A PLC module can have how many terminals?

• A. 4
• B. 8, 16, 32
• C. 24
• D. 40

Answer: (B)

The number of terminals on a PLC I/O module corresponds to how many separate field connections you can wire to that module. In practical PLC designs, these modules are made in standard sizes to match typical I/O needs and keep wiring manageable. The common configurations are eight, sixteen, or thirty-two terminals per module, representing 8-point, 16-point, or 32-point I/O capability. This standardization makes it easy to scale by adding more modules as the system grows. Counts like four, twenty-four, or forty terminals aren’t typical single-module configurations, though you might encounter nonstandard or specialty modules in some cases. So, a PLC module commonly has eight, sixteen, or thirty-two terminals.
