Quick Summary

Eaton transformer relay ETR-5000-2B1BA1 provides robust transformer protection for industrial power systems. Engineers often struggle to find a single device that protects, communicates, and wires cleanly in compact panels. Certification status varies by region, so confirm with Eaton for CE, SIL, or IP ratings and the latest compliance documentation. The unit supports Modbus RTU or DNP3 RTU over RS485 and offers flexible I/O to simplify integration with protection schemes. Its wide power input range and removable terminals translate into faster commissioning, reduced panel space, and lower total cost of ownership.

FAQs

Begin by verifying your panel cutouts accommodate the 8.06 in L x 8.7 in H x 9.72 in W form factor and ensure a 19-300 Vdc / 40-250 Vac supply across 50/60 Hz. Mount using the projection method and connect removable terminals for quick field wiring. Wire 8 digital inputs, 2 analog inputs, 2 analog outputs, and 9 digital outputs as required by your protection scheme. Connect RS485 to a Modbus RTU or DNP3 RTU master, then configure the base relay (ETR-4000) as the control node and perform a site test prior to commissioning.
Key specifications include a power supply range of 19-300 Vdc and 40-250 Vac, 50/60 Hz operation, 8 digital inputs, 9 digital outputs, 2 analog inputs, 2 analog outputs, and Modbus RTU or DNP3 RTU over RS485 communication. It supports differential protection, voltage protection and metering, power protection and metering, and current protection and metering, with a Zone Selective Interlocking level of 2. This combination enables flexible protection and precise coordination.
Yes. The ETR-5000-2B1BA1 is designed as a transformer protection relay with rugged I/O, broad voltage and frequency compatibility, and RS485 network options for remote monitoring. Its 8/9 I/O configuration, metering capabilities, and time-synchronized inputs (IRIG-B option) make it well-suited for substations, switchgear, and OEM panel builders seeking integrated protection and control without importing multiple devices.
Warranty is Eaton’s policy: one year from installation or eighteen months from shipment, whichever comes first. Compliance status is provided by the manufacturer; confirm regional CE, SIL, or IP documentation with Eaton. For protection equipment, always verify the latest compliance sheets and regional certifications before deployment and maintain the official Eaton Selling Policy 25-000 documentation as reference.
Maintenance benefits include time-synced signaling with IRIG-B, removable terminals that simplify wiring checks, and projection mounting that speeds field servicing. ROI is driven by improved fault isolation via RS485 remote monitoring, reduced panel space, fewer external I/O modules, and consolidated protection functions in a single device, lowering both capital and operating costs over the life of the transformer protection scheme.
