Prototype Design of an Electro-Pneumatic Trainer Board

Electro-pneumatics is successfully used in many areas of industrial automation, production, assembly and packaging systems worldwide are driven by electro pneumatic control systems. The unavailability of electro-pneumatic trainer board in CETD makes students not aware of the importance on how pneumatic system are used in the industrial field. Having Electro pneumatic trainer board in the technical laboratory will help students be familiarized on the operation of the pneumatic system that will give them knowledge in the trouble shooting of any equipment that is powered and operated by pneumatics system. From this, the researchers came up with an idea of creating a Electro-pneumatic trainer board using relays. The designed circuit of electro-pneumatic trainer board was composed of different control elements just like relays, timers, switches, and indicator lights. The ac source is converted by dc power supply to produce dc voltage to energize the components has a low voltage rating. The relay has one or two more contacts to operate and control the motion of cylinder. It used solenoid valve to control the advance and retract operation of the double acting cylinder. The evaluation results showed that the electro-pneumatic trainer board helped the students in learning how to design and analyze the circuit. The testing results showed that the prototype can operate simultaneously and functioning well. The outcome of the survey indicates the necessity of the prototype.
