Eaton Specification Sheet - EMR-3000-2A0BB0
RS-485 Modbus communication and IRIG-B URTD timing interfaces enable synchronized control across multi-panel systems, reducing wiring complexity and ensuring consistent data across drives. This translates to shorter commissioning times and improved fleet-wide uptime for automation applications in manufacturing and process industries. The EMR-3000-2A0BB0 provides 5A/1A current sensing with built-in current protection and metering, supporting real-time monitoring and energy management while helping prevent motor fault propagation into the broader plant network. Conformal-coated circuit boards improve reliability in humid, dusty, or chemically challenging environments, lowering service calls and extending service life in machine rooms and outdoor enclosures. The broad input range of 19–300 VDC and 40–250 VAC enables flexible power sourcing, simplifying panel design and reducing stock variety. With 4 digital inputs, 4 digital outputs, and 1 analog output, this relay supports complex logic and local sequencing, cutting external I/O wiring and simplifying panel layouts. The standard mounting method accelerates retrofits and new installations, minimizing support structure changes and enabling faster starts. A one-year warranty (or 18 months from shipment) reduces overall risk and protects capital investment, enhancing total cost of ownership for automation projects.

FAQs
EMR-3000-2A0BB0 offers Modbus RTU over RS-485 support and four digital inputs plus four outputs, enabling straightforward integration with existing PLCs and HMIs. The IRIG-B URTD interface provides accurate time synchronization for coordinated motor control across panels, reducing mis-timing issues and enabling reliable automation sequences.
The device supports 5A and 1A sensing with current protection and metering, and operates over 19–300 VDC or 40–250 VAC at 50/60 Hz. Conformal coating enhances reliability in harsh environments, and the unit’s 4 DI / 4 DO / 1 AO configuration supports local protection logic and fault isolation within motor control schemes.
Yes. With standard mounting, a compact footprint (8.06 in L x 8.62 in H x 6.82 in W) and a weight of 5.82 lb, it fits typical control cabinets. The built-in current protection, 4 DI/4 DO I/O, and IRIG-B timing bolster reliability, reduce wiring, and streamline retrofits in factory automation and process industries.
Compliances are defined by the manufacturer; the data indicates to verify with Eaton for region-specific certifications. In many industrial deployments, motor relays of this class pursue CE and UL listings, and IP-rated housings are common for harsh environments. Always confirm current certifications with the supplier and document the exact regional requirements during procurement.
The relay’s conformal coating, current protection, and integrated IO reduce field maintenance by lowering fault incidence and simplifying wiring. Its time synchronization, modular IO, and standard mounting shorten installation times, while the 1-year (or 18-month) warranty lowers initial risk. Overall, expect reduced downtime and lower total cost of ownership in automated motor control applications.
