Eaton Specification Sheet - EMR-3000-2B0DA1
Four digital inputs and four digital outputs are bundled in a compact module, reducing cabinet wiring, speeding commissioning, and enabling precise sequencing in motor control panels for conveyors and packaging lines. IRIG-B URTD timing interfaces provide accurate synchronization for distributed automation, improving fault analysis and interlock strategies in data centers and large manufacturing cells. PROFIBUS-DP over fiber optic ST delivers robust fieldbus communications with EMI immunity and long-distance reliability, ideal for remote motor banks in harsh environments. Zone Selective Interlocking (ZSI) enables selective tripping, minimizing downtime and energy loss during fault conditions in multi-motor drives. Current protection and metering sensing inputs enable real-time protection and power monitoring, supporting energy efficiency programs and compliant reporting. Projection mounting and the compact footprint simplify installation in tight control cabinets, while compatible Eaton E-Series relays streamline maintenance and spare-part planning. The combination of these features supports faster commissioning, reduced wiring errors, and improved overall system reliability in industrial automation settings.
