WAGO 750-460 – 4 AI Resistance Measurement for Pt RTD Sensors

Overview

The WAGO 750-460 is a 4-channel analog input module designed for connecting Pt resistance temperature detectors (RTDs). It supports 2-wire Pt sensors and converts resistance into temperature values using internal linearization. The module features built-in diagnostics for wire breaks, short circuits, and measuring range overflow, indicated with LEDs. It is ideal for precise industrial temperature measurement.

Key Features

• Four analog input channels for 2-wire Pt RTD sensors (e.g., Pt100, Pt1000)

• Automatic linearization across the full temperature range

• Diagnostic LEDs for wire break, short circuit, or overflow errors

• High resolution of 0.1 °C

• Wide measurement range: −200 … +850 °C

• Electrical isolation between system and field side (500 V)

• Compact 12 mm module width
