FAQs
Installation starts with mounting the unit using the projection method and connecting its eight digital inputs and nine outputs to the protection logic. Take advantage of removable terminals for quick field wiring and confirm compatibility with existing Modbus RTU or DNP3 RTU networks over fiber optic ST for reliable SCADA communication.
Key specs include current sensing inputs of 5A and 1A, power supply range of 19-300Vdc or 40-250Vac, and a 50/60 Hz frequency rating. It offers eight digital inputs, nine digital outputs, and protection features like current protection and differential protection to support transformer protection schemes.
Yes. Its 8/9 IO, rugged conformal-coated boards, and fiber-based Modbus RTU or DNP3 RTU communications make it well-suited for transformer protection in both substations and industrial environments. The device supports zone selective interlocking and multiple IO options, enabling precise protection coordination at scale.
Compliance details can vary by region; the data indicates Compliances: Contact Manufacturer. The product features conformal coating for reliability in harsh environments and a one-year Eaton warranty policy, with regional approvals typically documented during order processing or via Eaton’s documentation.
ROI improves through faster fault isolation, reduced downtime, and streamlined integration with SCADA due to integrated Modbus/DNP3 over fiber, fewer field wiring runs thanks to 8/9 IO, and longer asset life from enhanced protection logic. The rugged design and regional availability support lower maintenance costs over time.
