UO-EM-D2 / UO-EM-D41 SIL 2 FOC decoder module


UO-EM-D2 / UO-EM-D41 SIL 2

U-ONE Generation I – FOC decoder module

System solution U-ONE

  • Decoding FOC signals of the U-ONE basic units
  • Power further U-ONE function modules
  • Central programming interface RS 232
  • Options: SIL 2 / PL d certification (UO-EM-D41)


U-ONE Generation I – FOC decoder module

FOC decoder modules convert optical FOC signals from the basic units of the universal encoders to electric signals and feed them on to other function modules of the U-ONE system. The fiber optic cables are connected via ST connectors, the supply voltage via a terminal strip.
