Product Description

The Siemens 6ES5244-5AA21 module is a SIMATIC S5 digital I/O PLC module designed for industrial automation applications. This robust module features 16 digital inputs and 16 digital outputs, enabling direct integration with field devices in manufacturing and process control systems. It operates within a 24V DC voltage range (20.4–28.8V) and supports extended temperature operation from 0°C to 60°C. The module interfaces seamlessly with SIMATIC S5 PLC systems via proprietary communication protocols and can connect to multiple expansion units for scalable I/O configurations. Known for high reliability and industrial-grade durability, it is widely used in machinery, automotive, and heavy industries. While lacking modern communication interfaces like Ethernet/IP or PROFINET, its simple design ensures compatibility with legacy S5 systems. The module requires no onboard battery or display, focusing purely on robust I/O functionality in harsh environments. Key advantages include easy installation and backward compatibility, though limitations include restricted protocol support compared to newer Siemens PLC modules.
