FAQs
Projection mounting and removable terminals simplify on-site wiring and field upgrades. Plan space within the panel to accommodate the 8 input/9 output I/O layout, and pre-wire connectors to minimize commissioning time. Confirm clearance for access to removable terminal blocks for future maintenance and diagnostics.
The relay supports current/voltage sensing protections and metering across 5A/1A phase current inputs, with differential and power protection metering as part of the sensing inputs. Configure through the device interface or engineering documentation to align with generator protection schemes and zone selective interlocking requirements.
Yes. The device includes Profibus-DP communication over D-Sub/RS-485, enabling integration with existing PLCs and SCADA systems. This helps with remote diagnostics, centralized protection logic, and streamlined data exchange for control room visibility.
Certification details are provided by the manufacturer. Confirm regional requirements such as CE, SIL, and IP ratings with Eaton to ensure the relay meets local safety and environmental standards for your installation and regulatory context.
By reducing nuisance trips, enabling precise protection, and simplifying network integration, you can expect lower downtime and faster fault resolution. The relay’s modular I/O, diagnostic visibility, and easier wiring contribute to lower maintenance labor costs and smoother asset lifecycle management.
