FAQs
Installation involves mounting the relay with its semi-flush method and securing removable terminals for easy wiring. Ensure the 16 digital inputs and 9 outputs are correctly connected to your protection scheme, then configure the communication link to your PLC via RS-485 or PROFIBUS-DP. Follow the manufacturer’s documentation for sequence programming and protective relay settings to minimize start-up faults.
Verify the power supply range (19-300 Vdc, 40-250 Vac) and the frequency rating (50/60 Hz). Confirm the presence of 16 digital inputs, 9 digital outputs, 2 current sensing inputs, and 5 A / 1 A selectable current sensing. Also validate PROFIBUS-DP over D-Sub / RS-485 communication and timing features like IRIG-B for synchronized protection trips.
Yes. The relay supports PROFIBUS-DP over D-Sub and RS-485, enabling straightforward integration with existing PLCs and SCADA systems. This compatibility reduces commissioning time, simplifies diagnostics, and improves real-time protection visibility across the automation network.
The product data lists compliance as ‘Contact Manufacturer,’ indicating no explicit certification details are published in the data. For project-specific regulatory requirements (CE, SIL, IP), consult Eaton’s technical support or your regional distributor to confirm applicable approvals and any field-adjustable settings.
The relay consolidates multiple protection functions into a single device with extensive I/O and rugged construction (conformal coating, removable terminals). This can reduce wiring, shorten commissioning, and lower field maintenance costs. In practice, improved trip coordination and remote diagnostics translate to reduced downtime and faster fault resolution, yielding measurable uptime and reliability benefits.
