Q & A

What is the main topic of the video?

The main topic of the video is about the sourcing and sinking concepts in PLC logic.

Why is understanding sourcing and sinking important for PLC?

Understanding sourcing and sinking is important for PLC because it helps in correctly selecting the field devices and ensuring the proper flow of current in the circuit.

What does the video discuss about the connection inside a PLC?

The video discusses how connections are made inside a PLC, specifically how the input section and output devices are connected and interact with each other.

What is the significance of the common terminal in the input section?

The common terminal in the input section is significant as it determines the potential of the circuit. It is connected to the source of the input voltage.

How does the video explain the concept of sourcing?

The video explains sourcing as the process where the current flows from a high potential (source) to a low potential (load), and it is crucial for the proper functioning of the PLC circuit.

What is the role of the field devices in the context of sourcing and sinking?

Field devices play a crucial role in sourcing and sinking as they determine the type of sensors (MP and PT) based on the voltage supplied to the common terminal.

What happens when the input section receives zero volts?

When the input section receives zero volts, the circuit is completed, and the output from the field devices will be zero volts, completing the circuit.

How does the video clarify the concept of sinking?

The video clarifies sinking as the flow of current from the load towards the source, which is the opposite of sourcing.

What is the importance of understanding the flow of current in PLC?

Understanding the flow of current in PLC is important as it helps in determining the correct operation of the system, ensuring that the current flows from the source to the load as intended.

What advice does the video give for those who have doubts about the concept?

The video advises viewers to clear their doubts about the concept, emphasizing that it is an important topic in PLC and encourages them to like, share, and subscribe to the channel for more information.
