Eaton EMR-3000-2B0LB0 Motor Relay - IRIG-B

Fiber optic Ethernet connectivity with Modbus and DNP3 over LC duplex fiber provides robust, galvanically isolated communication between the relay and your control system. This reduces wiring complexity and improves data integrity, which translates into faster fault diagnosis and safer remote monitoring in harsh factory environments. The EMR-3000-2B0LB0 fits modern automation architectures where real-time status and programmable interlocks are essential.Current protection and metering give clear visibility into motor health and energy use. By detecting overload or abnormal current early, it prevents motor damage and unplanned downtime, while enabling energy reporting for maintenance and efficiency programs. This feature is especially valuable in continuous operation lines and high-duty cycles.Four digital inputs and four digital outputs offer flexible signaling for zone interlocking, start/stop control, and safety interlocks without additional racks. The built-in URTD interface and IRIG-B timing deliver precise synchronization with other devices in the drive train, improving coordination and reducing mis-timing events.Wide input ranges of 19-300 Vdc and 40-250 Vac support both DC and AC motor systems, allowing a single relay to cover a range of motor types and supply conditions. This versatility reduces spare parts, speeds retrofits, and simplifies procurement for plant-wide upgrades.Standard mounting and compact dimensions (8.06 in x 8.62 in x 6.82 in) with a modest 5.82 lb weight simplify panel installation and integration into existing enclosures. The combination of protection features, fiber communications, and industry-standard interfaces helps ensure long service life and predictable maintenance cycles.
