8 digital inputs and 9 outputs provide flexible protection logic while preserving control integrity. The 2 current-sensing inputs enable accurate protection and metering, reducing nuisance trips and improving coordination across feeders, essential for transformer protection applications and zone selective interlocking. Power is supplied over a wide range (19-300 VDC, 40-250 VAC) with 50/60 Hz compatibility, while removable terminals and projection mounting streamline installation and maintenance, reducing commissioning time and field wiring errors. RS-485 with Modbus RTU and Ethernet TCP support enables secure remote monitoring, SCADA integration, and data-driven maintenance, improving asset visibility and reducing downtime. I/O options such as Trip Coil Monitor, URTD Interface, Sensitive Ground Input, and IRIG-B time synchronization enable precise protection schemes and time-critical operations in demanding environments. The conformal-coated PCBs and Eaton’s 25-000 warranty policy provide long-term reliability and predictable ownership costs for substations and industrial facilities.

FAQs

Install the device using its projection mounting method and secure removable terminals to simplify wiring. Plan for 8 digital inputs and 9 outputs, plus space for the two current-sensing inputs. Ensure the power supply range of 19-300 VDC or 40-250 VAC is met, and connect RS-485 for Modbus RTU and Ethernet for Modbus TCP. Verify grounding per site standards and use the IRIG-B option if precise time stamping is required.
Key specs include 50/60 Hz operation, power supply range 19-300 VDC and 40-250 VAC, 8 inputs, 9 outputs, and 2 current-sensing inputs. Protection functions span Voltage Protection and Metering, Differential Protection, Current Protection and Metering, and Power Protection and Metering. Communications include RS-485 Modbus RTU and Ethernet Modbus TCP, enabling remote monitoring and integration with SCADA systems.
Yes. The ETR-5000-2A1IB1 is designed for transformer protection in distribution substations and industrial facilities, offering 8/9 I/O with zone selective interlocking (2) and support for remote monitoring via RS-485 and Ethernet. Its rugged construction with conformal coating and projection mounting makes it a practical choice for installations requiring reliable protection coordination and fast fault isolation.
Certification and compliance vary by market. Always verify regional requirements with Eaton and the project’s compliance team. In general, consult Eaton for CE readiness, SIL/IEC compatibility where applicable, and any IP-related enclosure protections for harsh environments. The product page notes compliance details via the manufacturer, so confirm current certifications before procurement.
The product is covered by Eaton's Selling Policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. ROI benefits come from reduced downtime, improved protection coordination, remote diagnostics via RS-485 and Ethernet, and easier maintenance through modular I/O and time synchronization features, all contributing to lower operating costs over the equipment's life cycle.
