Eaton ETR-4000-2A3EA0 Transformer Relay - Profibus-DP RS485

Feature → Business Impact → Application: The ETR-4000-2A3EA0 provides eight digital inputs and nine outputs, enabling complex protection schemes and status signaling that translate to quicker fault isolation and reduced downtime in transformer feeders. This capability directly supports improved protection coordination and faster diagnostics, applicable in utility substations and manufacturing plants where transformer reliability is critical. Feature → Business Impact → Application: Profibus-DP over D-Sub and RS-485 communications ensure seamless PLC/SCADA integration, lowering integration costs and enabling centralized monitoring across the plant floor. This is ideal for process automation environments needing reliable data exchange with existing control architectures. Feature → Business Impact → Application: A broad power-supply range of 19–300 Vdc and 40–250 Vac, 50/60 Hz compatibility, reduces site-specific adapters and simplifies global deployment, cutting spare-part inventories and maintenance overhead. Feature → Business Impact → Application: Zone selective interlocking (2) and IRIG-B interface improve selective fault clearance and time synchronization, enhancing system reliability in high-demand industrial networks. Feature → Business Impact → Application: Removable terminals and semi-flush mounting ease field installation and service, minimizing panel downtime and simplifying retrofits in constrained electrical rooms.
