Eaton EMR-3000-2B0FB0 Motor Relay - IRIG-B & Modbus RTU
Part Number: EMR-3000-2B0FB0
Quick Summary
Eaton EMR-3000-2B0FB0 motor relay is a programmable protective device for motor control and protection in industrial automation. Operators often struggle with unreliable remote signaling and timing during equipment startups, which can trigger unnecessary shutdowns. Compliance details are listed as 'Contact Manufacturer'—verify CE, IP ratings, and SIL certifications directly with Eaton for your region. With fiber optic communication, IRIG-B timing, and support for Modbus RTU or DNP3 RTU, the EMR-3000-2B0FB0 enables safer, more predictable operation. It offers 4 digital inputs and 4 digital outputs, current sensing with metering, and zone selective interlocking, all in a standard mounting footprint. This combination supports faster commissioning, easier troubleshooting, and improved lifecycle economics for new installations and retrofits.

FAQs
Install on a standard panel footprint with the device's 8.06 in depth and 8.62 in height in mind for enclosure clearance. Plan for fiber optic ST routing and IRIG-B wiring, ensuring proper shielded cabling for the Modbus RTU or DNP3 RTU over fiber interfaces. Align 4I/4O wiring with your control logic and safety interlocks to maximize protection reliability.
The EMR-3000-2B0FB0 operates at 50/60 Hz and supports 5A or 1A phase current. It provides 4 digital inputs and 4 digital outputs, with no analog I/O. The unit includes IRIG-B timing and an URTD interface, plus fiber optic Modbus RTU or DNP3 RTU communications for robust remote monitoring.
Yes. The relay supports Zone Selective Interlocking (ZSI) with a ZSI setting of 1, enabling selective tripping and faster fault isolation. This feature reduces system-wide outages and improves coordination between protection devices in motor control centers and switchgear configurations.
Compliance details are listed as 'Contact Manufacturer' in the product data. For regulatory approvals, verify CE, IP ratings, and SIL certifications directly with Eaton in your region. This ensures the device meets local electrical safety, environmental, and safety performance requirements for your application.
Benefits include improved uptime from reliable signaling and precise timing, reduced field wiring through centralized I/O, and energy monitoring via current protection and metering. The one-year warranty (or 18 months from shipment) supports lower total cost of ownership, while fiber communications enable remote diagnostics and faster issue resolution.
