Eaton EBR-3Z-2B0EB1-B Bus differential relay - Profibus-DP

Eight digital inputs and six digital outputs provide integrated I/O for feeder protection. This consolidation reduces wiring complexity and cabinet footprint, speeding panel assembly and commissioning. Used in industrial feeders, it supports synchronized signaling and local interlocking across multiple devices. Flexible power and electrical range ensures compatibility with mixed-voltage plants and retrofits without extra supplies, lowering total installed cost by simplifying procurement and spares planning. Applications include utility feeders, machine lines, and distribution panels. Profibus-DP RS485 / D-SUB interface enables straightforward integration with automation networks. The business impact is faster data collection, easier remote diagnostics, and reduced field wiring. This is ideal for facilities adopting Profibus networks or migrating from legacy interfaces. Mechanical and serviceability features—projection panel mounting and removable terminals—permit quick installation and simple maintenance. Conformal-coated circuit boards improve reliability in harsh environments, while a -20 to 60°C operating range supports both outdoor and indoor spaces. Together these features reduce downtime and extend service intervals. Operating and performance data—5 A contact rating supports reliable switching of feeder circuits, with 40-250 Vac and 19-300 Vdc sensing. The robust specification set helps meet uptime targets in critical processes while maintaining compliance with internal electrical protection schemes.
