Wago 750-404/000-004 Up/Down Counter,

Why Choose the WAGO 750-404/000-004 4-Channel Digital Input Module?

The WAGO 750-404/000-004 is a compact 4-channel digital input module designed for use with the modular WAGO I/O System 750/753. It receives 24 V DC signals from sensors, switches and other field devices and transmits them to the PLC or industrial controller via the internal system bus.

Each input channel incorporates an integrated noise suppression filter that ensures stable signal detection in electrically demanding industrial environments. The module also provides electrical isolation between field wiring and system electronics, protecting the automation system while maintaining reliable operation.

With its slim DIN-rail design and proven CAGE CLAMP® spring pressure connection technology, the module allows fast wiring, secure electrical connections and efficient use of space in distributed control cabinets and automation systems.
