Eight digital inputs and nine digital outputs provide versatile control and signaling for transformer protection schemes, reducing external relay boxes and wiring. This consolidation lowers cabinet depth and installation time, while enabling fast protective signaling for transformer feeders and alarms. The device supports differential protection, power protection and metering functions, enabling accurate fault detection and energy monitoring within substations and industrial plants. Networked communication via RS-485 Modbus RTU and Ethernet TCP allows seamless integration with SCADA, BMS, and remote diagnostics, improving visibility and predictive maintenance. The unit runs on a wide power supply range of 19-300 Vdc or 40-250 Vac and features removable terminals and projection mounting for straightforward installation and field serviceability. Zone selective interlocking, a Trip Coil Monitor, and Sensitive Ground Input enhance protection selectivity and fault isolation in complex power networks. Compatibility with IRIG-B timing and IRIG-based synchronization supports precise coordination in multi-device protection schemes. Overall, these features deliver reliability, reduced downtime, and a faster return on investment for transformer protection projects.

FAQs

Plan for projection mounting and removable terminals to simplify wiring and future maintenance. The relay supports a wide power range (19-300 Vdc, 40-250 Vac) and standard control cabinet mounting, which reduces enclosure depth and wiring complexity. Ensure adequate space for heat dissipation and provision for RS-485 and Ethernet connections to enable remote monitoring and integration with SCADA or protection schemes.
The unit provides Modbus RTU over RS-485 and Modbus TCP over Ethernet (RJ-45), enabling seamless data exchange with protection relays, PLCs, and SCADA systems. This enables remote diagnostics, real-time signaling, and integration into centralized protection schemes, reducing fault response times and enabling coordinated interlocking across multiple devices in a substation or plant.
Certification status for this model depends on configuration and regional requirements; the data indicates ‘Compliances: Contact Manufacturer.’ For safety-critical applications, confirm with Eaton which SIL, CE, or IP ratings apply to your specific configuration and installation conditions to ensure regulatory and safety compliance.
The ETR-5000-2A1IA1 supports differential protection, power protection, and metering functions, along with zone selective interlocking and a Trip Coil Monitor. It includes current sensing inputs (two) and voltage protection and metering features, enabling accurate fault detection, energy measurement, and rapid interlocking for safer transformer operation in demanding environments.
Centralizing protection logic with eight inputs and nine outputs reduces external relays and wiring, cutting maintenance complexity and commissioning time. Remote diagnostics via RS-485 and Ethernet improve MTTR, while removable terminals and projection mounting simplify field servicing. These factors contribute to lower downtime, improved reliability, and a faster return on investment in transformer protection projects.
