Eaton EMR-3000-2B1CB1 Motor Relay - Modbus Ethernet

Modbus and DNP3 communications run over Ethernet RJ-45, enabling direct integration with SCADA and PLC systems while centralizing diagnostics. This reduces wiring complexity, shortens commissioning time, and improves fault visibility across motor control panels. Ideal for automated production lines, energy management systems, and process automation where real-time telemetry is essential. Four digital inputs and four digital outputs provide precise control signals for start/stop logic, interlock schemes, and status reporting. Coupled with standard Modbus connectivity, this IO configuration supports fast local decisions, minimizes wiring errors, and simplifies panel layouts in packaging, material handling, and metals processing. Sensing inputs include current protection and metering, enabling early fault detection and energy accounting for motor assets. The Zone Selective Interlocking capability reduces unintended shutdowns by preventing widespread tripping, while URTD Interface, IRIG-B timing, and Sensitive Ground Input strengthen protection and synchronization. Operating from 19-300 VDC and 40-250 VAC at 50/60 Hz covers most regional power conditions, and the projection mounting supports precise alignment in compact cabinets. Conformal-coated circuit boards resist moisture and contaminants, extending service life in harsh industrial environments. Compatibility with Eaton’s E-Series and other automation hardware streamlines procurement and maintenance, and the built-in warranty reduces risk for mission-critical applications. Clear documentation, including the Eaton specification sheet, accelerates commissioning and helps ensure regulatory alignment.
