Quick Summary

The Eaton transformer relay provides real-time transformer protection and metering for industrial power systems. Engineers often struggle with integrating protection schemes and communications in tight spaces. Key certifications commonly expected in this class include CE marking for Europe, IP-rated robustness, and SIL-ready configurations. This device combines Modbus RTU or DNP3 RTU over RS-485 with multi-IO, enabling fast wiring, straightforward commissioning, and reduced project risk. Customers gain faster time-to-value thanks to its modular IO, removable terminals, and conformal-coated boards suitable for demanding environments. Additionally, its flexible power supply range and standard communication protocols simplify integration with existing protection schemes and SCADA systems.

Feature: 8 digital inputs and 9 digital outputs enable rich monitoring and control. Business Impact: Expanded visibility and precise control reduce fault duration and enable zone-selective interlocking. Application: Transformer protection schemes, feeders, and motorized protection. The device also supports 2 analog inputs and 2 analog outputs for metering and control signals, enabling more granular energy measurement and protective logic in substations. Feature: Modbus RTU or DNP3 RTU over RS-485 supports centralized monitoring and integration with existing SCADA systems, lowering engineering effort and commissioning time. Application: OEMs and panel builders can deploy standard communication methods with minimal custom gateways. Feature: Dual power supply ranges 19-300 Vdc and 40-250 Vac accommodate both plant DC and AC rails, easing installation and reducing inventory. Application: Works across varying plant voltages and ensures compatibility with legacy panels. Feature: Conformal coating and removable terminals improve field reliability and serviceability in harsh environments. Application: Industrial facilities subject to vibration, dust, and humidity benefit from long-term reliability and fast maintenance.

FAQs

Begin with the 19-300 Vdc or 40-250 Vac power supply and mount the unit in a compliant enclosure. Use the removable terminals for clean, reliable wiring of 8 digital inputs and 9 digital outputs, plus the 2 analog inputs and 2 analog outputs. Follow the wiring diagram in the Eaton datasheet and verify Modbus/RS-485 connectivity for your network.
The relay supports Modbus RTU or DNP3 RTU over RS-485 via a D-Sub connector. Configure device address, baud rate, parity, and protocol selection on the PowerPort-E interface per the user manual. Ensure proper RS-485 line termination and isolated grounding where required to prevent noise.
It provides transformer protection and metering across voltage, current, and differential schemes, plus zone selective interlocking and multiple I/O options. The 5A and 1A current sensing options enable accurate fault detection, while the 8/9 I/O count supports protective logic, trip signaling, and monitoring in one device.
Verify CE marking for European compliance and confirm any IP enclosure rating and SIL readiness with Eaton for your application. The manufacturer lists compliance guidance as available on request, so consult Eaton for any project-specific certifications and appropriate installation standards.
By consolidating protection, metering, and communications in a single device with removable terminals and conformal coating, maintenance minimizes downtime and simplifies spare part inventories. The one-year warranty (or 18 months from shipment) supports ongoing reliability, while straightforward commissioning reduces project risk and speeds time-to-value.
