WAGO Kontakttechnik 753-400 Digital Input Module

The WAGO 753-400 Digital Input Module delivers two 24V DC digital inputs within the WAGO-I/O-SYSTEM 753 for distributed remote I/O in industrial automation. Designed for DIN rail mounting with Cage Clamp wiring, it provides a compact interface between field devices—such as proximity sensors, pushbuttons, limit switches, and safety contacts—and PLC or control systems. Its 1-Wire wiring configuration simplifies connections, while integrated LED channel indicators give at-a-glance status. This 2-channel module supports seamless expansion in WAGO 753 series I/O setups and is compatible with common replacements like 753-409, 750-400, and 750-402, making it suitable for automation retrofits, control panel expansions, and machine upgrades in packaging lines, conveyors, OEM equipment, process skids, and industrial control panels. The module’s industrial thermoplastic housing ensures robust performance in demanding environments while maintaining compact modularity for scalable distributed remote I/O applications.
