FAQs
Install using the semi-flush mounting and removable terminals for quick access. Connect 8 DI, 9 DO, 2 AI, and 2 AO to your drive logic and motor control circuits, then link via LC fiber Ethernet for IEC 61850 or Modbus/DNP3 networks. The removable base simplifies field upgrades from EMR-4000 and reduces commissioning time.
Key specs include 19-300 Vdc and 40-250 Vac voltage ranges, 50/60 Hz operation, and current paths of 5A/1A. I/O counts are 2 AI, 2 AO, 8 DI, and 9 DO. The device uses removable terminals and supports IP-ready, fiber-based Ethernet communication for reliable network integration.
Yes. The EMR-5000-2B1KA0 supports IEC 61850 over LC duplex fiber optic Ethernet and also accommodates Modbus TCP / DNP3 TCP, enabling seamless integration into modern substations and plant automation networks while preserving robust protection and metering capabilities.
Remote diagnostics and centralized protection data reduce onsite maintenance frequency. The removable terminals and replaceable base simplify field service, while the integrated metering and protection features minimize downtime. The warranty—per Eaton policy—offers protection against early-life failures, enhancing total cost of ownership in industrial environments.
The EMR-5000 extends the EMR-4000 with expanded I/O (2 AI/2 AO, 8 DI/9 DO), additional communication options (fiber-based IEC 61850, Modbus/DNP3), IRIG-B timing, and Sensitive Ground Input support, enabling more complex protection schemes and tighter synchronization for large motor arrays in modern automation architectures.
