Item description

The input module directly connects to Pt and Ni resistance sensors.

Two-wire sensors 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.

It features multiple setting options and high accuracy.
