Eaton EMR-5000-2B0KA1 Motor Relay - IEC 61850 Fiber

Comprehensive protection and metering are built into the EMR-5000-2B0KA1 through sensing options that include Voltage Protection and Metering, Current Protection and Metering, Power Protection and Metering, and Differential Protection. This rich sensing enables precise fault detection and accurate energy measurement, improving selectivity and reducing motor damage during transient events. In practice, this level of protection supports motor protection relays for pumps, fans, and conveyors across manufacturing, water treatment, and process industries. Flexible I/O and interlocking: The relay provides 2 analog inputs, 2 analog outputs, 8 digital inputs, 9 digital outputs, plus Zone Selective Interlocking and an IRIG-B URTD interface. Business impact: expanded on-device logic lowers reliance on external controllers, speeds fault isolation, and simplifies time-stamped event recording for post‑event analysis. Application: complex protection schemes for multi-motor drives, packaging lines, and heavy equipment rooms where space and wiring are at a premium. Industrial networking and interoperability: It supports IEC 61850 over LC duplex fiber optic Ethernet and Modbus/DNP3 TCP communications. Business impact: standards-based integration reduces engineering time, enables seamless data sharing across substation and plant networks, and eliminates copper run constraints. Application: utility interfaces, steel mills, and petrochemical plants needing robust, cyber-secure protection networking. Ease of maintenance and retrofit: Removable terminals and compatibility with the EMR-4000 base relay enable field replacement without rewiring, shortening maintenance windows. Business impact: lower lifecycle costs through easier upgrades and faster commissioning, with consistent field replacement parts. Application: retrofits on aging motor protection fleets and new builds that require rapid, serviceable protection modules. Power range, mounting, and timing: The EMR-5000-2B0KA1 accepts 19-300 Vdc and 40-250 Vac at 50/60 Hz, with projection mounting and removable terminals for straightforward installation. Business impact: broad electrical compatibility supports mixed voltage environments and simpler panel design, while fiber-based timing and interop features improve coordination. Application: large industrial drives, renewable energy interfaces, and data-center motor protection where uptime matters.
