WAGO 750-450

WAGO 750-450 – 4 AI Resistance / RTD / Potentiometer

Overview

The WAGO 750-450 module accepts resistance measurements from RTD (Pt or Ni) sensors and potentiometers, with support for 2-, 3-, or 4-wire configurations. It automatically linearizes over its measurement range and includes LED indicators for sensor errors such as wire break, short circuit, or out-of-range. Unused channels can be deactivated. It is built for precise resistance/temperature sensing in modular I/O systems.

Key Features

• Four analog input channels for resistance / RTD / potentiometer sensors

• Supports Pt100, Pt200, Pt500, Pt1000; Ni100, Ni120, Ni1000 sensors; and potentiometers up to specified resistances

• 2-, 3-, and 4-wire configurations depending on sensor type

• Automatic linearization of the full temperature range

• LED diagnostics for channel error conditions (short circuit, wire break, range overflow)

• Configurable signal types per channel (sensor selection, wiring configuration)

• Unused input channels can be disabled to save resources

• Strong measurement performance with good resolution and error margins
