Siemens SIMATIC 6ES5242-1AA31 Digital I/O Module for SIMATIC S5 PLC systems, designed for industrial automation with reliable signal interface and integration in S5 control setups.

Product Description

The Siemens SIMATIC 6ES5242-1AA31 is a Digital I/O Module designed for the SIMATIC S5 PLC system, offering 16 digital I/O channels (8 inputs and 8 outputs) with 24V DC operation. It supports direct connection of up to 8 expansion modules and integrates seamlessly with S5 PLC racks. Operating within a temperature range of 0–55°C and a voltage range of 20–30V DC, this module features high noise immunity and galvanic isolation for reliable performance in industrial automation, manufacturing, and process control applications. While lacking built-in communication interfaces, it excels in robustness and compatibility with legacy S5 systems. Its compact design and screw-type terminals simplify installation, though its dependency on the aging S5 architecture may limit modern integration capabilities.
