What is the Wago 750-458?

This analog input module directly connects to thermocouples.

The module automatically linearizes the entire temperature range.

Cold junction compensation mitigates the clamping unit offset voltage over the 0–55°C operating range.

A line break 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.
