Turning outputs on or off through relay contacts is called...

• A. Relay Control
• B. Control Logic
• C. Power Switching
• D. Logic Sequencing

Answer: (B)

Turning outputs on or off through relay contacts is control logic. The relay coil is energized or de-energized based on input conditions, and the matching contacts act as switches that deliver or cut power to the outputs. This setup implements the logical decisions that determine output states, built from how the inputs combine to drive the relays. It’s more precise than simply “power switching,” which describes the hardware act of switching power, and it’s not about sequencing order or steps, which implies a timed progression rather than direct input-driven control.
