The output interface module connects to load devices such as lamps or solenoids

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

The main idea is that the output interface module is what drives external devices. It provides the electrical path and switching capability that energizes loads like lamps and solenoids when the PLC outputs a signal. In a typical PLC, output modules use relay contacts or transistor outputs to switch current to the connected loads, turning them on or off according to the control program. This means the statement is true: the output interface connects to and controls load devices. Options suggesting uncertainty, variability, or that it doesn’t connect to loads don’t fit the actual function, since driving loads is exactly what the output interface is designed to do.
