Eaton EMR-4000-2A0BB0 Motor Relay - IRIG-B Interface
Part Number: EMR-4000-2A0BB0
Quick Summary
Eaton motor relay EMR-4000-2A0BB0 provides robust motor protection and control for industrial drive systems. In harsh environments, operators need reliable protection, precise metering, and straightforward remote diagnostics. Engineers often wrestle with coordinating protection logic, communication, and protection coordination across multiple motors. Certification details vary by installation, but typical standards for motor relays include CE markings, IP-rated enclosures, and SIL readiness where required; consult the Eaton datasheet for exact compliance. This solution pairs RS-485 Modbus/DNP3 RTU, IRIG-B interface, and conformal coated circuitry to deliver visibility, resilient operation, and reduced downtime, all while enabling scalable monitoring and metering for power protection and current protection across the plant.

Eaton Specification Sheet - EMR-4000-2A0BB0
RS-485 Modbus/DNP3 RTU communications enable seamless integration with PLCs and SCADA systems, reducing wiring and commissioning time while enabling remote diagnostics. This translates to faster fault isolation and improved asset utilization in motor control panels and distributed drive architectures. IRIG-B time synchronization and URTD interface provide precise timing and data routing for coordinated protection across multiple devices, enhancing selectivity in complex automation lines and minimizing nuisance tripping. The device includes voltage protection and metering, current protection and metering, delivering actionable energy data and improved fault analytics to support maintenance planning and energy efficiency programs. Conformal coated circuit boards boost reliability in dusty or humid environments, reducing field failures and service calls while extending MTBF in outdoor or harsh factory settings. With 8 digital inputs, 5 digital outputs, and 4 analog outputs, plus 1 zone-selective interlocking (ZSIL) option, engineers gain flexible control topology for motor start/stop sequencing and safety interlocks. These capabilities align with compliance and retrofit projects, delivering measurable reductions in downtime, faster commissioning, and scalable monitoring across plant networks. Compatible with existing Eaton E-Series and third-party control ecosystems, the EMR-4000-2A0BB0 simplifies installation and future-proofing of motor protection strategies in automated facilities.

FAQs
Plan for RS-485 wiring with proper termination and shielding to support Modbus RTU and optional DNP3 RTU; ensure correct IO mapping to 8 digital inputs, 5 digital outputs, and 4 analog outputs. If time synchronization is needed, configure the IRIG-B URTD interface. Verify voltage range requirements of 19-300Vdc or 40-250Vac and accommodate conformal-coated boards for humidity or dust exposure in industrial panels.
Yes, EMR-4000-2A0BB0 supports Modbus RTU over RS-485. Data is accessed via a standard Modbus register map, enabling remote monitoring and control from PLCs or SCADA systems. Compatibility with DNP3 RTU provides flexible integration in modern substation and plant networks. For time-critical applications, IRIG-B time synchronization can be used in tandem with metering data for accurate event sequencing.
Yes, the motor relay employs conformal coated circuit boards to improve reliability in challenging environments with dust, humidity, or chemical exposure. This makes it well-suited for outdoor cabinets, damp plant spaces, or automotive/machine interiors where protection against corrosive or conductive contaminants is required, helping to extend service intervals and reduce field failures.
The EMR-4000-2A0BB0 delivers voltage protection, current protection, and power protection with integrated metering. It supports 5A and 1A phase currents and provides digital and analog I/O for sensing and control. This combination enables precise fault detection, event logging, and energy measurement, supporting maintenance planning, energy optimization, and compliance reporting in automated motor systems.
The device is covered by Eaton’s standard warranty policy: one year from installation or eighteen months from shipment, whichever comes first. Support includes access to Eaton documentation such as datasheets and application notes, plus access to technical support for integration questions, Modbus/RS-485 configuration, and protection metering setup.
