Feature → Business Impact → Application: Modbus RTU or DNP3 RTU over D-SUB / RS-485 enables seamless PLC/SCADA integration, reducing wiring errors and enabling remote diagnostics. This translates to faster commissioning, improved asset visibility, and reduced field service time in motor-control panels across packaging, food & beverage, and water treatment facilities. Feature → Business Impact → Application: 16 digital inputs and 9 digital outputs with removable terminals support richer motor condition monitoring and control sequences, accelerating fault isolation and maintenance planning in conveyors, pumps, and fans. Feature → Business Impact → Application: IRIG-B URTD timing interface option and projection mounting simplify time-synchronised monitoring and panel installation in harsh industrial environments. Feature → Business Impact → Application: Wide voltage range (19–300 VDC / 40–250 VAC) and 50/60 Hz compatibility enable retrofits and new builds with minimal power conditioning, reducing upgrade costs and downtime. Feature → Business Impact → Application: Base-relay compatibility with EMR-4000 and zone selective interlocking (ZSI = 1) improve protection coordination across compartments, lowering the risk of cascading trips in large drives. Feature → Business Impact → Application: 8.06 in length, 8.7 in height, 9.72 in width and 9.259 lb weight provide a predictable panel footprint, easing integration and reducing enclosure rework in OEM assemblies and plant upgrades.

FAQs

Begin with mounting the unit in a standard control panel, connect the removable terminals for motor leads and field wiring, then wire the D-Sub RS-485 interface to the PLC or SCADA network. Configure Modbus RTU addressing, baud rate, and parity per the Eaton specification sheet. Use the 16 digital inputs and 9 outputs to integrate motor status signals and interlock logic for safe startups and fault isolation.
The EMR-5000-2A0GB1 combines a broad voltage range, 50/60 Hz compatibility, and removable terminals with robust communication options (Modbus RTU/DNP3 RTU over RS-485). This enables reliable protection, easier maintenance, and straightforward retrofits in conveyors, pumps, and fans, while supporting zone selective interlocking to limit fault propagation and downtime.
Yes, the EMR-5000-2A0GB1 is designed to work with the EMR-4000 base relay. Zone Selective Interlocking (ZSI) enhances coordination across protection zones, enabling faster fault isolation and reduced equipment damage in multi-drive installations. This compatibility simplifies upgrades and ensures consistent protection strategies plant-wide.
The relay accepts 19–300 VDC and 40–250 VAC with 50/60 Hz operation, and supports phase current options of 5A and 1A. Communications use Modbus RTU or DNP3 RTU over RS-485 with a D-Sub interface. For retrofits, verify existing control network compatibility, wire routing, and available I/O to match your motor protection and monitoring requirements.
Official documentation is available from Eaton, including the EMR-5000-2A0GB1 specification sheet and the Selling Policy 25-000 warranty guide.
