Question

Discrete control valves are either open or closed. Since these valves have only two states, they do not require analog input signals and operate simply by applying the appropriate voltage to the coil of the valve. True or False

Answer 1

Discrete control valves are either open or closed, making them on-off switches that do not require analog input signals.

Step-by-step explanation:

True. Discrete control valves are either open or closed, which means they have only two states. They do not require analog input signals and operate simply by applying the appropriate voltage to the coil of the valve. This is because they function as on-off switches, similar to how a transistor behaves in a digital circuit.
