Why you use plc in water treatment?

Answer 1

micro controllerer out put handling capacity is low,i hope you know about fan out

for example micro controller cant control a induction motor directly,but plc can control ,it has the ability to hand such kva capacity,but the funny thing is inside the plc there are combination of microcontrollers,dont get confuse,these controllers has been specially designed and supported by sufficient hardware,

so you can understand main difference is additional harware support to handle larage currents and voltage spikes,

an microcontroller output will be 0v or 5v and it can handle only few micro amperes,

so can you control a motor or robotic arm or any indicating bulbs,or solonoid relays?answer is no you cant,,you need more power.so the controller out put is being amplified to without distortion ,and doing the same job which was determined by the controller but it cant do it alone without power amp.

Answer 2

The softwiring advantage provided by programmable controllers is

tremendous. In fact, it is one of the most important features of PLCs.

Softwiring makes changes in the control system easy and cheap. If

you want a device in a PLC system to behave differently or to control

a different process element, all you have to do is change the control

program. In a traditional system, making this type of change would

involve physically changing the wiring between the devices, a costly

and time-consuming endeavor.

Answer 3

PLCs (Programmable Logic Controllers) are used in water treatment systems to automate and control various processes such as monitoring water quality, controlling chemical dosing, regulating flow rates, and managing equipment operation. Their reliability, versatility, and ability to integrate with different sensors and devices make them essential for optimizing the efficiency and effectiveness of water treatment operations.
