Eaton EMR-3000-2A1DA0 Motor Relay - IRIG-B/URTD
Part Number: EMR-3000-2A1DA0
Quick Summary
Eaton motor relay EMR-3000-2A1DA0 provides robust motor control for industrial automation. Engineers often struggle with reliable fieldbus integration, motor protection, and uptime across mixed voltage environments. In many markets CE marking, UL/CSA compliance, and IP-rating options are available to meet safety and environmental standards. This combination enables faster commissioning, reduced downtime, and lower lifecycle costs through integrated protection, monitoring, and flexible I/O. The EMR-3000-2A1DA0 supports a broad voltage range and fiber optic communication for rugged plants, helping teams standardize on a single relay platform. By aligning with Eaton’s warranty and service policy, maintenance planning becomes more predictable and procurement simpler.

FAQs
The EMR-3000-2A1DA0 is designed for standard motor relay panels with four digital inputs and four outputs plus one analog output. To install, mount on a standard DIN rail, wire digital I/O to the control PLC or PLC/HMI, connect the URTD or IRIG-B interfaces as required, and route the PROFIBUS-DP fiber optic link to the fieldbus master. Ensure supply voltage stays within the 19–300V DC and 40–250V AC range and verify ground reference with the Sensitive Ground Input for protection against stray currents.
This relay provides current protection and metering for motor circuits with ratings of 5A and 1A. The unit monitors real-time current to detect overload conditions and deliver accurate metering data to the control system. Use the metering data to trigger protective actions, improve energy management, and support fault analysis during post-event diagnostics.
Yes. The EMR-3000-2A1DA0 supports PROFIBUS-DP over a fiber optic ST interface, delivering high noise immunity and reliable communication in electrically noisy plant environments. This makes it suitable for distributed motor control architectures and remote automation nodes where robust fieldbus connectivity is critical for uptime and data integrity.
Compliances are provided by the manufacturer and vary by region. Typical certifications for motor relays in this class include CE marking and UL/CSA where applicable, with IP ratings available on request. For exact certification scope and regional compliance, consult Eaton’s specifications for EMR-3000-2A1DA0.
The EMR-3000-2A1DA0 carries Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever comes first. This reduces maintenance risk and simplifies budgeting. Combined with integrated protection, metering, and flexible I/O, the device can lower downtime, extend motor life, and streamline procurement—delivering measurable ROI through increased system availability.
