Here are the solutions to the questions from the image: 1. Analyze the ladder logic diagram in Fig. 3. The ladder logic diagram in Fig. 3 shows a control circuit for output Y. There are two parallel branches connected to the output coil Y. The first branch consists of normally open (NO) contacts A and C connected in series. The second branch consists of normally open (NO) contacts B and D connected in series. For output Y to be energized (ON), either the first branch must be complete OR the second branch must be complete. This means Y will be ON if (A is closed AND C is closed) OR (B is closed AND D is closed). The Boolean expression for the output Y is: Y = (A AND C) OR (B AND D). --- 2. With the aid of a schematic diagram, describe the operation of a single solenoid 5/2 pneumatic directional control valve. A single solenoid 5/2 pneumatic directional control valve has five ports and two switching positions. It is actuated by an electrical signal to a solenoid and typically returns to its default position by a spring.
