, and networked control in automotive, food & beverage, and heavy industry environments where uptime matters.

FAQs

Start by matching the device network interfaces to your controller (IEC 61850 over LC fiber, Modbus/DNP3 TCP). Confirm that your PLC or SCADA supports fiber Ethernet protocols and that IRIG-B time synchronization requirements are met. Check wiring diagrams for the 4/4 I/O layout and ensure fanless, conformal-coated boards are suitable for the enclosure environment.
The EMR-3000-2B0KB0 supports 19–300 VDC and 40–250 VAC with a 50/60 Hz frequency rating. It provides 5 A and 1 A phase current protection options and includes current protection and metering. Plan for standard mounting and verify that your supply rails fall within these ranges to avoid performance limitations.
Yes. The unit features zone selective interlocking and URTD Interface with IRIG-B time synchronization, enabling coordinated protection and precise time-stamped events. This makes it appropriate for applications requiring synchronized protection across multiple devices, such as large motor drives in manufacturing lines or substations.
The data sheet lists ‘Compliances: Contact Manufacturer,’ so verify the exact certifications with Eaton for your region (examples often include CE, UL, and RoHS for electrical equipment). If your project mandates specific approvals, request the current certificate package and a formal declaration of conformity before purchase.
The integrated protection, metering, and fiber networking reduce wiring, simplify commissioning, and streamline diagnostics. Expect lower field maintenance costs due to conformal coating and durable hardware, faster fault isolation with time-synced events, and reduced downtime from a single, standards-based motor relay that supports scalable control architectures.
