ALLEN-BRADLEY 1794 FLEX I/O Product

  • Individually configurable channels allow the module to be used with a variety of sensors
  • Selectable input filters on many modules allow to select from several different filter frequencies for each channel, lower filter settings provide greater noise rejection and resolution, higher filter settings provide faster performance
  • Single-ended or differential inputs depending on module, analog modules have single-ended inputs while isolated analog and temperature modules have differential inputs, single-ended voltage sensors reduce costs, differential inputs are typically more noise immune
  • Standards: C/US UL listed, CE-EMC marked, C-TICK certified, GOST_R certified, KCC certified, MARINE-ABS certified, MARINE-BVS certified, MARINE-DNV certified, MARINE-GL certified, MARINE-KRS certified, MARINE-LR certified, ROSTECHNADZOR, RUS_PAT_APPR
  • Applications: For in-cabinets
