Siemens 6ES5470-4UC11 Analog Output Module

Technical Overview

The Siemens 6ES5470-4UC11 is an analog output module for the SIMATIC S5-135U programmable controller series. This module converts digital values from the CPU into precise analog signals for controlling field devices. It provides four isolated output channels, each configurable for either 0–10V voltage or 0–20mA current signals. The module transmits the analog values with 11-bit resolution, ensuring high accuracy. It also features a front-facing connection for flexible and accessible wiring. A 24V DC external supply powers the module, which then supplies the outputs to the actuator.
