  • Such input / output units with voltage connections are particularly cost-effective.
  • Such sensors can not be connected to such input / output units with voltage connections, which provide a current signal as a measuring signal.
  • it is often desirable for reasons of precision to use as sensors such sensors which provide a current signal as a measuring signal since such sensors, which provide a current signal as a measuring signal, are less sensitive to electromagnetic interference than sensors which provide a voltage signal as a measuring signal.
  • Such electromagnetic interference can occur when loads are turned on or off near the sensors.
  • sensors that provide a current signal as a measuring signal is that they can be positioned at a great distance to the input / output unit, as a large wiring length and thus a large Wiring resistance does not affect the accuracy of the measurement signal.
  • sensors, which provide a current signal as a measurement signal are to be integrated into a control-technical or control-technical system, separate input / output units must be kept ready for them. This is disadvantageous for cost reasons. There is therefore a need for a low-cost input / output unit to which sensors which provide a voltage signal as a measurement signal and sensors which provide a current signal as a measurement signal can be connected to one another.
  • the invention is based on the object to provide a novel input / output unit of a control engineering or control system.
