What is the maximum number of inputs and outputs that are there in a small PLC?

What is the maximum number of inputs and outputs that are there in a small PLC? Correct Answer 200

Designing an efficient Programmable Logic Controller:

PLCs are classified into following the main categories based on the number of input and outputs they can handle:

Nano PLC: PLC that has less than 32 input/output (I/O) functions.

Micro PLC: PLC that has more than 32 Input/Output (I/O) points but not more than 128 input/output (I/O) functions.

Small PLC:

  • PLC that has more than 128 Input and Output (I/O) points but not more than 256 I/O functions.
  • It does not include any I/O enhancements fitted along with the basic system.
  • Hence according to options, the maximum number of inputs and outputs that are there in a small PLC is 200.
     

Medium and Large PLC: PLC that controls a large number (>256) of discrete elements using very fast input/output (I/O) scan times.

Which of the following statements is/are correct? 1. A system is said to be Finite Impulse Response (FIR), if the output samples of the system depend only on the present input and a finite number of past or previous input samples. 2. If the output of a system y(n) depends only on the present input and past inputs, but not on past outputs, then it is called a non-recursive system. 3. If the output of a system y(n) depends only on the present input and past inputs, but not on past outputs, then it is called a recursive system.
