report is to elaborate the achievements in Programmble Logic Controllers as well as their implementation in the current engineering world. A PLC (i.e. Programmable Logic Controller) is a device that was invented to replace the necessary sequential relay circuits for machine control. The PLC works by looking at its inputs and depending upon their state‚ turning on/off its outputs. The user enters a program‚ usually via software‚ that gives the desired results. PLCs are used in many "real world"

had left lying around the school and throwing it away‚ it helped bring a more positive environment towards the school setting. My commitment towards making a positive impact in the community began with joining Relay For Life‚ which is a fundraising opportunity towards cancer research. Relay For Life has made a positive impact in the community because the money fundraised goes towards finding a cure for cancer. I had also made a positive difference in the community‚ and even overseas‚ by packaging

Introduction: Lighting is an essential service in all the industries. The power consumption by the indusrtial lighting varies between 2% to 10% of the total power depending on the type of industry. Innovation and continuous improvement in the field of lighting‚ has given rise to tremendous energy saving opportunities in this area. The simplest and the most widely used form of controlling a lighting installation is "On-Off" switch. In the electrical lighting system in our community‚ especially

Contactors 6 Thermal overload relay THEORY INTRODUCTION TO D.O.L STARTER D.O.L starter is a widely-used starting method of electric motor. there are many type of motor starter‚ the simplest of which is the DOL starter. The D.O.L starter comprises a switch and an overload protection relay. The switch may be manually operated load break switch or circuit breaker‚ but more commonly it would be an electromagnetic contactor which can be opened by the thermal overload relay under fault conditions. Typically
