Why Choose the WAGO 750-423 4-Channel Digital Input Module?
The WAGO 750-423 is a robust 4-channel digital input module designed for the WAGO I/O System 750. It allows PLCs and industrial controllers to monitor 24 V AC/DC digital signals from field devices such as sensors, switches and control contacts, enabling reliable status detection across automation systems.
This module captures digital signals from connected field devices and transfers their state to a WAGO fieldbus coupler or programmable controller. Each channel incorporates a noise-rejection input filter to improve signal stability and ensure accurate detection in electrically demanding environments. :contentReference
