🎥 As a PLC expert, you should have a basic understanding of the physical components that make up a PLC system, and you should know each one of the PLC hardware components is designed to perform a specific function.

By watching this video, you’ll get the answer to the following questions:
How to power a PLC?
What is PLC power supply?
How much power does a PLC use?
How to select power supply for PLC?
How to connect power supply to PLC?
How does PLC power supply module work?

======================================================

💬 Video Summary:

Typically, the first module is a power supply that comes in different powers and sizes.

The most common input voltage to a power supply is 120 or 230-volt AC. From this point, the power supply regulates and converts the AC input voltage to the DC output voltage, mostly 24-volt DC.

To power up all other PLC modules to work correctly, we usually do the wiring between the power supply and each individual PLC component.

In case of power supply, we need to consider two factors. First, the power supply we choose must provide the power needed for all PLC modules to keep the PLC system stable.

And secondly, there is no data exchange between the power supply and other PLC components because the main job of the power supply is to provide the power needed by the PLC modules.
