Siemens 6ES5454-4UA12 Digital Output Module

Why This Output Module Fits Your S5 System

This digital output module controls sixteen load circuits independently. You get a high-density Siemens 6ES5454-4UA12 for SIMATIC S5 programmable controllers. It drives solenoids, relays, and indicator lamps with reliable switching. Therefore, your system saves valuable rack space with its compact design.

Technical Specifications and Physical Details

The Siemens 6ES5454-4UA12 provides sixteen output channels in a single slot. Each channel handles up to 0.5 amps of continuous current at 24V DC. 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 0.50 kg for straightforward installation. This output card stores no configuration data internally. Instead, the CPU holds all logic and state information. 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 output returns. The Siemens 6ES5454-4UA12 features screw-type terminals for secure wiring. Therefore, field connections remain stable even with vibration. Always add a freewheeling diode across inductive loads. This practice prevents voltage spikes from damaging the output transistors.
