           This input module directly connects to Pt or Ni resistance sensors and
           potentiometers.
           Two-, three- or four-wire resistance sensors, as well as three-wire potentiometers
           can be connected. The module automatically linearizes the entire temperature
           range. A sensor error (short circuit, wire break or out-of-measurement range) is
           indicated by a red LED. Unused channels can be deactivated.
           The module can be configured via WAGO-I/O-CHECK or GSD files, while
           featuring multiple setting options and high accuracy.
