Eaton distribution relay EDR-3000-2C1BA1 - RS485 Modbus/DNP3

Power-supply flexibility and rugged mounting: EDR-3000-2C1BA1 accepts 19-300VDC or 40-250VAC at 50/60 Hz, with projection mounting and removable terminals. This simplifies panel integration, reduces wiring errors, and speeds commissioning on new builds or retrofits in substations and industrial plants. Industry-standard communications: The unit supports Modbus RTU or DNP3 RTU over RS485, enabling seamless data exchange with DCS, SCADA, and energy meters. In practice, reliable remote monitoring and control translates into faster fault diagnosis and improved operator situational awareness. Sensing and protection: With 1 current-sensing input and configurable feeder protection, the device supports phase currents of 5A and 1A per channel, aiding accurate metering and protection coordination. Zone selective interlocking (ZSI) reduces fault propagation and minimizes outage impact. I/O and timing options: Four inputs and four outputs provide versatile control logic, while optional IRIG-B sensitive ground input supports precise timing for synchronized protection schemes. This makes it suitable for feeders requiring coordinated protection and metering across multiple panels. Reliability and service: The device is backed by Eaton's warranty and support program; installation and configuration can be expedited with available datasheets and training resources. By consolidating protection, metering, and communication in a single relay, operating costs decrease and uptime improves.
