Specification

SEODescription

The Siemens 6ES5244-5AA11 is a SIMATIC S5 Digital Input PLC module designed for industrial automation, featuring 16 digital input channels compatible with 24V DC signals. It integrates seamlessly into SIMATIC S5 systems, supporting direct connection to sensors and switches via its 24V DC interface. Operating within a voltage range of 20-30V DC and a temperature range of 0-60°C, it ensures reliable performance in harsh environments such as manufacturing, process control, and machinery. The module communicates via the S5 backplane bus, enabling straightforward integration with other S5 components. Key advantages include rugged construction, high noise immunity, and compatibility with legacy S5 systems. However, as part of the discontinued S5 series, it lacks modern communication protocols and may require adapters for integration with newer platforms like S7. Ideal for retrofitting or maintaining existing S5-based automation setups.
