Eaton Specification Sheet - EMR-4000-2A0GB1
Feature → Business Impact → Application: The EMR-4000-2A0GB1 delivers motor control with a broad voltage range (19-300 Vdc; 40-250 Vac) and built-in protection metering, reducing external components and wiring while improving system safety. This translates to lower installation costs and quicker commissioning for pump stations and conveyors in manufacturing lines. Feature → Business Impact → Application: Eight digital inputs, five digital outputs, and four analog outputs provide rich I/O coverage in a single module, enabling tighter integration with PLCs and HMIs while decreasing panel space and wiring errors in packaging, bottling, and material handling. Feature → Business Impact → Application: RS-485 based Modbus/DNP3 RTU and URTD IRIG-B interface simplify data exchange and time synchronization across distributed control networks, reducing integration risk and enabling precise coordination in multi-axis machines and remote monitoring. Feature → Business Impact → Application: Conformal coating and rugged construction improve reliability in dusty, humid, or temperature-variant environments, lowering maintenance cycles and extending mean time between failures on mining conveyors, ventilation systems, and process lines. Feature → Business Impact → Application: Sensing inputs for current, voltage, and power protection/meters, plus Zone Selective Interlocking, deliver targeted protection coordination, cutting energy waste and enabling faster fault isolation in large switchgear assemblies and OEM motor drives. Feature → Business Impact → Application: The compact footprint, warranty alignment (one year or 18 months from shipment), and Eaton support ecosystem provide predictable total cost of ownership and faster ROI for industrial automation projects.

FAQs
When replacing legacy relays, verify DIN rail or panel mounting compatibility, ensure wiring matches the EMR-4000-2A0GB1’s 8 digital inputs, 5 digital outputs, and 4 analog outputs, and confirm supply compatibility (19-300 Vdc / 40-250 Vac). Check the conformal coating suitability for the target environment and follow manufacturer installation guidelines to avoid signal interference and mis-wiring.
Key specs include 5A/1A phase current ratings, a broad voltage range (19-300 Vdc, 40-250 Vac), 8 digital inputs, 5 digital outputs, 4 analog outputs, and RS-485 Modbus/DNP3 RTU communication. The device also provides current, voltage, and power protection/meters, enabling integrated protection schemes and precise fault detection in automation loops.
Yes, the EMR-4000-2A0GB1 supports IRIG-B timing over the URTD interface. This enables precise time synchronization across multi-device control networks, improving coordinated motor control, event sequencing, and aligned data logging in complex production lines and remote monitoring architectures.
Best suited for industrial motor control in conveyors, pumps, packaging, and OEM equipment where integrated protection, metering, and communication are essential. Its 19-300 Vdc / 40-250 Vac capability, robust I/O, and IRIG-B timing make it ideal for environments requiring reliable protection coordination and streamlined integration with PLCs and SCADA systems.
The EMR-4000-2A0GB1 is covered by Eaton's standard policy: one year from installation or eighteen months from shipment, whichever comes first. Support includes access to Eaton’s specification sheets, videos, and technical resources, with manufacturer guidance available for installation, integration, and ongoing maintenance.
