c) power rating of the I\/O modules. <\/p>\n\n\n\n
d) cost of the I\/O modules.<\/p>\n\n\n\n
The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n The correct answer is: Programmable Logic Controllers (PLCs) are industrial digital computers designed for automation and control applications. They are categorized based on several parameters, but the number of Input\/Output (I\/O) points<\/strong> is the primary classification criterion.<\/p>\n\n\n\n I\/O points refer to the number of input and output devices a PLC can handle. Inputs include sensors, switches, and buttons, while outputs include relays, motors, and actuators. The number of I\/O points determines the complexity of the system a PLC can control.<\/p>\n\n\n\n Thus, PLCs are mainly categorized by their number of I\/O points<\/strong>, which directly impacts their capability and application range.<\/p>\n","protected":false},"excerpt":{"rendered":" Programmable logic controllers are categorized according to the a) number of I\/O points. b) current rating of I\/O modules. c) power rating of the I\/O modules. d) cost of the I\/O modules.
