Abstract: In the modern era for greater efficiency automation is essential for increased productivity, improved quality, reduction process inventory and increased safety of working personal etc. A product that is highly reliable quality yet cost effective only services in the competitive today. Automation takes part in every manufacturing, controlling process and testing of equipment. Now a day’s contactors are useful in commercial and industrial applications, particularly for controlling large lighting loads and motors. Hence testing of contactor is prime important. The main aim of our project is to test contactor parameters using programmable logic controller. We are performing flashing and coil continuity test, coil holding test, pole continuity test, pick up time test and drop off time test. It tests the product automatically & displays result as either PASS or FAIL. In our project the whole system is carried out automatically and manually with the help of plc. Further due to benefits of automation data recording facilities can be also provided with test bench so that it will be easy to check for rejected product fault. In conclusion Plc. Contactor testing has advantages over manual testing of contactor.
