Siemens 6ES5464-8MB11 Industrial Control System PLC Module

Siemens 6ES5464-8MB11 is a four-channel analog input module for the SIMATIC S5 family, specifically configured as an isolated 464 input card. It provides four isolated analog inputs that accept voltage signals in the ±1 V range, converting them into process data for the S5 CPU. Designed for use with S5-90U, S5-95U, and S5-100U processors and compatible with ET 100U and ET 200U input units, this module plugs into the SIMATIC S5 backplane to extend the system’s analog sensing capability. Its isolation between input channels and the backplane protects the controller and field wiring from common-mode transients while delivering consistent, multiplexed analog values to the PLC. Typical applications include acquiring low-level voltage signals from sensors such as temperature probes, pressure transducers, or other field devices where a narrow ±1 V range provides the required resolution and noise performance. The part number is 6ES5464-8MB11, commonly described as SIMATIC S5 analog input module 464-8MB11.
