Wago 750-431 8Di, 24 Vdc 0.2ms

Why Choose the WAGO 750-431 8-Channel Digital Input Module?

The WAGO 750-431 is a high-density 8-channel digital input module designed for the WAGO I/O System 750. It allows PLCs and industrial controllers to monitor 24 V DC digital signals from sensors, switches and machine contacts, enabling reliable signal acquisition across distributed automation systems.

The module receives digital control signals from field devices and transmits their switching state to a WAGO fieldbus coupler or programmable controller. Integrated noise-rejection filtering prevents electrical interference or transient spikes from being interpreted as valid input signals, improving operational reliability in industrial environments.

With eight input channels in a compact DIN rail module, the 750-431 provides efficient use of cabinet space while maintaining reliable signal processing. The module includes power jumper contacts for field supply distribution and uses WAGO CAGE CLAMP® spring pressure terminals for fast, secure wiring within control panels.
