KFD2-UFT-Ex2
  • 2 inputs
  • Control circuit EEx ia IIC
  • Input frequency 1 mHz ... 5 kHz
  • Analog output 0/4 mA ... 20 mA
  • Measuring range parameterisable
  • 2 relay outputs
  • 2 electronic outputs, isolated
  • Each output individually parameterisable as trip value, serially switched output, direction of rotation, synchronization monitoring or error message output
  • Start-up override
  • Lead breakage (LB) and short-circuit (SC) monitoring
  • Debounce filter
  • Parameterization via PC or control panel (optional)

Please note: All product-related documents, such as certificates, declarations of conformity, etc., which were issued prior to the conversion under the name Pepperl+Fuchs GmbH or Pepperl+Fuchs AG, also apply to Pepperl+Fuchs SE.
