Description
This course gets you up to speed on understanding what makes up an industrial control panel.  An overview of IEC Basic panel design criteria and standards is provided.

IEC schematics and how to read them is covered.

These electrical schematic diagrams are often used in small to large scale electrical control systems.  Stand alone machines, infrastructure equipment, integrated assembly lines, resorts, theme parks and building automation systems, use these types of electrical schematic diagrams.

An example IEC industrial control panel schematic set is provided in the course.

Important topics are covered in this course:

The main parts and basic construction of an IEC industrial control panel

Introduction to IEC industrial control panel standards

Overview of utilization categories for low voltage switch gear

Back panel component layouts, including din rail and wire routing ducts is explained

PLC graphic layout and back panel layout are detailed

Basic emergency stop control circuits are outlined

Safety control module integration is covered

Safe torque off or STO variable frequency drive safety function is covered

What makes up an industrial control schematic set

How IEC page coordinate systems work
