Siemens 6ES5465-4UA Analog Input Module

The Siemens 6ES5465-4UA Analog Input Module is a 16-channel analog input block for the SIMATIC S5 peripheral range (465), designed in a compact, non-isolated (potenzialgebunden) form factor to connect analog sensors directly to the S5 controller. The family includes variants such as 6ES5465-4UA12, which accepts current inputs in the 0..20 mA range with a bridge option to 4..20 mA and requires a separate measuring-range module, and 6ES5465-4UA13, which provides voltage measurement (Spannungsmessung) in a non-isolated configuration. Each variant delivers 16 input channels and is intended for reading signals from process and factory sensors, including current-loop transmitters and voltage-type sensors, enabling applications like level, temperature, and pressure monitoring within older Siemens S5 installations. The module is built for direct integration with the S5 peripheral bus, serving as the front end for converting field signals into digital data for the controller. It is part of Siemens’ 465 analog input module family, offering a compact alternative to larger I/O assemblies while maintaining the ability to interface with 4–20 mA and voltage sensors in legacy automation architectures.
