Specification

SEODescription

The **6ES5256-3AB11** is a **Siemens SIMATIC S5 256** series **digital module** designed for industrial automation. This module provides **32 digital I/O channels** (16 inputs and 16 outputs) with a **24V DC operating voltage**, enabling direct interfacing with sensors, actuators, and other control devices. It supports integration into SIMATIC S5 systems via a parallel bus interface, allowing connection to multiple expansion modules for scalable configurations. Operating within a **temperature range of 0°C to 60°C**, it is suited for harsh environments in manufacturing, process control, and machinery. Key advantages include high reliability, rugged construction, and compatibility with legacy S5 systems. However, its lack of modern communication protocols (e.g., PROFIBUS or Ethernet) limits flexibility in advanced automation setups.
