Which category includes Power Conductors, Power Transistors, and Power Thyristors?

• A. Electric/Electronics for Processing Elements (Control Elements)
• B. Pneumatics/Hydraulics for Processing Elements (Control Elements)
• C. Pneumatics/Hydraulics for Working Elements
• D. Electric/Electronics for Input Elements

Answer: (A)

Power Conductors, Power Transistors, and Power Thyristors are electrical/electronic devices that control and switch electrical power in a circuit. They are used to regulate the power delivered to a load, which is the role of a control element in a system. That’s why they fit in Electric/Electronics for Processing Elements (Control Elements): these components form the electronic means by which the process variable is managed, rather than being fluid-power actuators or sensing devices. Pneumatics/Hydraulics would cover fluid power and motion devices, not electrical power control. Input elements are sensors that convert physical quantities into electrical signals, not devices that control power to a load. So the best fit is Electric/Electronics for Processing Elements (Control Elements).
