Feature: Eight digital inputs, nine outputs, and two current-sensing inputs enable centralized protection logic, metering, and fast fault indication across transformer assets. Business Impact: The expanded I/O set reduces wiring complexity, minimizes panel footprint, and lowers install labor by eliminating multiple discrete relays. Application: Deploy in distribution panels, switchgear housings, and OEM equipment where compact protection and orchestrated signaling are required for rapid trip decisions. Feature: Power supply range spans 19-300 Vdc and 40-250 Vac with a 50/60 Hz rating, enabling operation from mixed plant power architectures. Business Impact: Flexible power conditioning supports retrofits and new builds without costly panel rewiring, while maintaining consistent protection performance. Application: Best suited for facilities with diverse supply voltages, portable test benches, and installations near variable grid conditions. Feature: Profibus-DP communication over fiber optic ST enables deterministic, noise-immune data exchange between the relay and the host control system. Business Impact: Improves remote diagnostics, reduces communication-induced downtime, and simplifies integration with existing automation architectures. Application: Ideal for distributed protection schemes in substations, OEM production lines, and energy-management systems requiring synchronized data across devices. Feature: Conformal-coated circuit boards, removable terminals, and projection mounting simplify rugged installation and maintenance in dusty, humid, or temperature-variant environments. Business Impact: Increases field reliability, extends service intervals, and facilitates quick swap-outs during maintenance windows. Application: Use in harsh manufacturing floors, cable troughs, and cabinet environments where space is tight and service access is limited. Feature: I/O options such as Trip Coil Monitor, IRIG-B time synchronization, URTD Interface, and Sensitive Ground Input expand controller capabilities for protection coordination. Business Impact: Supports precise time stamping, coordination with other protection devices, and improved fault discrimination under dynamic loading. Application: Essential in zones with high interlocking requirements, complex transformer banks, and utility-grade protection schemes.

FAQs

The ETR-4000-2A3DB1 includes Profibus-DP communication over fiber optic ST, enabling deterministic, noise-resistant data exchange with a host PLC or SCADA. This integration reduces wiring complexity, improves diagnostic visibility, and supports synchronized protection signaling across distributed transformer protections in substations and large OEM installations.
The unit supports a power supply range of 19-300 Vdc and 40-250 Vac at 50/60 Hz, with eight digital inputs, nine outputs, and two current-sensing inputs. It also offers meter and differential protection functions, enabling comprehensive transformer monitoring and fast fault signaling within a compact protection relay.
Yes. The device provides zone selective interlocking (2), current protection, differential protection, and metering capabilities. This enables precise fault discrimination and coordinated protection across transformer banks, reducing outage impact and supporting reliable protection coordination in large facilities and substations.
Consider its projection mounting and removable terminals for straightforward panel integration. The unit also uses conformal-coated circuit boards, enhancing durability in dusty or humid environments. Dimensions and weight (approx. 8 in depth, 9.72 in width, 8.7 in height, ~9.3 lb) support compact retrofits in existing switchgear or control cabinets.
