Question

All of the following are example of discrete control systems except ?
A) a light switch.
B) the ignition button on a boat.
C) the volume control on a sound system.
D) the power button on the remote control.

Answer 1

'The ignition button on a boat' is not an example of discrete control systems.

Option: B

Explanation:

• Discrete control can be utilized for processes that involve discrete inputs and outputs along with their instrumentation device.  
• These discrete control systems can be classified as open loop control and sequential control with interlocks.
• This discrete control can be considered as one of the major subsystems in the automation field and the manufacturing sectors used for growth and maturity.
• The discrete control have started the journey with sensors and relays wired. Some of the examples are light switch, power buttons, and so on.

Answer 2

Answer: The Volume Control on a sound system.

Explanation:

To put it simply, discrete control systems are more often than not just a simple 'switch' or a 'button'. A volume control is the most visually complex out of these 4 options, something that requires turning and twisting, and maybe pressing, is less discrete than the other options.
