Siemens 6ES5244-3AA13 Simatic S5 PLC Interface Module

Siemens 6ES5244-3AA13 is a SIMATIC S5 IP 244 Temperature Control Module that provides dedicated temperature sensing and regulation for older S5 PLC systems. This TC/RTD/mV input module accepts thermocouple (TC), resistance temperature detector (RTD), and millivolt sensor signals, enabling precise temperature monitoring and control within process and manufacturing applications. Built for use on the SIMATIC S5 IP 244 backplane, the module integrates with S5 controllers to form compact temperature control loops in classic industry environments. The 6ES5244-3AA13 is a plug‑in expansion module designed to reside in a compatible S5 rack, delivering reliable temperature data to the PLC’s logic and output modules for regulation tasks. In practice, it supports multiple sensor types in a single module, simplifying wiring and integration in legacy automation setups. This part is commonly used in legacy Siemens automation environments where precise temperature measurement and control are required, and it remains a key component for maintaining existing S5‑based temperature control loops.
