What is the primary purpose of electro-pneumatic systems?

• To store electrical energy

• To control the motion of mechanical systems using compressed air and electrical signals

• To generate hydraulic power

• To convert chemical energy into mechanical energy

What is the function of a single-acting cylinder in an electro-pneumatic system?

• It moves in both forward and backward directions

• It moves only in one direction and returns by a spring force

• It stores compressed air

• It controls the speed of airflow

Which component is responsible for switching the flow of compressed air in an electro-pneumatic circuit?

• Motor

• Relay

• Valve

• Pressure gauge

A double-acting cylinder requires compressed air:

• On both sides of the piston for bidirectional motion

• Only on one side for a single movement

• To store energy for future use

• To operate as a sensor

Which type of valve is commonly used to control a single-acting cylinder?

• 3/2-way valve

• 5/2-way valve

• 5/3-way valve

• Check valve

In an electro-pneumatic system, solenoid valves are activated by:

• Hydraulic pressure

• Electrical signals

• Mechanical levers

• Compressed air

What is the main advantage of using electro-pneumatic control systems in industrial applications?

• They operate without requiring electricity

• They provide precise and automated control of pneumatic actuators

• They consume less air than traditional pneumatic systems

• They are independent of any external control signals

Which of the following components is NOT typically found in an electro-pneumatic circuit?

• Solenoid valve

• Air compressor

• Hydraulic pump

• Pushbutton switch

A 5/2-way valve is primarily used for:

• Controlling a single-acting cylinder

• Controlling a double-acting cylinder

• Increasing air pressure

• Measuring airflow

The COM3LAB - LD Didactic training kit is used in this experiment to:

• Control a hydraulic system

• Train students on the basic principles of electro-pneumatics

• Measure electrical resistance

• Convert pneumatic power to hydraulic power
