Product Description

The Siemens 6ES5256-3AA11 is a SIMATIC S5 programmable logic controller (PLC) module designed for digital input/output (I/O) applications. This module integrates 16 digital inputs and 16 digital outputs, providing direct connectivity to peripheral devices. It supports modular expansion, enabling seamless integration with up to 8 additional modules within the S5 system framework. Operating within a voltage range of 24V DC ±10%, the module functions reliably in industrial environments with temperatures spanning 0°C to 60°C. Compatible with standard industrial communication protocols of the S5 series, it is widely utilized in manufacturing automation, process control, and machinery systems. Key strengths include rugged design for harsh conditions, high noise immunity, and backward compatibility with legacy S5 setups. Limitations include lack of native support for modern fieldbus interfaces and limited onboard diagnostics. The module does not incorporate a battery, display, or sensing components, as it is strictly an I/O interface unit. Its compact form factor optimizes space efficiency in control cabinets.
