The Origins of PLC Technology PLC were originally developed to replace traditional relay-based control panels. Relay racks were widely used in early industrial automation, but they presented several significant challenges. They required large installation spaces, consumed considerable amounts of electrical power, and involved high installation and maintenance costs. Whenever manufacturers needed t...
What Are Motors and Encoders in Industrial Automation? An industrial motor converts electrical energy into mechanical motion. Depending on the application, motors may drive conveyors, pumps, robotic arms, machine tools, packaging equipment, fans, or other automated machinery. An encoder is a feedback device that monitors the motor shaft or machine movement and sends information to a controller or ...
