WAGO 750-471

WAGO 750-471 – 4 AI Voltage/Current Differential, Galvanically Isolated

Overview

The WAGO 750-471 module processes four differential analog inputs. It supports multiple configurations of voltage and current signal types, from small millivolt ranges to ±10 V, ±20 mA, and NAMUR NE43 ranges. Each channel has 16-bit resolution with galvanic isolation and diagnostics (wire break, over/under range, overload). LEDs provide status per channel. Ideal for precise signal measurement in industrial automation, with flexibility in signal type and robust error detection.

Key Features

• Four differential analog input channels (voltage & current)

• Configurable per channel: voltage or current signal type, range selectable from several options

• Ranges include 0-10 V, ±10 V, ±200 mV; 0-20 mA, 4-20 mA, 3.6-21 mA (Namur NE43), ±20 mA

• Resolution: 16 bits (measured value)

• Galvanic isolation for inputs

• Diagnostics per channel: wire break, overload, over-range / under-range

• LED indicators: channel status / error detection

• Differential input configuration improves noise immunity
