FAQs

The ETR-5000-2A1GB1 supports Modbus RTU or DNP3 RTU communications over RS-485, uses removable terminals for easy wiring, and provides 8 digital inputs with 9 digital outputs plus 2 current-sensing inputs. It is designed to drop into standard transformer protection panels and integrates with existing D-SUB RS-485 networks, simplifying field deployment.
Power supply range covers 19-300 VDC or 40-250 VAC with a 50/60 Hz frequency rating. The device accommodates 5 A or 1 A channel ratings on phase current sensing and provides multiple protection I/O pathways (8 inputs, 9 outputs) to support complex transformer protection schemes and metering needs.
Yes. The ETR-5000-2A1GB1 is purpose-built as a transformer protection relay with modular I/O, RS-485 communication, and compatibility with common SCADA interfaces. Its 8 DI/9 DO and 2 current sensing inputs support differential protection, power protection and metering, enabling fast fault isolation and secure remote monitoring in substations and OEM equipment.
Compliance details for this model are listed as 'Contact Manufacturer' in the data set, with CE, SIL, and IP-related certifications commonly pursued for transformer relays in this class. For exact approvals and country-specific requirements, confirm with Eaton or your local distributor before procurement.
The relay’s robust protection, removable terminals, projection mounting, and conformal-coated boards reduce commissioning time and maintenance downtime. RS-485 remote monitoring via Modbus/DNP3 lowers field visits, while the 1-year (or 18-month from shipment) Eaton warranty mitigates risk. All these factors contribute to lower lifecycle costs and quicker return on investment.
