8 digital inputs and 9 outputs give you versatile protection signaling and alarming options near the transformer. This reduces external wiring and simplifies control-system integration, cutting commissioning time for transformer protection relays. In critical applications such as switchgear bays and distribution substations, the high I/O density supports local diagnostics and fast fault indication, improving overall system reliability. RS-485 Modbus RTU and Ethernet TCP/IP connectivity enables seamless remote monitoring, proactive maintenance, and data sharing with SCADA platforms, reducing downtime and enabling faster response times in fault events. The I/O options include Trip Coil Monitor, URTD interface, IRIG-B, and Sensitive Ground Input, which enhances trip coordination and event tracking for high-stakes protection schemes. These features translate to lower maintenance costs and easier retrofits in aging infrastructure. The power and sensing capabilities align with transformer protection and metering needs, supporting compliance-driven workflows and historical data analytics for asset management. Compatibility with the base ETR-4000 relay family simplifies spare-part provisioning and installation planning.

FAQs

Installation begins with mounting the unit using the Projection mounting method and securing removable terminals for easy wiring. Connect power within the 19-300 Vdc or 40-250 Vac range, then wire the 8 digital inputs, 9 outputs, and 2 analog inputs/outputs to the protection logic and metering sensors. Configure Modbus or DNP3 over RS-485 and Ethernet for SCADA integration, and use the IRIG-B interface and Sensitive Ground Input as required for precise time-stamped events and ground fault detection. Properly sizing and labeling enables straightforward commissioning and reduces field errors.
