Why 24 Volts DC Power Supply is used in Industrial Automation Systems ? 🤔

________

- DC supply is used in all major industrial automation and control systems.

- We have seen that a majority of sensors, instruments, and other control devices use a 24V DC power supply. 

- Times have also advanced nowadays in such a way that some motors use 24V DC for energizing.

Why 24 Volts DC Power Supply? 

What is it that DC supply is preferred over AC supply is powering the instruments?  

- We will have a look at some of the general advantages of DC supply and try to correlate it with AC supply.

_________

ADVANTAGES OF USING 24V DC SUPPLY 

- One main advantage of a 24V DC supply is less arc generation. AC supply of 120V or 230V is highly risky considering that it p…

________

- Although DC supply has many advantages, it has some demerits too.

Let us have a look at some of them ; 

- One main disadvantage of DC supply is that it cannot be used for longer distances. There is reduction in signal capacity at long distances.

- 24V DC supply cannot be used to drive high current loads.

- These are the general demerits of a 24 Volts DC power supply; but overall, it is best suitable for most of the instruments and devices as compared to 230V AC supply.
