Siemens 6ES5464-8MB11 Industrial Automation IO Module

Siemens 6ES5464-8MB11 is a four‑channel analog input module for SIMATIC S5 controllers, providing galvanic isolation between its inputs and the backplane. It is designed for use with S5 CPUs such as 90U, 95U, and 100U, and is compatible with ET 100U and ET 200U peripheral interfaces. Each of the four channels accepts a voltage signal within a ±1 V range, enabling precise reading of low‑level sensor voltages and transducer outputs. The module ships in its original packaging, ensuring it arrives in factory condition for replacement or retrofit in legacy S5 automation setups. In operation, the AI464‑series module converts analog voltage signals into digital data that the SIMATIC S5 CPU can process for monitoring and control tasks, helping to integrate sensor measurements into the control program. With four isolated inputs in a compact package, this 6ES5464‑8MB11 unit supports straightforward expansion of existing S5 I/O configurations, aiding reliable signal acquisition in applications such as process sensing, instrumentation, and test rigs where small‑signal voltage measurements are required. Its Siemens lineage and compatibility with established S5 backplanes and ET interfaces support consistent integration within mature control architectures without necessitating major system topology changes.
