EXECUTIVE SUMMARY: This study aimed to develop and construct Programmable Logic Control Vault Lock System. Specifically, it aimed to design and construct the Programmable Logic Control Vault Lock System, made of locally available materials, evaluate the acceptability of the project in terms of functionality, safety, maintenance, durability, and usefulness for test the significant difference of the evaluation made by the experts and end-users. The researchers made questionnaire checklist was used to determine the level of acceptability of the Programmable Logic Control Vault Lock System. This was validated by the Electrical/Electronic Technology Instructors from the College of Industrial Technology. The respondents provided pertinent information crucial to the completion of this study. The results were tallied and computed for the acceptability of the project. The first group was ten (10) experts who have knowledge, skills and understanding on electrical and electronics operations, the other fifteen (15) were the End-users who would possibly use the Programmable Logic Control Vault Lock System. The statistical treatment utilized were the mean and the independent t-test. The t-test was used to test if there is any significant difference on the perception of the end user. On the acceptability of the Programmable Logic Control Vault Lock System in terms of functionality, safety, maintenance, durability and usefulness, it obtained excellent as evaluated by the experts and end-users. The Programmable Logic Control Vault Lock System was designed and constructed out of locally available materials. The project was very much accepted as evaluated by the respondents. The computed t-value in terms of functionality, safety, maintenance, durability and usefulness showed that there is no significant difference on the evaluation made by the experts and end-users. It was recommended that numerical keypad for control must be provided and further research must be conducted to enhance the device's features and capabilities. Finally, the developed device should be submitted to the university evaluating committee to determine whether the device is possible to be mass produced as training material for teaching the subject.
