FAQs

Consider removable terminals and projection mounting for straightforward commissioning and maintenance. Plan for 8 digital inputs and 9 digital outputs to match your protection scheme, and ensure Profibus-DP RS485 wiring is correct for seamless network integration. Grounding, enclosure selection, and environmental protection should align with the Conformal Coated Circuit Boards specification to maximize reliability in industrial settings.
Yes. The device is designed for 50/60 Hz operation and supports a wide power supply range of 19-300 Vdc and 40-250 Vac, enabling operation across varying plant voltages without extensive reconfiguration. This flexibility helps reduce inventory needs and simplifies troubleshooting in mixed-voltage facilities.
It is ideal for transformer protection, differential protection and metering, and integration into PROFIBUS networks for centralized control. The 8 input / 9 output configuration supports complex interlocking, fault signaling, and monitoring in substations, manufacturing plants, and utility-scale transformer installations.
The product documentation indicates Compliances: Contact Manufacturer. For regulatory marks such as CE or UL, and any IP ratings, verify with Eaton’s official datasheet and support. This ensures you meet local and industry regulatory requirements before deployment.
The device consolidates protection functionality into a single relay with 8 inputs and 9 outputs, reducing wiring complexity and panel space.
