Which of the following is NOT a typical input count for PLC discrete input modules?

Explanation:
Discrete input modules are used to read binary signals from field devices, and they’re typically offered in standard, manageable sizes. You’ll generally encounter small to mid-size cards that read a modest number of inputs, balancing wiring complexity, backplane addressing, and scan performance. A single module that handles a very large number of inputs is less common because it can be more expensive, harder to wire and diagnose, and often leads to splitting the workload across multiple modules for reliability and easier maintenance. So the option describing a very large single-module input count is the not-typical choice.
