Wago 750-430/025-000 8Di, 24 Vdc 3ms T

Why Choose the WAGO 750-430/025-000 8-Channel Digital Input Module?

The WAGO 750-430/025-000 is a high-density 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 for distributed automation systems.

Each module receives digital signals from field devices and transmits their switching state to a connected WAGO fieldbus coupler or programmable controller. The module integrates a 3 ms noise-rejection filter to prevent electrical interference or transient spikes from causing false switching signals. :contentReference

With eight digital inputs within a slim 12 mm DIN rail housing, the module provides excellent channel density while minimising cabinet space. The design also includes electrical isolation between field and system levels to improve operational safety and signal integrity in industrial environments. :contentReference
