Siemens AG 6ES5441-4UA14 Digital Output Module

Siemens 6ES5441-4UA14 is a 32‑channel digital output module designed for the SIMATIC S5 family. It provides 24 V DC outputs with a rated current of 0.5 A per channel, arranged in two 16‑point banks in a non‑isolated compact design for backplane mounting in S5 racks. This card is part of the 441‑4UA14 digital output family and is used to switch 24 V DC loads such as coils, contactors, indicator lamps, or other actuators directly from the S5 processor. The two 16‑point groups map to standard S5 I/O backplanes, with a common return for all outputs as is typical for non‑isolated designs. It is designed to plug into compatible SIMATIC S5 bases (for example S5‑135U/S5‑155U) and provides a practical 32‑point I/O solution for legacy automation projects requiring multiple discrete outputs in a single card.
