Eaton EMR-3000-2A1DB1 Motor Relay - Fiber Optic ST
Part Number: EMR-3000-2A1DB1
Quick Summary
The Eaton EMR-3000-2A1DB1 motor relay centralizes motor control in industrial automation panels. Engineers often struggle to fit robust protection, real-time timing interfaces, and fiber-connected communication into compact enclosures. Certification details are provided by the manufacturer; typical industrial standards can include CE-like compliance and IP-rated protection, with SIL/UL options available via configuration. Designed for 50/60 Hz systems and wide voltage ranges, this device supports flexible motor control while reducing panel complexity and wiring. Its 4DI/4DO, 1AO, and current protection metering enable smarter diagnostics and faster fault isolation.

Eaton Specification Sheet - EMR-3000-2A1DB1
Broad voltage and frequency support enables compatibility across machines and environments, reducing design variety and spare parts inventory. Feature → Business Impact → Application: 19-300 Vdc / 40-250 Vac with 50/60 Hz operation ensures reliable motor control for pumps, conveyors, and fans; ideal for mixed-voltage panels in manufacturing lines. The device provides four digital inputs, four digital outputs, and one analog output, enabling compact, integrated control without adding separate I/O modules; this reduces wiring time and cabinet footprint in machine builds. Current protection and metering improve reliability by early fault detection and energy monitoring, cutting unplanned downtime and maintenance costs in critical production lines. The URTD Interface and IRIG-B timing support precise synchronization for multi-axis drives and test benches, while PROFIBUS-DP over fiber optic ST ensures robust fieldbus communications in harsh environments. Projection mounting and a tested, rugged form factor simplify installation, align with standard panel practices, and minimize commissioning time. The Eaton warranty (one year from installation or 18 months from shipment) adds a layer of long-term support for industrial deployments. Compatibility with 50/60 Hz systems and broad voltage ranges makes this relay a practical choice for retrofit projects and new builds alike, delivering measurable efficiency gains and streamlined maintenance planning.

FAQs
Projection mounting is designed to align the relay precisely within the panel cutouts, enabling secure seating and straightforward wiring. To install, align the device with the mounting plane, insert onto the projection guides, and tighten standard hardware screws. Ensure adequate clearance for the fiber interface and accessible IO connectors for service. Proper mounting reduces vibration-related wear and simplifies future maintenance.
The device supports 19-300 Vdc and 40-250 Vac with a 50/60 Hz frequency rating. Phase current is 5A and 1A, with 4 digital inputs, 4 digital outputs, and 1 analog output. It includes current protection and metering, and supports I/O options such as URTD and IRIG-B timing. These specs enable integration into mixed-voltage motor control circuits and provide basic monitoring for efficient operation.
Yes. The EMR-3000-2A1DB1 supports PROFIBUS-DP over fiber optic ST, which improves noise immunity and reliability in harsh industrial environments. This makes it well-suited for remote motor control applications, multi-drive architectures, and plants requiring sturdy fieldbus performance across long cable runs.
The relay includes URTD Interface and IRIG-B timing options, enabling precise grounding references and high-accuracy timing for synchronized multi-axis drives or test setups. These features support tight control loops, improved fault correlation, and better coordination with other timing-critical equipment in advanced automation systems.
Eaton provides a warranty under policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first.
