Eaton EDR-3000-2A0BB1 Distribution Relay - RS485 Modbus
Part Number: EDR-3000-2A0BB1
Quick Summary
The Eaton EDR-3000-2A0BB1 distribution relay monitors and controls feeders in industrial power distribution. Engineers often struggle with reliable remote signaling and scalable integration across Modbus RTU or DNP3 RTU networks. Certification details such as SIL, CE and IP ratings are not listed in the provided data; please consult Eaton's current documentation for confirmation. When available, these approvals help reduce operational risk and ease regulatory audits. This unit features four inputs and four outputs, supports 19–300 Vdc or 40–250 Vac power, and communicates over RS-485 using Modbus RTU or DNP3 RTU, enabling simple integration with feeder controllers and SCADA. The result is improved system reliability, better fault visibility, and streamlined procurement through a single, compatible relay.
