Electro-pneumatic control systems are built with electrical components to control pneumatic components (for example through electrically operated valves).
The working medium, compressed air, is controlled by electrical signals.
[1] In contrast to purely pneumatic controls, electro-pneumatic controls allow significantly more complex functions, especially through the use of electronic circuits such as programmable logic controls.
[2] The advantage of pneumatics lies in the simple and cost-effective implementation of actuators, for example with pneumatic cylinders.
