FAQs

Begin by confirming the base relay (ETR-4000) compatibility and ensure the device is powered within the 19-300 Vdc / 40-250 Vac range. Install the unit using the removable terminals in projection mounting, route data and control wiring to the 8 digital inputs and 9 outputs, and configure protection logic to coordinate with upstream and downstream protection devices. Use Modbus/DNP3 TCP for integration with SCADA and ensure proper grounding and shielded fiber connections for remote monitoring.
Key specs include 8 digital inputs, 9 outputs, 2 current-sensing inputs, and power supply ranging from 19-300 Vdc to 40-250 Vac, with 50/60 Hz operation. These enable precise fault detection, flexible metering, and scalable protection schemes. The wide voltage range supports diverse source configurations, while the current sensing inputs improve accuracy for differential and directional protection decisions.
Yes. The device is designed for transformer protection in electrical networks, with flexible IO, metering capabilities, and compatibility with industry-standard communication protocols. Its 50/60 Hz operation supports global grids, and the wide input range accommodates various distribution configurations. For substation or plant-level protection, pair it with appropriate trip logic and coordination schemes to meet your protection philosophy.
Compliance information is provided by the manufacturer, with current listing indicating 'Compliances: Contact Manufacturer.' Verify CE, UL, or IP ratings directly with Eaton to ensure alignment with your project’s regulatory requirements. The unit also features conformal-coated circuit boards to improve reliability in harsh environments, which can be important for certain industrial applications.
ROI benefits come from reduced external IO hardware, centralized protection logic, and improved fault diagnosis via integrated metering and remote communications, which can shorten downtime and maintenance cycles. Regular maintenance should include periodic verification of wiring integrity, inspection of removable terminals, and testing Modbus/DNP3 communications with SCADA to ensure reliable remote monitoring.
