Eaton EMR-4000-2A1DB0 Motor Relay - over fiber optic ST
Part Number: EMR-4000-2A1DB0
Quick Summary
The Eaton EMR-4000-2A1DB0 motor relay enables precise motor control for industrial automation systems. Engineers face wiring complexity and reliability challenges when scaling across multiple drives, often leading to longer install times and higher fault rates. Compliance specifics vary by region and must be confirmed with the manufacturer; nonetheless, its rugged design—conformal coated circuit boards, voltage protection and metering, and zone-selective interlocking—supports safer, more reliable operation in harsh environments. For OEMs and service teams, these features translate into lower maintenance, faster commissioning, and greater system uptime, with compatible interfaces like IRIG-B and PROFIBUS-DP.

Eaton Specification Sheet - EMR-4000-2A1DB0
Dual-voltage support (19-300Vdc / 40-250Vac) provides universal drive compatibility, reducing SKU sprawl and simplifying spares management across multiple panels. This flexibility directly translates to lower inventory costs and faster project ramp-up as you deploy the same relay throughout a line or plant. The device’s IO footprint—eight digital inputs, five digital outputs, and four analog outputs—consolidates sensing, control, and metering into one rugged module, delivering simplified wiring, quicker fault isolation, and clearer diagnostics in machine centers and conveyors. Its sensing protections (Voltage, Power, and Current Protection and Metering) improve protection alignment with motor loads, reducing unexpected outages and maintenance costs. The IRIG-B URTD interface and fiber optic PROFIBUS-DP support improve EMI resilience and timing accuracy in noisy environments. Conformal coating and zone selective interlocking further boost reliability and safe operation in harsh industrial settings, helping OEMs meet stringent uptime targets.

FAQs
Installation uses the motor relay's PROFIBUS-DP over fiber optic ST connection, paired with IRIG-B interface where precise timing is required. Ensure power is within the 19-300Vdc/40-250Vac range and connect the eight digital inputs, five digital outputs, and four analog outputs to the control architecture. Proper enclosure and grounding practices are essential to maximize EMI protection and reliable operation.
The EMR-4000-2A1DB0 supports dual voltage ranges: 19-300Vdc and 40-250Vac. Phase current specs are 5A and 1A, enabling flexible motor protection and metering schemes. When designing, account for peak inrush and steady-state loads and align protection settings to your motor and drive characteristics.
Yes. The unit includes zone selective interlocking (ZSI) capability, allowing selective fault isolation and faster maintenance without impacting upstream devices. This is particularly beneficial in multi-motor drives and MCC architectures where downtime impacts production lines.
Warranty is Eaton’s policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. Compliances are listed as to be confirmed with the manufacturer, ensuring regional and application-specific regulatory alignment before deployment.
Conformal coated circuit boards, current and voltage protection/metering, and a robust fiber optic interface collectively reduce corrosion risk, EMI-related faults, and wiring complexity. In practice, this yields lower maintenance costs, longer mean time between failures, and improved uptime for continuous-process equipment and high-demand industrial environments.
