WAGO 753-461

WAGO 753-461 – RTD Resistance Analog Input Module

Overview

The WAGO 753-461 is a 2-channel analog input module designed for direct connection of Pt and Ni resistance temperature detectors (RTDs). It supports 2-wire and 3-wire sensor connections and provides automatic linearization across the full temperature range. Each channel includes diagnostics for short circuits and wire breaks, with LED indication for operation and errors. Shield connections are tied directly to the DIN-rail for noise immunity.

Key Features

• Two RTD/resistance sensor inputs

• Supports Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni1000

• 2-wire or 3-wire connection per channel

• Resolution of 0.1 °C

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

• Linearization over the full measurement range

• Measuring current ~0.5 mA typical

• Error diagnostics with LED status indicators

• Shielding connected to DIN-rail for improved EMC

• Galvanic isolation between system and field side
