Flexible power range supports both 19-300 VDC and 40-250 VAC, enabling installation across varied panel layouts without rewiring. This flexibility reduces parts stock and simplifies commissioning, lowering project costs while maintaining accurate feeder protection in mixed-supply environments. Eight digital inputs and six digital outputs enable direct wiring to PLCs and protection schemes, delivering precise signaling and rapid isolation to minimize downtime in critical processes. The Profibus-DP interface (RS485/D-SUB) simplifies integration with existing automation networks, reducing engineering time and ensuring deterministic communications for coordinated protection. Removable terminals and standard mounting improve installation efficiency, enabling quick maintenance and future upgrades without enclosure redesign. A modest burden of 10 W / 17 VA, 50/60 Hz operation, and a wide operating temperature range (-20 to 60°C) enhance reliability in harsh industrial environments while supporting energy-conscious designs and longer component life.

FAQs
Begin with standard mounting in the panel. Use the removable terminals for wiring the eight digital inputs and six digital outputs, connect the power supply within 19-300 Vdc or 40-250 Vac, and configure the Profibus-DP RS485/D-SUB interface to your PLC network. Verify secure connections, verify voltage ranges, and perform a functional test to ensure proper fault signaling and coordination with other protection devices.
Key specs include power supply range of 19-300 Vdc / 40-250 Vac, 50/60 Hz operation, 5 A contact rating (AC/DC), and a burden of 10 W / 17 VA. The device supports 8 digital inputs and 6 digital outputs, enabling robust fault signaling. It uses bus differential protection to quickly isolate faults on feeder channels and minimize impact on the broader electrical system.
