WAGO 750-402 digital input module with 4 channels for 24V DC signals designed for the WAGO I/O System 750/753 distributed automation platform.
£41.72
The WAGO 750-402 is a compact 4-channel digital input module designed for the modular WAGO I/O System 750/753. It receives 24 V DC signals from field devices such as sensors, switches and push buttons and transmits these signals to the PLC through the system bus for monitoring and automation control.
Each input channel incorporates a built-in signal filter to suppress noise and ensure stable signal detection in electrically demanding industrial environments. The module also provides electrical isolation between field wiring and system electronics, improving system reliability and protecting control equipment.
With its slim design and robust CAGE CLAMP® spring pressure connection technology, the module allows quick installation, secure wiring and efficient use of space inside control cabinets and distributed I/O assemblies.
Digital input modules are essential for monitoring field devices in industrial automation systems. The WAGO 750-402 converts signals from sensors, switches and other field equipment into process data that can be used by PLC controllers and industrial control systems.
Within the modular WAGO I/O System 750/753, this module integrates seamlessly with fieldbus couplers and controllers, enabling scalable distributed control architectures across industrial plants and machine automation systems.
