WAGO Kontakttechnik 750-409 Programmable Logic Controller Module

The WAGO Kontakttechnik 750-409 PLC Module is a four-channel digital input module in the WAGO-I/O-SYSTEM 750 series that interfaces 24V DC digital signals with PLCs and control networks. It uses Cage Clamp connection, is designed for DIN rail mounting, and provides integrated LED indicators for quick status monitoring, housed in industrial thermoplastic for an industrial-rated operating range. This module supports modular expansion within the WAGO 750 Series I/O Systems and is commonly used to monitor sensors, switches, and discrete field devices in packaging lines, conveyors, process skids, OEM equipment, and control panels, enabling reliable distributed remote I/O and automation retrofits or I/O replacements. Common replacements include the WAGO 750-402, 750-400, and 750-430.
