Siemens 6ES5460-4UA12 Digital Input Module For S5 PLC

The Siemens 6ES5460-4UA12 SIMATIC S5 460 analog input module provides eight galvanically isolated analog inputs for SIMATIC S5 PLCs, enabling direct sensing of voltage or current signals. As part of the 460 analog input family, the 4UA12 range submodule configures four channels at a time with measurement ranges of ±10 V or 0–20 mA, allowing flexible interfacing to common sensors. The module reads analog signals from process sensors and feeds digital values to the S5 CPU, supporting applications such as temperature, pressure, level, and flow monitoring in industrial automation; its input isolation enhances protection and noise immunity within legacy systems. It uses the SIMATIC S5 bus architecture and pairs with matching range submodules to cover voltage and current signals, making it suitable for expanding existing S5 installations that require robust analog input channels without replacing the entire control platform.
