2/4-channel analog input; Resistance measurement; Adjustable This analog input module directly connects to Pt or Ni resistance sensors and potentiometers. It can be operated as a 2-channel (2- and 3-wire) or 4-channel (2-wire) module. The module automatically linearizes the entire temperature range. A sensor error (short circuit, line break or measurement range overflow) is indicated by a red LED. The module can be configured via WAGO-I/O-CHECK or GSD files. It features multiple setting options and high accuracy.
