Product Description

The Siemens SIMATIC 505 6ES5240-5AA51 PLC module is a versatile automation component designed for industrial control systems. This module features 16 digital inputs and 16 digital outputs, enabling direct connectivity for multiple expansion modules, supporting scalable configurations. It includes built-in RS-232 and RS-485 communication interfaces for seamless integration with field devices and SCADA systems. Operating within a voltage range of 20.4–28.8 V DC, it functions reliably in harsh environments with an operating temperature range of -25°C to +60°C. Ideal for manufacturing, process control, and material handling industries, the 6ES5240-5AA51 offers robust performance and modular flexibility. Key advantages include high noise immunity and easy diagnostics, though limited support for modern protocols may require additional adapters. The module incorporates a backup battery (typically 3.6 V lithium) for memory retention during power loss. While it lacks an integrated screen, its compact design ensures space-efficient installation, supporting precise I/O signal detection within a 24 V DC range.
