Quick Summary

Eaton transformer relay ETR-4000-2A2EA1 provides transformer protection for industrial automation systems and control panels. Engineers often struggle with slow fault isolation and inconsistent protection across Profibus networks in harsh environments. Typical certifications include CE marking and SIL-capable configurations; IP ratings depend on the enclosure and installation—confirm exact scope with Eaton. By combining modular I/O, robust voltage range, and Profibus-DP communication, this transformer protection relay delivers reliable protection coordination and streamlined commissioning for modern automation projects.

FAQs

Begin by mounting the unit using the projection mounting method and securing the removable terminals. Connect the 8 digital inputs and 9 outputs, wire the 2 current sensing inputs, and attach the Profibus-DP communication link via the D-Sub/RS485 port. Verify power supply within the 19-300 VDC and 40-250 VAC range before energizing and performing a basic protection test.
Key specs include a power supply range of 19-300 VDC or 40-250 VAC, 50/60 Hz operation, 8 digital inputs, 9 digital outputs, 2 current sensing inputs, and Profibus-DP over RS485 communication. The device supports 5A and 1A phase current configurations and provides 8 input/9 output capacity for integrated protection logic.
Yes. The relay provides Profibus-DP communication over D-Sub/RS485, enabling direct integration with PLCs and SCADA systems, reducing wiring complexity and enabling centralized fault diagnosis and coordination.
Compliances indicate 'Contact Manufacturer' for official scope. In practice, CE marking and SIL-capable configurations are typical within this product family; however, always verify the exact certification scope and any regional requirements with Eaton for your installation.
The ETR-4000-2A2EA1 reduces downtime through fast fault isolation and integrated protection, lowers wiring and panel complexity with a high I/O count, and offers a reliable, serviceable design with removable terminals. A one-year warranty (up to eighteen months from shipment) further protects your investment and supports total cost of ownership goals.
