WAGO 750-403

WAGO 750-403 – 4 DI 24 VDC, 0.2 ms High-Side Switching

Overview

The WAGO 750-403 module is a 4-channel digital input module in the WAGO I/O System 750/753 series. It accepts 24 VDC inputs via high-side switching with a fast 0.2 ms input filter for clean signal detection. Each channel includes status indication with LEDs. The module is electrically isolated between system and field sides and is designed for compact mounting on DIN rails.

Key Features

• Four digital input channels, 24 VDC

• High-side switching characteristic (active when input sees 24 V)

• Very fast input filter of 0.2 ms to reject brief glitches

• LED indicators for each input channel (status)

• Electrically isolated system vs field sides (500 V)

• Slim width (~12 mm) for dense panel layout

• Standard connection via CAGE-CLAMP® terminals
