WAGO 750-402

WAGO 750-402 – 4 DI 24 VDC, 3 ms High-Side Switching

Overview

The WAGO 750-402 is a 4-channel digital input module in the WAGO I/O System 750/753. It accepts 24 VDC input signals, using high-side switching with a 3 ms noise-rejection filter to guard against signal bounce. The module is electrically isolated between system and field sides, has per-channel LEDs for status indication, and is designed for compact DIN-rail usage with a slim 12 mm width.

Key Features

• Four digital input channels, 24 VDC

• High-side switching input characteristic

• Noise-rejection filter with 3 ms time constant

• LED status indicators for each input channel

• Electrical isolation (system vs field)

• Compact width (~12 mm) for space-efficient installation

• Uses CAGE-CLAMP® terminals for wiring reliability
