Eaton EMR-3000-2B1IA1 Motor Relay - IRIG-B URTD Interface
Part Number: EMR-3000-2B1IA1
Quick Summary
Eaton EMR-3000-2B1IA1 motor relay provides integrated control for industrial motors in harsh environments. In many facilities, start-up sequencing and protective interlocks are costly and error-prone, making reliable motor control a priority. Compliance expectations vary by region; verify with the manufacturer, while leveraging URTD Interface, IRIG-B timing, Modbus RTU over RS-485 and Modbus TCP over Ethernet to simplify integration. This motor relay supports 5A/1A phase current protection, a wide supply range of 19–300V DC and 40–250V AC at 50/60 Hz, and flexible I/O for remote sensing and metering. Together, these features reduce downtime, improve safety, and enable scalable monitoring across distributed motor networks.

Eaton Specification Sheet - EMR-3000-2B1IA1
Wide supply and current capabilities enable universal installation across motor fleets. The EMR-3000-2B1IA1 accepts 19–300V DC and 40–250V AC at 50/60 Hz, supporting both new builds and retrofits without a voltage mismatch. This translates into lower spare-part inventories and faster commissioning on the factory floor, a tangible efficiency gain for procurement teams and maintenance engineers alike. Integrated motor protection and metering deliver measurable reliability. With 5A and 1A phase current ratings, combined with current protection and metering, you can detect overloads early and avoid costly motor damage. This is particularly valuable in conveyors or pumps where uptime directly affects throughput and energy costs. Flexible I/O and zone selective interlocking simplify control logic. Four digital inputs and four digital outputs give you direct interface to PLCs and smarter interlocks, reducing wiring and potential misconfigurations. The included URTD Interface and IRIG-B timing support precise synchronization and robust diagnostics in distributed automation networks. Robu st communications enable remote monitoring and centralized control. RS-485 Modbus RTU and Ethernet TCP/IP allow you to collect operational data and issue commands without onsite visits. This reduces maintenance visits and accelerates troubleshooting across multi-site installations. Warranty and installation flexibility reduce lifecycle risk. Eaton's policy offers a one-year warranty from install or eighteen months from shipment, easing procurement risk. The compact, projection-mount design and universal mounting footprint streamline panel integration and retrofits.

FAQs
The EMR-3000-2B1IA1 uses a projection mounting method and provides four digital inputs and four digital outputs for direct PLC interfacing. It supports Modbus RTU over RS-485 and Modbus TCP over Ethernet, allowing straightforward integration with existing control networks. The wide voltage range (19–300V DC and 40–250V AC) and 50/60 Hz operation facilitate both new installations and retrofits without additional power conditioning, reducing installation time and wiring complexity.
This motor relay is rated for 5A and 1A phase current, with a broad operating voltage range of 19–300V DC and 40–250V AC. It operates at standard industrial frequencies of 50/60 Hz. These specs support versatile motor protection and metering across varied motor sizes and system voltages, enabling consistent performance in mixed-vendor environments.
Yes. The EMR-3000-2B1IA1 is designed for motor control and protection in diverse applications such as conveyors, pumps, and industrial fans. Its zone selective interlocking (ZSI) capability, four digital I/O, and robust communications enable coordinated start/stop sequencing, selective tripping, and remote monitoring—key for high-uptime material handling and process automation environments.
Compliance details for this model are listed as 'Contact Manufacturer.' For project-specific certification needs (CE, UL, IP ratings, SIL), confirm with Eaton or an authorized distributor to ensure the configuration meets regional and industry regulatory requirements and installation standards.
The EMR-3000-2B1IA1 is covered by Eaton's warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. This warranty, combined with remote monitoring capabilities over RS-485 and Ethernet, supports faster fault diagnosis, reduced maintenance travel, and a lower total cost of ownership for motor control in multi-site operations.
