An output instruction in a PLC can energize which of the following?

An output instruction in a PLC can energize which of the following?

• A. Timers, counters, conversions, latch, unlatch
• B. Only physical outputs
• C. Arithmetic operations only
• D. Data file I/O operations

Answer: (C)

An output instruction in a PLC is the action that drives a device by energizing its connected path. It directly controls physical outputs like coils or relays, turning them on or off. Arithmetic operations are handled by separate arithmetic instructions, not by output instructions. Timers, counters, conversions, and latch/unlatch are internal functions that manage timing, counting, data type changes, or memory state, rather than energizing hardware. Data file I/O operations deal with reading or writing data, not driving outputs. So the effect of an output instruction is to energize physical outputs.
