What does the 'Number of Outputs' feature specify for a PLC discrete output module?

• A. The number of devices the module can control
• B. The voltage level of the module
• C. The current rating per output
• D. The color of connectors

Answer: (A)

The Number of Outputs shows how many devices the module can switch on or off independently. Each output channel controls a separate load, like a relay or transistor, so the total count defines how many loads the module can drive at once. The voltage level per output, the current rating per output, and cosmetic details like connector color are separate specifications and do not define how many devices you can control. So a module with more outputs can handle more devices, while the other factors describe how those outputs operate and are within safe limits.
