Product Description

The Siemens 6ES5260-5AA21 module is a robust SIMATIC S5 digital I/O unit engineered as a direct replacement for aging S5-100U systems in industrial automation. This module integrates 16 digital inputs and 16 digital outputs, operating at 24VDC with a tolerance range of 20-30VDC. Designed for harsh environments, it functions reliably within a temperature range of 0°C to 60°C and supports seamless integration into legacy PLC configurations, allowing direct connection to up to 8 expansion modules. Widely used in manufacturing, automotive, and process industries, its key advantages include high durability, backward compatibility, and plug-and-play installation. However, it lacks modern communication protocols like Profibus or Ethernet, requiring adapters for contemporary networks. The compact design prioritizes functionality over non-essential features, omitting display screens or onboard batteries, ensuring focused performance in critical control applications.
