The input/output module DIO248, DIO264 and DIO280 are used for controlling digital consumer like contactors, relays, pneumatic and hydraulic valves, as well as for reading signals of digital working sensors, detectors or switches. On events can be reacted expressly via 8 available interrupt inputs. Alternatively there are available up to four counters, for detecting e.g. positions or counting goods. For the energy-saving operation of inductivities all outputs can be operated as PWM. Especially for the PWM operation of valves a hold time is additionaly configurable between 0 up to 2 s. Outputs are parallel connectable, in case it is operated in the same operation mode.



  • 48/64 or 80 digital channels
  • 16 channels can be configured as input or output
  • Configurable interrupt inputs
  • Configurable 32 bit counter
  • Mode: event counter, incremental encoder, gate measurement, cycle time or frequency measurement
  • Configurable input filter
  • PWM output mode for e.g. valve economy mode
  • Status display for each channel via LED
  • Supply voltage 18 to 34 VDC
  • Supply voltage protected against reverse polarity
  • Cost effective and space saving
