Product Description

The Siemens 6ES5241-5AA21 Module is a SIMATIC S5 Digital Input PLC Module engineered for industrial automation systems. It features 16 digital input channels, supporting 24V DC sensor signals with a rated voltage range of 20.4–28.8V DC. Designed for integration into SIMATIC S5 racks, it connects directly via the system backplane without external cabling. The module operates reliably within a temperature range of 0°C to +60°C, making it suitable for manufacturing, automotive, and heavy machinery applications. Its compact design allows seamless expansion by linking multiple modules within the same rack. Key advantages include high noise immunity, rugged construction for harsh environments, and backward compatibility with S5 platforms. Drawbacks include limited modern protocol support and dependence on legacy S5 architecture. The module lacks built-in displays, batteries, or wireless interfaces, prioritizing focused digital input functionality for discrete signal acquisition. Detection distance depends on connected sensors, with typical thresholds aligned with 24V industrial standards.
