Analog Output (AOUT) Modules are essential PLC modules to drive analog actuators. The analog output has the highest cost per channel among all IO modules and possibly the most challenging to protect. There are multiple topologies to implement analog output modules to achieve required performance at a designed for cost. Understanding these topologies and why designer can choose them is key factor in selecting the right parts for your AOUT project.
This overview includes the AOUT module key parameters, understanding how the AOUT affect the topology selection, and what different topologies are available to choose from.
