ETR-4000-2A3IB0

Quick Summary

The Eaton transformer relay protects transformers within industrial power systems, delivering fast trip logic and diagnostics. Engineers struggle to reliably integrate protection across RS-485 networks and Ethernet without compromising uptime. Note that compliance details, including CE, SIL, and IP ratings, are specified by the manufacturer and the datasheet. This solution also supports Modbus and DNP3 over RS-485 and Ethernet, delivering business value through reliability and easy integration with existing control architectures. With 8 digital inputs and 9 outputs, 50/60 Hz compatibility, and a wide power range (19-300 Vdc, 40-250 Vac), it supports scalable protection schemes. The conformal coating on circuit boards and removable terminals simplify field installations in challenging environments.

8 digital inputs and 9 outputs are embedded, delivering compact, scalable I/O for complex protection schemes; this reduces panel space and wiring costs while enabling fast fault signaling directly to logic controllers. In practical terms, you can deploy differential and current protection with metering in a single housing, speeding commissioning and improving fault visibility in substations and industrial plants. RS-485 and Ethernet Modbus/DNP3 communications are built-in; this enables seamless remote monitoring and coordinated protection across distributed assets, aligning with modern plant networks and remote diagnostics. Power supply flexibility of 19-300 Vdc and 40-250 Vac supports mixed supply environments, reducing inventory requirements for retrofits and new builds. Conformal coating and removable terminals improve field reliability by resisting moisture and dust and simplifying maintenance in harsh environments. IRIG-B, Trip Coil Monitor, and Sensitive Ground Input I/O options add flexibility for high-reliability protection schemes, enhancing synchronization and fault isolation efficiency.
