Product Description

The **6ES5244-5AA51 module** is a digital input component designed for integration with **Siemens PLC** systems, specifically supporting the **SIMATIC S5 interface**. It features 32 high-density digital input channels for direct sensor connectivity without additional expansion modules. Operating within a voltage range of 20.4–26.4V DC, it ensures stable performance in industrial environments with temperature tolerance from 0°C to 60°C. Ideal for automation, manufacturing, and process control applications, this module offers rugged construction for reliable signal acquisition in harsh conditions. While lacking built-in communication ports or battery backup, its primary strengths include simplicity, high channel density, and compatibility with legacy S5 systems. Drawbacks include limited scalability compared to newer PLC platforms. Input detection typically supports standard industrial sensor ranges (e.g., 0–24V thresholds). Compact dimensions ensure easy installation in control cabinets.
