Eaton motor relay EMR-5000-2A1IB1 - 50/60 Hz, RS-485 & Ethernet

Wide voltage and protection range enables investment protection across both DC and AC motors, supporting 19–300 Vdc and 40–250 Vac with 50/60 Hz operation. This delivers a tangible business impact by reducing the incidence of nuisance trips and enabling seamless operation in mixed-voltage facilities; ideal for manufacturing and processing lines where uptime is critical. The EMR-5000-2A1IB1 offers 16 digital inputs and 9 digital outputs, enabling sophisticated interlocks and logic control that translate to faster fault detection and safer start-up sequences. In practice, this means fewer manual interventions and more predictable plant performance, which is essential for OEMs and end users deploying multi-motor systems. Removable terminals simplify installation and maintenance, saving service time during commissioning and field upgrades, while compatibility with the EMR-4000 base relay ensures a scalable protection architecture for growing plants. RS-485 and Ethernet TCP communications enable remote monitoring and integration with SCADA, PowerPort-E workflows, and Eaton’s E-Series ecosystem, improving visibility and reducing on-site maintenance visits. The sensing inputs cover Voltage, Power, Current Protection and Metering, plus Differential Protection, delivering comprehensive protection that supports energy efficiency initiatives, accurate fault analysis, and compliance with utility requirements. Zone selective interlocking (ZSI) of 1 enhances selective fault isolation, reducing damage and downtime in fault events. Overall, the device aligns with ongoing Industry 4.0 initiatives by enabling data-driven maintenance and faster troubleshooting while supporting a global 50/60 Hz footprint for international deployments.
