Eaton Specification Sheet - EMR-5000-2A1EB0
Removable terminals and a base EMR-4000 platform simplify installation and spare-part compatibility, reducing wiring errors and field downtime. Business impact: faster commissioning, lower maintenance costs, and improved panel reliability in motor control centers. Application: large-scale drive systems, conveyors, and packaging lines requiring quick wiring changes without hardware rework. Profibus-DP over D-Sub/RS-485 enables seamless integration into existing factory networks, reducing integration time and supporting centralized diagnostics. Business impact: material downtime reduction and improved fault tracing. Application: OEM automation cabinets and control rooms where networked protection is essential. Wide input ranges of 19-300 VDC and 40-250 VAC support both DC drives and AC motors, delivering flexible deployment across mixed fleets. Business impact: fewer part numbers and streamlined spares. Application: mixed-energy motor parks in manufacturing floors. Sensing inputs deliver differential, voltage, current, and metering protection, enabling precise coordination and metering for energy reporting. Business impact: improved protection selectivity and energy visibility. Application: electrical distribution to motors in process lines. Zone selective interlocking and 50/60 Hz operation support fast fault isolation and reliable function in high-speed protection schemes. Business impact: shorter outage times and enhanced safety. Application: power distribution panels for heavy machinery. Conformal coating and semi-flush mounting enhance durability in harsh environments, reducing corrosion risk and easing installation in tight spaces. Business impact: longer service life and simpler retrofits. Application: compact control panels in manufacturing cells. The 16 digital inputs and 9 digital outputs provide scalable I/O for local interlocking and status indication. Business impact: richer control logic without external gateways. Application: machine-side motor protection and panel-level supervision.

FAQs
EMR-5000-2A1EB0 uses semi-flush mounting with removable terminals, facilitating fast field wiring and straightforward panel integration. The removable terminals simplify maintenance and allow quick re-routing or replacement without full disassembly of the enclosure.
The relay supports Profibus-DP over D-Sub or RS-485, enabling direct integration with existing industrial networks. With 16 digital inputs and 9 digital outputs, it provides local I/O for interlocks and status signaling, reducing the need for external controllers.
Yes. The EMR-5000-2A1EB0 combines motor protection with multiple sensing modalities (differential, voltage, current, metering) and Zone Selective Interlocking, offering fast fault isolation and reliable operation in conveyor drives and other continuous-motion applications.
Compliance details require direct confirmation from the manufacturer. Typical considerations for Eaton motor protection relays include CE markings, IP considerations, and SIL-capable features within broader Eaton E-Series families; verify the exact certification status with Eaton for this model and your region.
Warranty is Eaton Selling Policy 25-000, covering one year from installation or eighteen months from shipment, whichever occurs first. Regular maintenance should focus on connector integrity, terminal cleanliness, and firmware/communication checks to sustain protection reliability.
