FAQs

EMR-3000-2A1HB1 uses projection mounting and a compact footprint designed for panel-friendly installation. It supports four digital inputs, four digital outputs, and a single analog output, allowing you to consolidate control signaling inside a standard control cabinet. When planning retrofit projects, verify panel dimensions, cabling clearance, and the URTD interface requirements to ensure clean wiring and straightforward integration with existing PLCs or HMIs.
Key specs include 5A/1A phase current handling, 50/60 Hz operation, and the presence of a single analog output with four digital inputs and four digital outputs. The unit supports IEC 61850 over Ethernet RJ-45 and Modbus/DNP3 TCP, enabling flexible communication with modern automation architectures. Ensure your power and signal wiring complies with URTD interface requirements for accurate protection and metering.
Yes. The EMR-3000-2A1HB1 includes IEC 61850 communications over Ethernet RJ-45, along with Modbus and DNP3 TCP for broader interoperability. This makes it well-suited for modern substation and plant automation environments where standardized, vendor-agnostic data exchange is critical for protection, monitoring, and coordinated control of motor-driven equipment.
Compliance details are provided by the manufacturer and may require verification for CE, SIL, or IP ratings. The product carries Eaton’s standard warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. For definitive certification status, consult Eaton documentation or contact the manufacturer directly prior to purchasing for your regulatory requirements.
The device consolidates motor control, protection, sensing, and timing in a single relay, reducing wiring complexity and the need for multiple standalone modules. This can lower installation labor, simplify diagnostics via integrated metering, and improve uptime through robust protection features. Compatibility with industrial Ethernet protocols supports easier integration into ongoing maintenance and upgrade programs.
