WAGO 750-454 Input Module

WAGO 750-454 Overview

The WAGO 750-454 is a 4-channel analog current input module belonging to the WAGO-I/O-SYSTEM 750 series. It is used to convert analog current signals from field devices into digital signals that can be processed by WAGO controllers.

Product Detailed Description

• Function:

• Receives 4 independent analog current signals from field devices.

• Converts these current signals into 12-bit or 16-bit (configurable) digital values.

• Transmits the digital values to the controller via the WAGO I/O bus.

• Provides electrical isolation to protect the control system from voltage spikes and interference on the field side.

• Supports single-ended inputs.

• Features:

• 4 analog current input channels.

• Configurable input ranges (e.g., 0-20 mA, 4-20 mA).

• Optional 12-bit or 16-bit resolution.

• Diagnostics per channel (e.g., wire break detection).

• LEDs indicate the status of the module and channels.

• Compact, modular design for easy installation and expansion.
