Siemens 6ES5243-1AA13 Programmable Logic Controller Module

Siemens 6ES5243-1AA13 is an IP243 analog input module designed for SIMATIC S5 PLC systems, expanding the controller’s ability to capture analog signals from sensors and convert them into digital data for the PLC to process. Marketed as a full configuration IP243 analog module, it includes a 1 A/D transformer, enabling integrated analog-to-digital conversion within the S5 expansion bus and simplifying wiring by reducing external components. This module is intended for use in compatible Siemens S5 racks and should be paired with a CPU and bus configuration that supports IP243 modules to ensure correct addressing and reliable data transfer in legacy automation setups. As part of the IP243 family, the 6ES5243-1AA13 provides a dedicated analog input interface within the SIMATIC S5 ecosystem, enabling dependable measurement of sensor signals and feeding these values into control logic, data logging, or process monitoring routines that rely on real-world analog inputs.
