    Parameters 2.2 Parameter description Parameter description Smoothing The individual measured values are smoothed by digital filtering. The smoothing can be adjusted in four steps, in which the smoothing factor k multiplied with cycle time of the electronic module equals the time constant of the smoothing filter. The greater the smoothing, the greater the time constant of the filter.

  • Page 21: Connecting

    Connecting Connecting measuring sensors Introduction You can connect different measuring encoders to the analog input module: ● Current transmitters as: – 2-wire transmitters – 4-wire transmitters In this chapter you will find out how to connect the measuring encoders and what to watch out for when doing so.
  • Page 22 Connecting 5.1 Connecting measuring sensors Connecting measuring encoders to analog inputs There can only be a limited potential difference U (common mode) between the measuring lines of the input channels. To ensure that the permitted value is not exceeded, you must take different steps depending on the whether the encoders are isolated or non-isolated.
  • Page 23 Connecting 5.1 Connecting measuring sensors Isolated measuring encoders The isolated measuring encoders are not connected to the local ground potential. These can be potential-free. Depending on local conditions or interference, potential differences U (static or dynamic) can occur between the measuring lines M- of the input channels and the reference point of the measuring circuit M The permitted value for U must not be exceeded, even in environments with strong EMC...
  • Page 24 Connecting 5.1 Connecting measuring sensors Non-isolated measuring encoders The non-isolated measuring encoders are connected to the local ground potential. Depending on local conditions or interference, potential differences U (static or dynamic) can occur between the locally distributed measuring points. If the permitted value for U is exceeded, there must be equipotential bonding conductors between the measuring points.
