Why Choose the WAGO 750-404/000-003 4-Channel Digital Input Module?
The WAGO 750-404/000-003 is a reliable 4-channel digital input module designed for the WAGO I/O System 750/753. It captures 24 V DC signals from field devices such as sensors, switches and push buttons and transfers these signals to the PLC or automation controller via the system bus.
Each input channel incorporates an integrated noise-rejection filter to ensure stable signal detection in demanding industrial environments where electrical interference may occur. The module also provides electrical isolation between the field wiring and internal system electronics, improving system reliability and protecting control equipment.
Using WAGO’s proven CAGE CLAMP® spring pressure connection technology, the module enables quick wiring, secure electrical connections and efficient installation within compact distributed I/O assemblies.
