Product Description

The Siemens 6ES5257-4UA11 is a SIMATIC S5 expansion module designed to extend PLC system capabilities. This PLC interface module supports 32 digital input/output channels, enabling direct connection for up to 8 additional expansion units via its integrated parallel interface. Operating within 24V DC (±15%) and a temperature range of 0-60°C, it ensures stability in industrial environments like manufacturing automation and process control. The module lacks built-in communication ports (e.g., RS-485/Profibus), requiring external adapters for network integration. Its key advantages include rugged construction, backward compatibility with S5 systems, and low power consumption. Limitations include no native battery backup or display, making it unsuitable for standalone applications. Features like screen size and detection distance are not applicable to this interface module. Ideal for legacy system upgrades, it balances reliability with limited scalability in modern automation frameworks.
