A. By using a single input/output (I/O) module
B. By using multiple input/output (I/O) modules
C. By using a single input module and multiple output modules
D. By using multiple input modules and a single output module
Answer:B

A. By using a single input/output (I/O) module B. By using multiple input/output (I/O) modules C. By using a single input module and multiple output modules D. By using multiple input modules and a single output module
Explanation: PLCs can handle multiple inputs and outputs by using multiple input/output (I/O) modules. These modules connect to sensors and actuators in the industrial process and are connected to the PLC’s central processing unit (CPU) to read and send signals. This allows the PLC to control and monitor multiple points in the industrial process.
