Eaton Specification Sheet - EMR-3000-2A1BA0
Feature → Business Impact → Application: Conformal coating on circuit boards protects against moisture and contaminants, extending product life in dusty or humid environments, reducing maintenance costs and unexpected downtime in continuous-process facilities. This supports longer intervals between service windows and improves equipment availability in heavy industry settings. Feature → Business Impact → Application: LC duplex fiber Ethernet for Modbus/DNP3 TCP communications delivers noise-immune, high-bandwidth data transmission across plant networks, enabling reliable remote monitoring and control from central HMI/SCADA systems. This is ideal for distributed automation across multi-room facilities or remote sites. Feature → Business Impact → Application: IRIG-B URTD Interface provides precise timing and synchronization for coordinated motor control and data logging, improving cycle accuracy and traceability in batch or synchronized production lines. Application includes packaging, metals, and chemical processing where timing coherence matters. Feature → Business Impact → Application: 5A/1A phase current capability and integrated current protection and metering enable accurate load monitoring and protective interlock decisions, reducing energy waste and preventing motor damage in high-demand drives. Perfect for line start/stop routines and energy-efficient motor management. Feature → Business Impact → Application: Modbus/DNP3 TCP over fiber Ethernet simplifies network architecture by consolidating control and telemetry on a single fiber backbone, reducing wiring complexity and installation time in large-scale automation projects. Useful for automotive, food & beverage, and oil & gas facilities requiring modular, scalable controls. Feature → Business Impact → Application: Projection mounting and compact footprint (8.06 in x 8.62 in x 6.82 in; ~5.82 lb) allow straightforward panel integration, minimizing enclosure changes and enabling flexible placement across retrofit and new-build projects. This suits OEMs and integrators delivering turnkey motor-control solutions.

FAQs
Begin with proper mounting using the projection method, then wire the four digital inputs and four outputs, plus the one analog output as specified. Power the unit from 19-300 VDC or 40-250 VAC, and configure Modbus or DNP3 TCP over the LC duplex fiber Ethernet. Integrate IRIG-B URTD as required for timing. Confirm protection schemes using current protection and metering features to monitor load conditions.
The device supports 5A/1A phase current, 50/60 Hz operation, and a dedicated motor relay function with current protection and metering. Its conformal coating improves reliability in harsh environments, while fiber Ethernet enables robust, long-distance communication. Combined, these characteristics reduce downtime and enhance monitoring for motor-driven processes.
Yes. The EMR-3000-2A0LB1 is designed for Modbus/DNP3 TCP over LC duplex fiber Ethernet, enabling seamless integration into existing industrial networks and SCADA systems while maintaining low latency and high reliability across the control fabric.
Formal certifications such as CE, SIL, or IP ratings should be confirmed with Eaton for this specific model. The product includes conformal coating and industrial-grade construction, but buyers should request the manufacturer’s current certification documentation to ensure regulatory alignment with their application and region.
The EMR-3000-2A0LB1 delivers enhanced uptime through remote monitoring, current protection, and metering, reducing unexpected motor failures. The warranty offers one year from installation or 18 months from shipment, whichever comes first, supporting predictable maintenance costs. The fiber network and reduced wiring complexity further lower installation time and total cost of ownership.
