Item description
This input module directly connects to Pt or Ni resistance sensors and potentiometers.
The connection of 2-, 3- or 4-conductor resistance sensors is possible. Potentiometers are connected with 3-wire technology.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.
It features multiple setting options and high accuracy.
