Notice

Fast digital inputs – interference from interfering devices

Please note that the input wiring has very little filtering. It has been optimized for fast signal transmission from the input to the evaluation unit. In other words, rapid level changes/pulses in the µs range and/or high-frequency interference signals from devices (e.g. proportional valves, stepper motor or DC motor output stages) arrive at the evaluation unit almost unfiltered/unattenuated. These interferences can be incorrectly detected as a signal.

  • To suppress interference, an additional input filter can be parameterized.
  • Furthermore, EMC-compliant cabling and the use of separate power supply units for the terminal and the devices causing interference are recommended.
