The origin of automation can be traced back to the eighteenth century, people began to replace a large number of human and animal power with mechanical power. With the development of science and technology, electronic, computer, optical detection and other fields, the concept of machine and manipulation has become complex, automation has gradually become a comprehensive automatic detection, feedback, judgment, control and other direct control of the automatic operation system in the form of program instructions. Now, through electronic power technology, industrial automation has jumped to a new stage, a complete industrial automation system has been able to carry out intelligent control, automatic completion of program setting, control and movement. With knowledge of electronic power and automatic control and many years of experience, Delta has continued to expand its product line and develop programmable logic controllers in the field of industrial automation over the past decade. And into the field of motion control. Today, Delta industrial automation products,
