Electropneumatic systems combine pneumatic actuators and controllers with electric control circuits. Pneumatic actuators include cylinders, motors, and valves, which are powered by compressed air. However, the electric control circuits use electrical components like switches, relays, and programmable logic controllers to control the flow of compressed air and automate pneumatic processes. While pneumatic systems can be complicated to control, electropneumatic systems simplify control with digital electric signals regulating complex pneumatic circuits and multiple actuators.

- 34. Solenoid principles (Coil & core) When an electric current flows through a coil, a magnetic field is generated. The following applies to strengthen the magnetic field: 1. Increasing the number of windings (1loop, 2 loop, 3 loop, etc) 2. Increasing the strength of the current (1 A, 2A, etc) The following applies to the weaken the magnetic field: 1. Lengthening the coil reduces the field. (the soft iron core length)
