Eaton Specification Sheet - EMR-5000-2A1DA0
Feature → Business Impact → Application: The EMR-5000-2A1DA0 integrates motor protection with networked control, reducing unplanned downtime and extending motor life in demanding applications such as conveyors and pumps. This consolidation simplifies panel design and maintenance, delivering faster troubleshooting and lower total cost of ownership for OEMs and end users. Application-wise, the unit’s robust digital I/O (16 DI, 9 DO) supports complex interlocking schemes and zone selective interlocking, ensuring selective tripping and reduced collateral outages across critical motor circuits.Feature → Business Impact → Application: Profibus-DP over fiber optic ST provides noise-immune, high-reliability communication between the relay and PLCs, enabling accurate monitoring and fast fault isolation. In practice, this translates to improved data integrity, easier remote diagnostics, and smoother integration into existing automation architectures in food & beverage, packaging, and material handling lines.Feature → Business Impact → Application: The device supports a wide voltage range (19-300 Vdc, 40-250 Vac) and 50/60 Hz operation, giving design teams flexibility to protect motors across multi-voltage plants without multiple relay inventories. This reduces spare parts and speeds up commissioning in mixed-volt environments such as mixed-plant production lines and retrofits.Feature → Business Impact → Application: Semi-flush mounting with removable terminals and a base relay option (EMR-4000) simplifies installation and field maintenance. Technicians benefit from quick connections and straightforward swaps, shortening downtime during maintenance windows in industrial facilities and upgrade projects.Feature → Business Impact → Application: The sensing inputs cover voltage protection and metering, current protection, and power protection, providing comprehensive motor health data. This capability supports predictive maintenance programs, aligns with energy-management initiatives, and helps ensure compliant operation in regulated industries like chemical processing and mining.

FAQs
The EMR-5000-2A1DA0 is designed to mount with the EMR-4000 base. Begin by removing the base for terminal access, connect the 16 digital inputs and 9 digital outputs to your control circuit, and ensure the removable terminals are properly secured. After mounting, wiring should follow the 50/60 Hz system standards and ensure Profibus-DP fiber optic communication is correctly terminated to maintain data integrity.
This model provides removable terminals for easy field service. It includes 16 digital inputs and 9 digital outputs, with 0 analog inputs and 0 analog outputs. Communication is via Profibus-DP over fiber optic ST, and the sensing inputs cover voltage protection, current protection, and power protection. Ensure correct voltage range (19-300 Vdc, 40-250 Vac) and secure fiber optic connections for reliable operation.
Ideal for industrial drive systems requiring integrated motor protection and fieldbus control. Its zone selective interlocking (1) supports selective tripping, reducing collateral outages. It suits packaging lines, conveyors, pumps, and other motors where 16 DI and 9 DO enable complex interlocks, while Profibus-DP provides robust PLC communication for centralized monitoring.
Compliances are listed as Contact Manufacturer, so verify CE, SIL, IP ratings, and regional regulatory requirements directly with Eaton. If your project mandates specific certifications, obtain official documentation from Eaton to ensure the device meets your safety, reliability, and environmental standards before procurement.
By combining protection, control, and fieldbus communication in a single device, downtime is reduced through faster fault isolation and easier diagnostics. The removable terminals and base-relay compatibility streamline maintenance and replacement, lowering labor costs and spare-part proliferation while supporting predictive maintenance initiatives for motor-heavy facilities.
