The revised version of the DPC31 STEP C ASIC for PROFIBUS slaves has been released for delivery.

  • Lower price: Price reduction of 10% (exception: Development package with 6 pcs.)
  • New functions, in particular DPV2 (alarms and isochrone mode)
  • Lower current consumption / power losses in PROFIBUS-PA mode with new 2MHz technology.
