The relay logic diagram consists of four rungs. Each rung contains various components such as normally open push buttons, relay coils (CR1 and CR2), normally open and normally closed contacts, solenoid coils (Sol 1 and Sol 2), and a 5/3 directional control valve connected to a cylinder. This setup facilitates the control of the cylinder’s movement using two buttons, a valve, and corresponding electrical components. #mechatronics #plcprogramming #programming #programmer #controlsengineering #auto
