WAGO Kontakttechnik GmbH & Co. KG 750-402 Digital Input Module

The WAGO 750-402 Digital Input Module is a four-channel, 24V DC digital input card in the WAGO-I/O-SYSTEM 750 that collects discrete signals from field devices and transmits them to PLCs and control systems. Designed for DIN-rail mounting with Cage Clamp connections and a 1-Wire input wiring option, it delivers reliable remote I/O integration for industrial automation. Its integrated LED indicators provide clear channel status, and the industrial thermoplastic housing supports an industrial operating range. Typical applications include packaging equipment, conveyor systems, process skids, OEM machinery, and factory control panels where monitoring proximity sensors, pushbuttons, limit switches, and safety contacts is critical. The 750-402 is commonly used for automation retrofits, failed module replacements, machine control upgrades, and expanding distributed I/O within the WAGO 750 Series, with compatible replacements including 750-400 and 750-430.
