Wago 750-430 8Di, 24 Vdc 3ms

Why Choose the WAGO 750-430 8-Channel Digital Input Module?

The WAGO 750-430 is a compact 8-channel digital input module designed for the WAGO I/O System 750. It enables PLCs and industrial controllers to monitor 24 V DC digital signals from sensors, switches and other field devices, providing reliable signal acquisition within distributed automation systems.

The module receives control signals from digital field devices such as proximity sensors, switches and transmitters, converting them into process data for a connected WAGO fieldbus coupler or programmable controller. Each channel includes an integrated noise-rejection filter with a 3 ms time constant, ensuring stable signal detection in industrial environments. :contentReference

With eight digital inputs in a slim 12 mm housing, the module provides high channel density while maintaining minimal cabinet space requirements. Electrical isolation between the system and field levels improves operational safety, while CAGE CLAMP® spring pressure connection technology ensures secure vibration-resistant wiring. :contentReference
