Which term describes how many inputs a PLC module can monitor?

• A. Number of Inputs
• B. Type of Current
• C. Level of Voltage
• D. Output Module Load Capability

Answer: (A)

The main idea here is the capacity of the input side—specifically, how many input points a PLC module can monitor at once. The term that exactly describes this is the number of inputs (often seen as input count or I/O count in specs). It tells you how many sensors or switches you can connect and read with that module. The other factors describe different qualities: the type of current indicates whether inputs are DC or AC, the level of voltage refers to the voltage range the inputs accept, and the output module load capability deals with how much load the module’s outputs can drive. None of those describe how many inputs the module can monitor, which is why the correct term is the number of inputs.
