Siemens 6ES5434-4UA11 Digital Input Module

Why This Input Module Suits Your S5 System

This digital input module captures signals from sixteen field devices. You get a high-density Siemens 6ES5434-4UA11 for SIMATIC S5 programmable controllers. It reads status from switches, sensors, and push buttons. Therefore, your system monitors many points without using extra rack slots.

Technical Specifications and Physical Details

The Siemens 6ES5434-4UA11 provides sixteen input channels in a single slot. Each channel accepts 24V DC signals from standard industrial sensors. This module fits into a standard S5 rack slot. Its dimensions measure approximately 250 mm in width and 25 mm in height. The unit weighs around 0.48 kg for straightforward installation. This input card stores no configuration data internally. Instead, the CPU holds all filtering parameters and input states. Consequently, you lose no settings during a module replacement.

Below is the detailed breakdown of the hardware specifications.

Installation and Wiring Notes

This module connects directly to field devices using a front connector. You must use a common ground for all input returns. The Siemens 6ES5434-4UA11 features screw-type terminals for secure wiring. Therefore, field connections remain stable even with vibration. Always route input cables away from power lines. Electrical noise will cause false triggering and intermittent signal reading.
