WAGO Kontakttechnik 750-409 Digital Input Module

The WAGO Kontakttechnik 750-409 Digital Input Module is a 4-channel digital input card for the WAGO-I/O-SYSTEM 750 that converts field signals into PLC-ready inputs for reliable discrete signal acquisition. It is designed for DIN-rail mounting in industrial panels, uses Cage Clamp wiring, and encases the electronics in an Industrial Thermoplastic housing with integrated LED status indicators, supporting modular expansion within the 750 Series I/O Systems. The module accepts 24V DC inputs from devices such as proximity sensors, pushbuttons, and limit switches, and is commonly used in conveyor automation, packaging lines, assembly machinery, and process control applications where robust digital sensing is required. Common replacements include 750-402, 750-400, and 750-430.
