Siemens 6ES5470-4UA12 Analog Input Output Module

Siemens 6ES5470-4UA12 is an 8-channel analog output module for the SIMATIC S5 470-series PLCs, offered in a floating, compact "U" variant. Each of its eight outputs can deliver either a voltage or current signal, with ranges of -10 to +10 V or 0 to 20 mA, and every channel is independently isolated from the others to minimize interference and ground loop issues. The module is designed for use in S5-135U/-155U configurations and supports a maximum channel-to-channel potential difference of up to 60 V AC or 75 V DC. It draws about 250 mA from a 5 V supply, typical for these compact analog output modules. With a 1024-level per-channel resolution, it provides precise control for analog actuators and instrumentation. The UA12 variant is characterized as a floating, compact option within the 470-series, suitable for applications such as valve control, servo or motor speed references, and analog signal generation in older S5 installations. The part number 6ES5470-4UA12 identifies the 8-output, -10 V/0–20 mA capable module that sits in the analog I/O family once used in mid- to late-generation Siemens PLC deployments.
