Feature: 16 digital inputs and 9 digital outputs provide flexible I/O for motor protection strategies. Business impact: reduces the need for external controllers, minimizes wiring complexity, and lowers panel footprint, translating into faster commissioning and ongoing maintenance savings. Application: ideal for conveyors, hoists, fans, pump stations, and other motor-driven equipment where local logic and remote signaling are essential. Feature: Modbus RTU or DNP3 RTU over RS-485 communications adds open, standards-based networking. Business impact: seamless integration with existing SCADA and DCS architectures, enhanced fault visibility, and easier data collection for predictive maintenance. Application: suitable for manufacturing lines, water/wastewater facilities, and process automation where remote monitoring is required. Feature: Comprehensive sensing inputs including voltage protection and metering, current protection and metering, power protection and metering, and differential protection. Business impact: precise protection settings guard motors against overcurrents, voltage sags, and power quality events, lowering downtime and extending motor life. Application: critical in high-duty-cycle drives, centrifuges, pumps, and grinding mills where protection accuracy matters. Feature: Projection mounting and removable terminals enable quick, tool-friendly wiring and servicing. Business impact: faster field wiring, easier terminal replacement, and reduced risk during upgrades or expansions. Application: panel builders and OEMs deploying in cramped switchgear, control rooms, or modular enclosures where serviceability matters. Feature: Zone selective interlocking with a single-zone setting enhances selectivity during faults. Business impact: reduces mechanical wear on breakers, minimizes unnecessary trips, and improves system availability. Application: medium to large motor assemblies in plants with shared feeders, such as packaging lines or large centrifugal pumps, where coordinated protection pays for itself over time.

FAQs

Begin by powering the unit from 19–300 Vdc or 40–250 Vac as specified, then connect field wiring to the removable terminals for straightforward wiring. Mount the device via projection mounting in the panel and wire the 16 digital inputs and 9 digital outputs according to your protection scheme. Finally, configure Modbus RTU over RS485 or DNP3 RTU to integrate with your SCADA system and verify zone selective interlocking settings for selective protection.
The relay offers voltage protection and metering, current protection and metering, power protection and metering, and differential protection sensing inputs. This combination enables precise protection against overcurrents, voltage excursions, and power quality events, reducing motor wear and unplanned downtime while supporting detailed fault analysis.
Yes. With 16 digital inputs, 9 digital outputs, 5A/1A current sensing, RS485 communication, and zone selective interlocking, the EMR-5000-2A0BB1 is well-suited for conveyors, pumps, fans, and other motor-driven equipment where robust protection and reliable remote monitoring are essential.
Compliances are listed as 'Contact Manufacturer' for regional specifics. In practice, verify CE marking, IP enclosure rating, and SIL capabilities with Eaton for your target market. Always confirm regional regulatory requirements before deployment to ensure full compliance in your facility.
By consolidating protection logic, I/O, and communications in one device, the relay reduces wiring and panel space, speeds commissioning, and improves fault visibility. These factors translate to lower maintenance costs, reduced downtime, and faster return on investment through improved motor uptime and streamlined integration with SCADA/MES systems.
