Siemens 6ES5464-8MC11 Programmable Logic Controller Module

Siemens 6ES5464-8MC11 is a four-channel analog input module (AI 464) for SIMATIC S5 control systems, designed to connect sensors and transducers to S5-90U/95U/100U CPUs and ET 100U or ET 200U backplanes. It provides galvanic isolation between the analog inputs and the backplane to help protect the PLC from voltage spikes and ground differences. Each of the four channels accepts signals in the ±10 V range, enabling direct connection to common process sensors and transducers without additional signal conditioning. As part of the SIMATIC S5 analog input family, this module supports reliable data acquisition for monitoring, process control, and data logging in legacy installations, and it serves as a spare-part option for maintaining older S5 systems. The compact AI 464 form factor and compatibility with standard S5 backplanes make it straightforward to retrofit or replace a failed analog input channel in existing lines.
