Siemens 6ES5475-5AA11 Analog Output Module S5 4-Channel

Technical Overview

The 6ES5475-5AA11 analog output module converts digital control signals into precise analog voltages or currents for field devices. This module features 4 isolated output channels for driving actuators such as valves, positioners, and variable-speed drives. It supports both voltage outputs (0 to 10V) and current outputs (0 to 20mA or 4 to 20mA). The integrated D/A converter ensures high resolution and low drift for accurate process control.
