2614. As shown in the illustrated block diagram for a programmable logic controller system, what functional component is used to convey signals from the processor to motor starter coils, valve solenoids, and other such devices

Output modules (DC, AC, and analog) transmit signals from the processor to field devices, such as motor starters and valve solenoids. Input modules receive signals, the processor executes logic, the power supply provides power, and these functions are distinct from conveying signals to external devices.
