Design an electro-pneumatic circuit that will control a single-acting cylinder. when the circuit is actuated the piston will repeatedly extend and retract. a) show pneumatic and electrical circuits for direct control of the system described above, i. e. no relays are used in the electrical circuit. b) show pneumatic and electrical circuits for indirect control, i. e., each switch indirectly controls the output components via a relay. redesign your circuit incorporating a quick exhaust valve so that the piston can retract more easily and a flow control valve to control piston forward speed.
