Eaton Specification Sheet - EMR-5000-2B0DA0
Communication capability is a core feature; PROFIBUS-DP over fiber optic ST provides EMI-resistant, high-integrity communication between the relay and control system. This translates to fewer spurious trips and faster diagnostics, especially in noisy plant environments. In practice, engineers can locate the relay away from mains cables while maintaining deterministic data exchange for protection and metering. Versatile I/O and sensing deliver powerful protection; eight digital inputs, nine digital outputs, and two analog inputs plus two analog outputs enable granular control and precise fault signaling. This combination supports current, voltage, differential, and power protection schemes, enabling accurate metering and protection without external signal adapters. In new installations or retrofits, fleets can consolidate protection logic in a single device, reducing panel footprint. Removable terminals simplify wiring, testing, and field service; compatibility with EMR-4000 provides a clear upgrade path rather than a full replacement. The semi-flush mounting option and standard 50/60 Hz operation make onboarding straightforward across plant architectures. I/O options include IRIG-B URTD interface for time synchronization and zone selective interlocking, enabling selective tripping and coordinated protection across feeders. This capability improves safety, reduces collateral damage, and supports fast fault isolation in large motor systems. Designed to support motor protection relays in demanding environments, the EMR-5000-2B0DA0 helps meet maintenance windows and uptime KPIs with reliable fiber connectivity and modular upgrades. On-site technicians appreciate the clear wiring, diagnostic access, and compatibility with existing EMR-4000 baselines, accelerating project delivery in industrial automation contexts.

FAQs
EMR-5000-2B0DA0 is designed to integrate with the EMR-4000 base, offering a clear upgrade path and similar form-factor. Removable terminals simplify field wiring, testing, and retrofits, while the 8/9 I/O count aligns with common protection schemes. When upgrading, verify connector compatibility and ensure that the new relay’s protection logic aligns with existing zone interlocking and metering configurations to minimize re-wiring.
The unit supports 19-300 Vdc and 40-250 Vac, with 50/60 Hz operation. It includes 2 analog inputs and 2 analog outputs, plus 8 digital inputs and 9 digital outputs, enabling comprehensive current, voltage, differential, and power protection, as well as metering. This combination enables precise protection diagnostics without external signal modules, reducing panel complexity.
Yes, it provides PROFIBUS-DP over fiber optic ST communication. Fiber improves EMI resilience and allows longer, more reliable runs between the relay and the control system in harsh industrial environments. This reduces communication faults, enhances deterministic messaging for protection logic, and simplifies plant-wide synchronization with other devices on the same network.
Plan for semi-flush mounting and removable terminals to simplify installation. The device supports standard 50/60 Hz mains and integrates with the EMR-4000 base, enabling a scalable protection strategy. Consider IRIG-B URTD interface options for time synchronization in large systems and ensure adequate enclosure protection, wiring routing, and EMI management around fiber-enabled communication paths.
Upfront, you gain faster commissioning due to fewer external modules and easier wiring with removable terminals. Long-term, you benefit from improved uptime through robust EMI-resistant fiber communication, faster fault diagnosis from integrated metering, and scalable protection via the EMR-4000 base. These factors typically translate to reduced maintenance costs and shorter downtime in high-demand motor applications.
