The EMR-5000-2A0GB0 offers differential protection and sensing across voltage, current, and metering inputs, delivering a fast fault signal that minimizes equipment damage and downtime. This translates to a measurable business impact: higher motor availability, fewer unplanned outages, and improved maintenance planning for power distribution in manufacturing settings. It supports a robust application footprint in motor control panels and drive systems, enabling precise coordination with factory SCADA and energy management systems through Modbus RTU or DNP3 RTU over RS-485, reducing integration time and risk. With 16 digital inputs and 9 digital outputs, operators gain flexible signaling and interlocking capabilities for safe, loop-free control of multiple motor circuits in demanding environments. The URTD interface IRIG-B option ensures time synchronization for accurate event logging in critical power applications. Removable terminals and compatibility with the EMR-4000 base relay simplify retrofit projects, cut commissioning time, and streamline field servicing. The product’s 50/60 Hz operation and wide DC/AC voltage range (19-300 Vdc / 40-250 Vac) expand applicability across diverse motor types, delivering a consistent protection layer from installation to operation. A single, ready-to-integrate device also supports warranty and service programs from Eaton, reducing lifecycle risk and administrative overhead for procurement teams.

FAQs

When retrofitting an EMR-5000-2A0GB0, plan for semi-flush mounting and removable terminals to streamline wiring and future service. The unit is designed to be compatible with the EMR-4000 base relay, enabling straightforward upgrades without a full panel redesign. Ensure RS-485 Modbus RTU or DNP3 RTU networks are correctly terminated and that the 16 digital inputs and 9 digital outputs align with your motor control wiring diagrams for safe control signaling.
Differential protection enables fast detection of internal motor faults by comparing signals across essential parameters, triggering protective actions before damage propagates. This reduces unplanned downtime and extends motor life by isolating faults promptly. In practice, combine this with voltage, current, and metering inputs to create a comprehensive protection scheme in power distribution and drive applications.
Yes, the EMR-5000-2A0GB0 supports Modbus RTU or DNP3 RTU over RS-485. To configure, connect the RS-485 interface to your SCADA or RTU network, set the appropriate baud rate and addressing, and map the device’s DI/DO and protection status to your client tags. This enables remote monitoring, alarms, and control signaling with minimal wiring and fast integration into existing automation architectures.
The product is covered by Eaton’s warranty policy: one year from the date of installation or eighteen months from shipment, whichever occurs first. Compliances are listed as Contact Manufacturer, so verify current CE, IP, or SIL-related certifications with Eaton for your specific deployment and regulatory requirements prior to purchase or field deployment.
This motor protection relay excels in industrial motor control panels, power distribution units, and drive systems across manufacturing, process automation, and utility subsections. Its differential protection, wide voltage range, and RS-485 communication make it ideal for environments requiring reliable protection, precise logging, and scalable integration with SCADA and energy management systems.
