Eaton distribution relay EDR-3000-2B1BA0 - RS485 Modbus
Part Number: EDR-3000-2B1BA0
Quick Summary
The Eaton distribution relay EDR-3000-2B1BA0 provides reliable feeder protection and monitoring for industrial power systems. Engineers often struggle to integrate multi-protocol relays while maintaining accurate, real-time status as plant conditions vary, causing delays and miscoordination. Certification considerations include CE, SIL, and IP ratings—confirm these with Eaton to ensure regulatory compliance, supplier support, and safe operation in harsh industrial environments. Beyond protection, the unit's RS485 Modbus RTU and DNP3 RTU communications enable scalable SCADA integration and data-driven maintenance across feeders. Coupled with straightforward installation and strong warranty coverage, this relay supports faster project delivery and longer asset life in manufacturing, utilities, and data centers.

Eaton Specification Sheet - EDR-3000-2B1BA0
Flexible power and I/O configurations enable rapid deployment across diverse feeder installations. The EDR-3000-2B1BA0 operates over a broad power range of 19-300 Vdc and 40-250 Vac, with 8 inputs and 6 outputs, plus a base relay (EDR-3000) ready for expansion. Removable terminals and semi-flush mounting simplify wiring in tight panels, reducing installation time and the chance of loose connections in industrial environments. The device supports Current Sensing inputs for metering and protection coordination, enabling accurate load profiling and faster fault localization. These attributes translate to less commissioning effort, greater reliability in harsh conditions, and a lower total cost of ownership over the product lifecycle.\n\nCommunication is a core differentiator for modern feeder control. RS485 guarantees robust long-distance signaling, while Modbus RTU or DNP3 RTU enables seamless data exchange with SCADA, distributed control systems, and energy-management software. This makes centralized monitoring, remote diagnostics, and alarm escalation practical across multiple feeders from a single interface. In practice, engineers can implement zone-selective interlocking and time-stamped event logs without rewriting existing communication schemas. The 8/6 I/O structure provides plenty of headroom for bus couplers, coil monitors, and protective relays, reducing the need for additional controllers and simplifying spare-part inventories.\n\nProtection, safety, and support in one package. The unit includes a Sensitive Ground Input, Trip Coil Monitor, and current protection and metering capabilities that support precise protective coordination and nuisance-trip mitigation. With its rugged mechanical approach, including a semi-flush mount and removable terminals, field service is faster and less error-prone. Eaton’s specification sheet and multimedia resources help validate configurations during design reviews and commissioning, improving overall return on investment.

FAQs
Installation for the EDR-3000-2B1BA0 begins with verifying the 19-300 Vdc / 40-250 Vac supply and the eight inputs by six outputs configuration. Use the removable terminals for a clean, secure connection and plan semi-flush mounting in a spacious panel. Enable Sensitive Ground Input and Trip Coil Monitor per your feeder protection scheme.
Modbus RTU over RS485 enables straightforward SCADA integration by providing a common communications path for real-time status, metering data, and fault reports. The DNP3 RTU option further supports interoperability with remote telemetry systems. This reduces field visits and accelerates fault diagnosis, while allowing centralized control of multiple feeders from a single HMIs or EMS.
SIL, CE, and IP certification details should be confirmed with Eaton before deployment. While the device is designed for robust feeder protection, ensure the manufacturer confirms compliance to your regional standards, and obtain installation and maintenance procedures. This helps ensure regulatory alignment and reduces risk during audits and system commissioning.
Key performance specifications include 8 inputs, 6 outputs, 50/60 Hz operation, and a 19-300 Vdc / 40-250 Vac power range, suitable for diverse feeder configurations. Protection features leverage Current Protection and Metering, plus a Sensitive Ground Input and Trip Coil Monitor for accurate coordination and fast fault isolation, minimizing unplanned downtime.
Warranty follows Eaton policy 25-000: one year from installation or 18 months from shipment, whichever occurs first. Technical support is available through Eaton's product pages and authorized distributors, with specification sheets, datasheets, and installation videos to aid commissioning, maintenance planning, and ongoing performance optimization.
