Three channel optical fibre receiver for real time remote lightning impacts notification in wind turbines.

For use with the DL EOLOS K15FO High bandwidth lightning strike counter.

DL EOLOS FO-RCVR-3CH optical fibre receivers can receive the event notification signals generated by up to three DL EOLOS K15FO high bandwidth lightning strike counters. DL EOLOS FO-RCVR-3CH optical fibre receivers have a compac design for direct 35mm DIN rail installation in the wind turbine's electrical cabinet. These devices provide three independent channels with one optical fibre input and one normally open galvanically isolated relay output per channel. The output configuration allows connections to a wide range of models and formats of programmable logic controllers (PLC).

Characteristics

The DL EOLOS FO-RCVR-3CH receives, analyses and decodes the event notification signals generated by the DL EOLOS K15FO counters in real-time. The fast signals received from the DL EOLOS K15FO counters are processed to produce slower event notification pulses at the outputs. DL EOLOS FO-RCVR-3CH receivers operate from a standard 24V power supply.

  • Three independent channels comprising one optical fibre input and one isolated contact output per channel.
  • Isolated contact outputs with one contact in common for easier interface to other modules and systems.
  • Highly robust to electromagnetic interferences.
  • Vibration resistant optical fibre and output contact connectors.
  • Direct insertion into standard 35mm DIN rails.
  • Visual indication of activity and current state.
  • Wide temperature range of -20ºC to 60ºC
