Siemens 6ES5441-4UA13 Programmable Logic Controller Module

Siemens 6ES5441-4UA13 is a 32-channel digital output module for SIMATIC S5 systems, designed to connect 24 V DC loads and deliver up to 0.5 A per channel; it is compatible with S5-135U/-155U/H controllers and acts as a compact extension to the I/O rack. The UA13 variant is specified as non-floating and compact version U, meaning the outputs share a common reference and are intended for direct connection to the backplane back to the S5 rack; it occupies a standard I/O slot. Each of the 32 digital outputs switches 24 V DC loads controlled by the S5 CPU, enabling centralized, scalable control of multiple devices in a machine or process panel without requiring separate wiring for each channel. This module is part of Siemens' SIMATIC S5 digital I/O family, commonly used in older manufacturing equipment and control panels that still rely on the S5 architecture. Typical applications include expansion of output capability for discrete control tasks in S5-based systems.
