Eaton Motor Relay EMR-3000-2B1IB1 - 50/60 Hz RS-485
Part Number: EMR-3000-2B1IB1
Quick Summary
Eaton motor relay EMR-3000-2B1IB1 delivers robust motor control and protection for industrial drives in packaging, processing, and manufacturing lines. Engineers often wrestle with integrating control, protection, and remote monitoring across diverse hardware and protocols, leading to friction, downtime, and inconsistent diagnostics. Certification status varies by region; consult the manufacturer for CE, SIL, and IP rating specifics to ensure regulatory alignment in your installation. This solution provides RS-485 Modbus and Ethernet TCP/IP communications, current protection and metering, and IRIG-B input options, delivering reliability at the point of load and simplifying integration with existing control architectures. By combining these capabilities with Eaton's support and warranty, you gain predictable performance and a lower total cost of ownership.

Eaton Specification Sheet - EMR-3000-2B1IB1
Four digital inputs and four digital outputs enable direct motor control logic and immediate fault signaling at the device level. This reduces wiring complexity and shortens troubleshooting cycles, helping maintain uptime in mission-critical lines. Use this configuration in motor protection panels and local control cabinets where fast status reporting makes a difference in throughput and safety. RS-485 Modbus and Ethernet TCP/IP interfaces provide multi-protocol connectivity. This simplifies integration with existing SCADA, PLCs, and remote monitoring platforms, reducing engineering time and commissioning risk. Application versatility across distributed control networks supports scalable automation architectures and remote diagnostics, improving asset visibility and maintenance planning. Current protection and metering support accurate load monitoring and energy accounting; IRIG-B input and URTD interface provide time synchronization and rugged grounding. This improves protection coordination and data integrity for dense industrial environments. The wide voltage range of 19-300 VDC and 40-250 VAC, plus 50/60 Hz operation, broadens compatibility with legacy and modern drives, easing panel retrofits. Projection mounting simplifies installation in tight spaces, while zone selective interlocking (1) enables precise fault isolation. Conformal coated circuit boards enhance reliability in harsh environments, reducing field failures and service calls. The Eaton ecosystem, including PowerPort-E monitoring, offers cohesive monitoring and faster diagnostics, delivering lower total cost of ownership over the life of the system.

FAQs
Begin with verifying voltage compatibility (19-300 VDC or 40-250 VAC) and confirm mounting alignment using the Projection method. Wire the four digital I/O lines and connect RS-485 and Ethernet ports to the PLC/SCADA network. Use the conformally coated circuit boards for harsh environments and ensure proper grounding with the URTD interface and IRIG-B option as needed.
Key specs include 5 A and 1 A phase current ratings, 4 digital inputs, 4 digital outputs, 0 analog I/O, and support for RS-485 Modbus RTU plus Ethernet TCP/IP. Frequency rating is 50/60 Hz, with a broad supply range of 19-300 VDC and 40-250 VAC. These enable flexible integration with modern and legacy drives.
Yes. The unit supports zone selective interlocking with a dedicated interlock capability (1), enabling selective tripping and reduced system-wide disturbances in multi-motor configurations.
